2013-02-21Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-socLinus Torvalds1-1/+1
Pull ARM SoC device tree conversions from Arnd Bergmann: "These are device tree conversions for a number of platforms, with the intention of turning code from board files into device tree descriptions. Notable changes are: - davinci bindings for pinctrl, MTD, RTC, watchdog and i2c - nomadik bindings for all devices, removing the board files - bcm2835 bindings for mmc and i2c - tegra bindings for hdmi, keyboard, audio, as well as some updates - at91 bindings for hardware ecc and for devices on RM9200 - mxs bindings for cfa100xx - sunxi support for Miniand Hackberry board" * tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (72 commits) Revert "sunxi: a10-cubieboard: Add user LEDs to the device tree" Revert "sunxi: a13-olinuxino: Add user LED to the device tree" clk: tegra: initialise parent of uart clocks ARM: tegra: remove clock-frequency properties from serial nodes clk: tegra: fix driver to match DT binding clk: tegra: local arrays should be static clk: tegra: Add missing spinlock for hclk and pclk clk: tegra: Implement locking for super clock clk: tegra: fix wrong clock index between se to sata_cold sunxi: a13-olinuxino: Add user LED to the device tree ARM: davinci: da850 DT: add support for machine reboot ARM: davinci: da850: add wdt DT node ARM: davinci: da850: add DT node for I2C0 ARM: at91: at91sam9n12: add DT parameters to enable PMECC ARM: at91: at91sam9x5: add DT parameters to enable PMECC ARM: at91: add EMAC bindings to RM9200 DT ARM: at91: add SSC bindings to RM9200 DT ARM: at91: add MMC bindings to RM9200 DT ARM: at91: Animeo IP: enable watchdog support ARM: nomadik: fix OF compilation regression ...
2013-02-01ARM: OMAP2+: gpmc: Add device tree documentation for elm handlePhilip Avinash1-0/+4
In case ELM module available, omap2 NAND driver can opt for hardware correction method for bit flip errors in NAND flash with BCH. Hence the detection of ELM module is done through devicetree population of elm_id. This patch update device tree documentation for gpmc-nand for elm-id data population.

2013-01-28ARM: nomadik: add FSMC NANDLinus Walleij1-1/+1
This adds the FSMC NAND driver and flash partitions to the Nomadik device tree. The only compatible string accepted by this driver is currently "st,spear600-fsmc-nand" which is inappropriate for this system, so this patch adds the compatible value "stericsson,fsmc-nand" as well.

2013-01-15ARM: OMAP: gpmc: add DT bindings for GPMC timings and NANDDaniel Mack1-0/+76
This patch adds basic DT bindings for OMAP GPMC. The actual peripherals are instantiated from child nodes within the GPMC node, and the only type of device that is currently supported is NAND. Code was added to parse the generic GPMC timing parameters and some documentation with examples on how to use them. Successfully tested on an AM33xx board.

The flctl can now be probed via device tree setup in addition to the existing platform data way. SoC specific setup data is set in the .data member of the OF match, so kept within the driver itself, while board/user specific setup - like partitioning - is taken from the device tree.

2012-09-29mtd: physmap_of: Add "no-unaligned-direct-access" DT propertyStefan Roese1-0/+7
On some platforms (e.g. MPC5200) a direct 1:1 mapping may cause problems with JFFS2 usage, as the local bus (LPB) doesn't support unaligned accesses as implemented in the JFFS2 code via memcpy(). By defining "no-unaligned-direct-access", the flash will not be exposed directly to the MTD users (e.g. JFFS2) any more.

2012-08-16MTD: pxa3xx-nand: add devicetree bindingsDaniel Mack1-0/+31
This patch contains a hack to get the DMA resources of the device when probed from a devicetree node. This can be removed once a generic DMA controller framework lands. A mtd_part_parser_data is passed mtd_device_parse_register which contains a reference to the device node, so MTD partitions can be added as children.

For testing the dt work, define a dt-enabled versatile platform. This patch adds a new versatile platform for when using the device tree. Add platform and amba devices are discovered and registered by parsing the device tree. Clocks and initial io mappings are still configured statically. This patch still depends on some static platform_data for a few devices which is passed via the auxdata structure to of_platform_populate(), but it is a viable starting point until the drivers can get all configuration data out of the device tree.
