Pull MTD updates from Brian Norris: "First cycle with Boris as NAND maintainer! Many (most) bullets stolen from him. Generic: - Migrated NAND LED trigger to be a generic MTD trigger NAND: - Introduction of the "ECC algorithm" concept, to avoid overloading the ECC mode field too much more - Replaced the nand_ecclayout infrastructure with something a little more flexible (finally!) and future proof - Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some of this into their own tree as well - Prepare the sunxi NAND driver to receive DMA support - Handle bitflips in erased pages on GPMI revisions that do not support this in hardware. SPI NOR: - Start using the spi_flash_read() API for SPI drivers that support it (i.e., SPI drivers with special memory-mapped flash modes) And other small scattered improvments" * tag 'for-linus-20160523' of git://git.infradead.org/linux-mtd: (155 commits) mtd: spi-nor: support GigaDevice gd25lq64c mtd: nand_bch: fix spelling of "probably" mtd: brcmnand: respect ECC algorithm set by NAND subsystem gpmi-nand: Handle ECC Errors in erased pages Documentation: devicetree: deprecate "soft_bch" nand-ecc-mode value mtd: nand: add support for "nand-ecc-algo" DT property mtd: mtd: drop NAND_ECC_SOFT_BCH enum value mtd: drop support for NAND_ECC_SOFT_BCH as "soft_bch" mapping mtd: nand: read ECC algorithm from the new field mtd: nand: fsmc: validate ECC setup by checking algorithm directly mtd: nand: set ECC algorithm to Hamming on fallback staging: mt29f_spinand: set ECC algorithm explicitly CRIS v32: nand: set ECC algorithm explicitly mtd: nand: atmel: set ECC algorithm explicitly mtd: nand: davinci: set ECC algorithm explicitly mtd: nand: bf5xx: set ECC algorithm explicitly mtd: nand: omap2: Fix high memory dma prefetch transfer mtd: nand: omap2: Start dma request before enabling prefetch mtd: nandsim: add __init attribute mtd: nand: move of_get_nand_xxx() helpers into nand_base.c ...

mtd: nand: move of_get_nand_xxx() helpers into nand_base.c

2016-05-05T21:52:00Z

Now that all drivers go through nand_set_flash_node() to parse the generic NAND properties, we can move all of_get_nand_xxx() helpers in to nand_base.c, make them static and remove of_mtd.c and of_mtd.h. Signed-off-by: Boris Brezillon

of, numa: Add NUMA of binding implementation.

2016-04-15T17:06:08Z

Add device tree parsing for NUMA topology using device "numa-node-id" property in distance-map and cpu nodes. This is a complete rewrite of a previous patch by: Ganapatrao Kulkarni Signed-off-by: David Daney Acked-by: Rob Herring Signed-off-by: Will Deacon

of: clean-up unnecessary libfdt include paths

2015-06-05T01:16:47Z

With the libfdt include fixups to use "" instead of <> in the latest dtc import in commit 4760597 (scripts/dtc: Update to upstream version 9d3649bd3be245c9), it is no longer necessary to add explicit include paths to use libfdt. Remove these across the kernel.

dt: OF_UNITTEST make dependency broken

2015-03-25T05:43:44Z

If CONFIG_OF_UNITTEST=y then a kernel image make will always cause .version to be incremented, even if there are not source changes. This is caused by a lack of dependency tracking and checking for drivers/of/unittest-data/testcases.dtb.o. Signed-off-by: Frank Rowand Signed-off-by: Rob Herring

of/overlay: Introduce DT overlay support

2014-11-24T22:25:10Z

Overlays are a method to dynamically modify part of the kernel's device tree with dynamically loaded data. Add the core functionality to parse, apply and remove an overlay changeset. The core functionality takes care of managing the overlay data format and performing the add and remove. Drivers are expected to use the overlay functionality to support custom expansion busses commonly found on consumer development boards like the BeagleBone or Raspberry Pi. The overlay code uses CONFIG_OF_DYNAMIC changesets to perform the low level work of modifying the devicetree. Documentation about internal and APIs is provided in Documentation/devicetree/overlay-notes.txt v2: - Switch from __of_node_alloc() to __of_node_dup() - Documentation fixups - Remove 2-pass processing of properties - Remove separate ov_lock; just use the DT mutex. v1: - Drop delete capability using '-' prefix. The '-' prefixed names are valid properties and nodes and there is no need for it just yet. - Do not update special properties - name & phandle ones. - Change order of node attachment, so that the special property update works.

of/unittest: Rename selftest.c to unittest.c

2014-11-04T16:43:07Z

This is unit testing code. It should use that name because it makes more sense than 'selftest'. Rename the files to match and rename the config variable. Signed-off-by: Grant Likely

of: Introduce Device Tree resolve support.

2014-10-04T20:24:26Z

Introduce support for dynamic device tree resolution. Using it, it is possible to prepare a device tree that's been loaded on runtime to be modified and inserted at the kernel live tree.

Adding selftest testdata dynamically into live tree

2014-07-25T06:18:13Z

This patch attaches selftest's device tree data (required by /drivers/of/selftest.c) dynamically into live device tree. First, it links selftest device tree data into the kernel image and then iterates over all the nodes and attaches them into the live tree. Once the testcases are complete, it removes the data attached. This patch will remove the manual process of addition and removal of selftest device tree data into the machine's dts file. Tested successfully with current selftest's testcases. Signed-off-by: Gaurav Minocha [glikely: Removed ability to build as a module and fixed no-devicetree bug] Signed-off-by: Grant Likely
