Commit 8b45bc89 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are changes for drivers that are intimately tied to some SoC and
  for some reason could not get merged through the respective subsystem
  maintainer tree.

  Most of the new code is for the Keystone Navigator driver, which is
  new base support that is going to be needed for their hardware
  accelerated network driver and other units.

  Most of the commits are for moving old code around from at91 and omap
  for things that are done in device drivers nowadays.

   - at91: move reset, poweroff, memory and clocksource code into
     drivers directories
   - socfpga: add edac driver (through arm-soc, as requested by Boris)
   - omap: move omap-intc code to drivers/irqchip
   - sunxi: added an RTC driver for sun6i
   - omap: mailbox driver related changes
   - keystone: support for the "Navigator" component
   - versatile: new reboot, led and soc drivers"

Device Tree Bindings for Register Bit LEDs
Register bit leds are used with syscon multifunctional devices
where single bits in a certain register can turn on/off a
single LED. The register bit LEDs appear as children to the
syscon device, with the proper compatible string. For the
syscon bindings see:
Documentation/devicetree/bindings/mfd/syscon.txt
Each LED is represented as a sub-node of the syscon device. Each
node's name represents the name of the corresponding LED.
LED sub-node properties:
Required properties:
- compatible : must be "register-bit-led"
- offset : register offset to the register controlling this LED
- mask : bit mask for the bit controlling this LED in the register
typically 0x01, 0x02, 0x04 ...
Optional properties:
- label : (optional)
see Documentation/devicetree/bindings/leds/common.txt
- linux,default-trigger : (optional)
see Documentation/devicetree/bindings/leds/common.txt
- default-state: (optional) The initial state of the LED. Valid
values are "on", "off", and "keep". If the LED is already on or off
and the default-state property is set the to same value, then no
glitch should be produced where the LED momentarily turns off (or
on). The "keep" setting will keep the LED at whatever its current
state is, without producing a glitch. The default is off if this
property is not present.
Example:
syscon: syscon@10000000 {
compatible = "arm,realview-pb1176-syscon", "syscon";
reg = <0x10000000 0x1000>;

OMAP2+ Mailbox Driver
=====================
The OMAP mailbox hardware facilitates communication between different processors
using a queued mailbox interrupt mechanism. The IP block is external to the
various processor subsystems and is connected on an interconnect bus. The
communication is achieved through a set of registers for message storage and
interrupt configuration registers.
Each mailbox IP block has a certain number of h/w fifo queues and output
interrupt lines. An output interrupt line is routed to an interrupt controller
within a processor subsystem, and there can be more than one line going to a
specific processor's interrupt controller. The interrupt line connections are
fixed for an instance and are dictated by the IP integration into the SoC
(excluding the SoCs that have a Interrupt Crossbar IP). Each interrupt line is
programmable through a set of interrupt configuration registers, and have a rx
and tx interrupt source per h/w fifo. Communication between different processors
is achieved through the appropriate programming of the rx and tx interrupt
sources on the appropriate interrupt lines.
The number of h/w fifo queues and interrupt lines dictate the usable registers.
All the current OMAP SoCs except for the newest DRA7xx SoC has a single IP
instance. DRA7xx has multiple instances with different number of h/w fifo queues
and interrupt lines between different instances. The interrupt lines can also be
routed to different processor sub-systems on DRA7xx as they are routed through
the Crossbar, a kind of interrupt router/multiplexer.
Mailbox Device Node:
====================
A Mailbox device node is used to represent a Mailbox IP instance within a SoC.
The sub-mailboxes are represented as child nodes of this parent node.
Required properties:
--------------------
- compatible: Should be one of the following,
"ti,omap2-mailbox" for OMAP2420, OMAP2430 SoCs
"ti,omap3-mailbox" for OMAP3430, OMAP3630 SoCs
"ti,omap4-mailbox" for OMAP44xx, OMAP54xx, AM33xx,
AM43xx and DRA7xx SoCs
- reg: Contains the mailbox register address range (base
address and length)
- interrupts: Contains the interrupt information for the mailbox
device. The format is dependent on which interrupt
controller the OMAP device uses
- ti,hwmods: Name of the hwmod associated with the mailbox
- ti,mbox-num-users: Number of targets (processor devices) that the mailbox
device can interrupt
- ti,mbox-num-fifos: Number of h/w fifo queues within the mailbox IP block
Child Nodes:
============
A child node is used for representing the actual sub-mailbox device that is
used for the communication between the host processor and a remote processor.
Each child node should have a unique node name across all the different
mailbox device nodes.
Required properties:
--------------------
- ti,mbox-tx: sub-mailbox descriptor property defining a Tx fifo
- ti,mbox-rx: sub-mailbox descriptor property defining a Rx fifo
Sub-mailbox Descriptor Data
---------------------------
Each of the above ti,mbox-tx and ti,mbox-rx properties should have 3 cells of
data that represent the following:
Cell #1 (fifo_id) - mailbox fifo id used either for transmitting
(ti,mbox-tx) or for receiving (ti,mbox-rx)
Cell #2 (irq_id) - irq identifier index number to use from the parent's
interrupts data. Should be 0 for most of the cases, a
positive index value is seen only on mailboxes that have
multiple interrupt lines connected to the MPU processor.
Cell #3 (usr_id) - mailbox user id for identifying the interrupt line
associated with generating a tx/rx fifo interrupt.
Example:
--------
/* OMAP4 */
mailbox: mailbox@4a0f4000 {
compatible = "ti,omap4-mailbox";
reg = <0x4a0f4000 0x200>;
interrupts = <GIC_SPI 26 IRQ_TYPE_LEVEL_HIGH>;

* sun6i Real Time Clock
RTC controller for the Allwinner A31
Required properties:

- reg : physical base address of the controller and length of
memory mapped region.
- interrupts : IRQ lines for the RTC alarm 0 and alarm 1, in that order.

Keystone Navigator DMA Controller
This document explains the device tree bindings for the packet dma
on keystone devices. The Keystone Navigator DMA driver sets up the dma
channels and flows for the QMSS(Queue Manager SubSystem) who triggers
the actual data movements across clients using destination queues. Every
client modules like NETCP(Network Coprocessor), SRIO(Serial Rapid IO),
CRYPTO Engines etc has its own instance of dma hardware. QMSS has also
an internal packet DMA module which is used as an infrastructure DMA
with zero copy.
Navigator DMA cloud layout:
------------------
| Navigator DMAs |
------------------
|
|-> DMA instance #0
|
|-> DMA instance #1
.
.
|
|-> DMA instance #n
Navigator DMA properties:
Required properties:
- compatible: Should be "ti,keystone-navigator-dma"
- clocks: phandle to dma instances clocks. The clock handles can be as
many as the dma instances. The order should be maintained as per
the dma instances.
- ti,navigator-cloud-address: Should contain base address for the multi-core
navigator cloud and number of addresses depends on SOC integration
configuration.. Navigator cloud global address needs to be programmed
into DMA and the DMA uses it as the physical addresses to reach queue
managers. Note that these addresses though points to queue managers,
they are relevant only from DMA perspective. The QMSS may not choose to
use them since it has a different address space view to reach all
its components.
DMA instance properties:
Required properties:
- reg: Should contain register location and length of the following dma
register regions. Register regions should be specified in the following
order.
- Global control register region (global).

- Rx DMA flow configuration register region (rxflow).
Optional properties:
- reg-names: Names for the register regions.
- ti,enable-all: Enable all DMA channels vs clients opening specific channels
what they need. This property is useful for the userspace fast path
case where the linux drivers enables the channels used by userland
stack.
- ti,loop-back: To loopback Tx streaming I/F to Rx streaming I/F. Used for
infrastructure transfers.
- ti,rx-retry-timeout: Number of dma cycles to wait before retry on buffer
starvation.

* Texas Instruments Keystone Navigator Queue Management SubSystem driver
The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
the main hardware sub system which forms the backbone of the Keystone
multi-core Navigator. QMSS consist of queue managers, packed-data structure
processors(PDSP), linking RAM, descriptor pools and infrastructure
Packet DMA.
The Queue Manager is a hardware module that is responsible for accelerating
management of the packet queues. Packets are queued/de-queued by writing or
reading descriptor address to a particular memory mapped location. The PDSPs
perform QMSS related functions like accumulation, QoS, or event management.
Linking RAM registers are used to link the descriptors which are stored in
descriptor RAM. Descriptor RAM is configurable as internal or external memory.
The QMSS driver manages the PDSP setups, linking RAM regions,
queue pool management (allocation, push, pop and notify) and descriptor
pool management.
Required properties:
- compatible : Must be "ti,keystone-navigator-qmss";
- clocks : phandle to the reference clock for this device.
- queue-range : <start number> total range of queue numbers for the device.
- linkram0 : <address size> for internal link ram, where size is the total
link ram entries.
- linkram1 : <address size> for external link ram, where size is the total
external link ram entries. If the address is specified as "0"
driver will allocate memory.
- qmgrs : child node describing the individual queue managers on the
SoC. On keystone 1 devices there should be only one node.
On keystone 2 devices there can be more than 1 node.
-- managed-queues : the actual queues managed by each queue manager
instance, specified as <"base queue #" "# of queues">.
-- reg : Address and size of the register set for the device.
Register regions should be specified in the following
order
- Queue Peek region.
- Queue status RAM.
- Queue configuration region.
- Descriptor memory setup region.
- Queue Management/Queue Proxy region for queue Push.
- Queue Management/Queue Proxy region for queue Pop.
- queue-pools : child node classifying the queue ranges into pools.
Queue ranges are grouped into 3 type of pools:
- qpend : pool of qpend(interruptible) queues
- general-purpose : pool of general queues, primarly used
as free descriptor queues or the
transmit DMA queues.
- accumulator : pool of queues on PDSP accumulator channel
Each range can have the following properties:
-- qrange : number of queues to use per queue range, specified as
<"base queue #" "# of queues">.
-- interrupts : Optional property to specify the interrupt mapping
for interruptible queues. The driver additionaly sets
the interrupt affinity hint based on the cpu mask.
-- qalloc-by-id : Optional property to specify that the queues in this
range can only be allocated by queue id.
-- accumulator : Accumulator channel specification. Any of the PDSPs in
QMSS can be loaded with the accumulator firmware. The
accumulator firmware’s job is to poll a select number of
queues looking for descriptors that have been pushed
into them. Descriptors are popped from the queue and
placed in a buffer provided by the host. When the list
becomes full or a programmed time period expires, the
accumulator triggers an interrupt to the host to read
the buffer for descriptor information. This firmware
comes in 16, 32, and 48 channel builds. Each of these
channels can be configured to monitor 32 contiguous
queues. Accumulator channel property is specified as:
<pdsp-id, channel, entries, pacing mode, latency>
pdsp-id : QMSS PDSP running accumulator firmware
on which the channel has to be
configured
channel : Accumulator channel number
entries : Size of the accumulator descriptor list
pacing mode : Interrupt pacing mode
0 : None, i.e interrupt on list full only
1 : Time delay since last interrupt
2 : Time delay since first new packet
3 : Time delay since last new packet
latency : time to delay the interrupt, specified
in microseconds.
-- multi-queue : Optional property to specify that the channel has to
monitor upto 32 queues starting at the base queue #.
- descriptor-regions : child node describing the memory regions for keystone
navigator packet DMA descriptors. The memory for
descriptors will be allocated by the driver.
-- id : region number in QMSS.
-- region-spec : specifies the number of descriptors in the
region, specified as
<"# of descriptors" "descriptor size">.
-- link-index : start index, i.e. index of the first
descriptor in the region.
Optional properties:
- dma-coherent : Present if DMA operations are coherent.
- pdsps : child node describing the PDSP configuration.
-- firmware : firmware to be loaded on the PDSP.
-- id : the qmss pdsp that will run the firmware.
-- reg : Address and size of the register set for the PDSP.
Register regions should be specified in the following
order
- PDSP internal RAM region.
- PDSP control/status region registers.
- QMSS interrupt distributor registers.
- PDSP command interface region.
