Merge tag 'nand/for-4.12' of github.com:linux-nand/linux into MTD 

From Boris:
"""
This pull request contains:

 - some minor fixes/improvements on existing drivers (fsmc, gpio, ifc,
   davinci, brcmnand, omap)
 - a huge cleanup/rework of the denali driver accompanied with core
   fixes/improvements to simplify the driver code
 - a complete rewrite of the atmel driver to support new DT bindings
   make future evolution easier
 - the addition of per-vendor detection/initialization steps to avoid
   extending the nand_ids table with more extended-id entries

Atmel NAND flash
Atmel NAND flash controller bindings
The NAND flash controller node should be defined under the EBI bus (see
Documentation/devicetree/bindings/memory-controllers/atmel,ebi.txt).
One or several NAND devices can be defined under this NAND controller.
The NAND controller might be connected to an ECC engine.
* NAND controller bindings:
Required properties:
- compatible: should be one of the following
"atmel,at91rm9200-nand-controller"
"atmel,at91sam9260-nand-controller"
"atmel,at91sam9261-nand-controller"
"atmel,at91sam9g45-nand-controller"
"atmel,sama5d3-nand-controller"
- ranges: empty ranges property to forward EBI ranges definitions.
- #address-cells: should be set to 2.
- #size-cells: should be set to 1.
- atmel,nfc-io: phandle to the NFC IO block. Only required for sama5d3
controllers.
- atmel,nfc-sram: phandle to the NFC SRAM block. Only required for sama5d3
controllers.
Optional properties:
- ecc-engine: phandle to the PMECC block. Only meaningful if the SoC embeds
a PMECC engine.
* NAND device/chip bindings:
Required properties:
- reg: describes the CS lines assigned to the NAND device. If the NAND device
exposes multiple CS lines (multi-dies chips), your reg property will
contain X tuples of 3 entries.
1st entry: the CS line this NAND chip is connected to
2nd entry: the base offset of the memory region assigned to this
device (always 0)
3rd entry: the memory region size (always 0x800000)
Optional properties:
- rb-gpios: the GPIO(s) used to check the Ready/Busy status of the NAND.
- cs-gpios: the GPIO(s) used to control the CS line.
- det-gpios: the GPIO used to detect if a Smartmedia Card is present.
- atmel,rb: an integer identifying the native Ready/Busy pin. Only meaningful
on sama5 SoCs.
All generic properties described in
Documentation/devicetree/bindings/mtd/{common,nand}.txt also apply to the NAND
device node, and NAND partitions should be defined under the NAND node as
described in Documentation/devicetree/bindings/mtd/partition.txt.
* ECC engine (PMECC) bindings:
Required properties:
- compatible: should be one of the following
"atmel,at91sam9g45-pmecc"
"atmel,sama5d4-pmecc"
"atmel,sama5d2-pmecc"
- reg: should contain 2 register ranges. The first one is pointing to the PMECC
block, and the second one to the PMECC_ERRLOC block.
Example:
pmecc: ecc-engine@ffffc070 {
compatible = "atmel,at91sam9g45-pmecc";
reg = <0xffffc070 0x490>,
<0xffffc500 0x100>;
};

compatible = "atmel,sama5d3-ebi";
#address-cells = <2>;
#size-cells = <1>;
atmel,smc = <&hsmc>;
reg = <0x10000000 0x10000000
0x40000000 0x30000000>;
ranges = <0x0 0x0 0x10000000 0x10000000
0x1 0x0 0x40000000 0x10000000
0x2 0x0 0x50000000 0x10000000
0x3 0x0 0x60000000 0x10000000>;
clocks = <&mck>;
nand_controller: nand-controller {
compatible = "atmel,sama5d3-nand-controller";
atmel,nfc-sram = <&nfc_sram>;
atmel,nfc-io = <&nfc_io>;
ecc-engine = <&pmecc>;
#address-cells = <2>;
#size-cells = <1>;
ranges;
nand@3 {
reg = <0x3 0x0 0x800000>;
atmel,rb = <0>;
/*
* Put generic NAND/MTD properties and
* subnodes here.
*/
};
};

* Denali NAND controller
Required properties:
- compatible : should be "denali,denali-nand-dt"
- compatible : should be one of the following:
"altr,socfpga-denali-nand" - for Altera SOCFPGA
- reg : should contain registers location and length for data and reg.
- reg-names: Should contain the reg names "nand_data" and "denali_reg"
- interrupts : The interrupt number.
- dm-mask : DMA bit mask
The device tree may optionally contain sub-nodes describing partitions of the
address space. See partition.txt for more detail.
