Merge tag 'char-misc-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver update from Greg Kroah-Hartman:
 "Here's the big char / misc driver update for 3.10-rc1

  A number of various driver updates, the majority being new
  functionality in the MEI driver subsystem (it's now a subsystem, it
  started out just a single driver), extcon updates, memory updates,
  hyper-v updates, and a bunch of other small stuff that doesn't fit in
  any other tree.

  All of these have been in linux-next for a while"

* Qualcomm SSBI
Some Qualcomm MSM devices contain a point-to-point serial bus used to
communicate with a limited range of devices (mostly power management
chips).
These require the following properties:
- compatible: "qcom,ssbi"
- qcom,controller-type
indicates the SSBI bus variant the controller should use to talk
with the slave device. This should be one of "ssbi", "ssbi2", or
"pmic-arbiter". The type chosen is determined by the attached
slave.
The slave device should be the single child node of the ssbi device
with a compatible field.

Intel(R) Management Engine (ME) Client bus API
===============================================
Rationale
=========
MEI misc character device is useful for dedicated applications to send and receive
data to the many FW appliance found in Intel's ME from the user space.
However for some of the ME functionalities it make sense to leverage existing software
stack and expose them through existing kernel subsystems.
In order to plug seamlessly into the kernel device driver model we add kernel virtual
bus abstraction on top of the MEI driver. This allows implementing linux kernel drivers
for the various MEI features as a stand alone entities found in their respective subsystem.
Existing device drivers can even potentially be re-used by adding an MEI CL bus layer to
the existing code.
MEI CL bus API
===========
A driver implementation for an MEI Client is very similar to existing bus
based device drivers. The driver registers itself as an MEI CL bus driver through
the mei_cl_driver structure:
struct mei_cl_driver {
struct device_driver driver;
const char *name;
const struct mei_cl_device_id *id_table;
int (*probe)(struct mei_cl_device *dev, const struct mei_cl_id *id);
int (*remove)(struct mei_cl_device *dev);
};
struct mei_cl_id {
char name[MEI_NAME_SIZE];
kernel_ulong_t driver_info;
};
The mei_cl_id structure allows the driver to bind itself against a device name.
To actually register a driver on the ME Client bus one must call the mei_cl_add_driver()
API. This is typically called at module init time.
Once registered on the ME Client bus, a driver will typically try to do some I/O on
this bus and this should be done through the mei_cl_send() and mei_cl_recv()
routines. The latter is synchronous (blocks and sleeps until data shows up).
In order for drivers to be notified of pending events waiting for them (e.g.
an Rx event) they can register an event handler through the
mei_cl_register_event_cb() routine. Currently only the MEI_EVENT_RX event
will trigger an event handler call and the driver implementation is supposed
to call mei_recv() from the event handler in order to fetch the pending
received buffers.
Example
=======
As a theoretical example let's pretend the ME comes with a "contact" NFC IP.
The driver init and exit routines for this device would look like:
#define CONTACT_DRIVER_NAME "contact"
static struct mei_cl_device_id contact_mei_cl_tbl[] = {
{ CONTACT_DRIVER_NAME, },
/* required last entry */
{ }
};
MODULE_DEVICE_TABLE(mei_cl, contact_mei_cl_tbl);
static struct mei_cl_driver contact_driver = {
.id_table = contact_mei_tbl,
.name = CONTACT_DRIVER_NAME,
.probe = contact_probe,
.remove = contact_remove,
};
static int contact_init(void)
{
int r;
r = mei_cl_driver_register(&contact_driver);
if (r) {
pr_err(CONTACT_DRIVER_NAME ": driver registration failed\n");
return r;
}
return 0;
}
static void __exit contact_exit(void)
{
mei_cl_driver_unregister(&contact_driver);
}
module_init(contact_init);
module_exit(contact_exit);
And the driver's simplified probe routine would look like that:
int contact_probe(struct mei_cl_device *dev, struct mei_cl_device_id *id)
{
struct contact_driver *contact;
[...]
mei_cl_enable_device(dev);
mei_cl_register_event_cb(dev, contact_event_cb, contact);
return 0;
}
In the probe routine the driver first enable the MEI device and then registers
an ME bus event handler which is as close as it can get to registering a
threaded IRQ handler.
The handler implementation will typically call some I/O routine depending on
the pending events:
#define MAX_NFC_PAYLOAD 128
static void contact_event_cb(struct mei_cl_device *dev, u32 events,
void *context)
{
struct contact_driver *contact = context;
if (events & BIT(MEI_EVENT_RX)) {
u8 payload[MAX_NFC_PAYLOAD];
int payload_size;
payload_size = mei_recv(dev, payload, MAX_NFC_PAYLOAD);
if (payload_size <= 0)
return;
/* Hook to the NFC subsystem */
nfc_hci_recv_frame(contact->hdev, payload, payload_size);
}
}

/*
* Workaround for errata i743 - LPDDR2 Power-Down State is Not
* Efficient
*
* i743 DESCRIPTION:
* The EMIF supports power-down state for low power. The EMIF
* automatically puts the SDRAM into power-down after the memory is
* not accessed for a defined number of cycles and the
* EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field is set to 0x4.
* As the EMIF supports automatic output impedance calibration, a ZQ
* calibration long command is issued every time it exits active
* power-down and precharge power-down modes. The EMIF waits and
* blocks any other command during this calibration.
* The EMIF does not allow selective disabling of ZQ calibration upon
* exit of power-down mode. Due to very short periods of power-down
* cycles, ZQ calibration overhead creates bandwidth issues and
* increases overall system power consumption. On the other hand,
* issuing ZQ calibration long commands when exiting self-refresh is
* still required.
*
* WORKAROUND
* Because there is no power consumption benefit of the power-down due
* to the calibration and there is a performance risk, the guideline
* is to not allow power-down state and, therefore, to not have set
* the EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE bit field to 0x4.
