[Resending +devicetree-discuss, +Rob, +Grant] This is a series of patches to support GPMC peripherals on OMAP boards. Depends on Linus' master + omap-next (branch omap-for-v3.8/cleanup-headers-gpmc) The only supported peripheral for now is NAND, but other types would be easy to add. Version 2 addresses details pointed out by Jon Hunter, Afzal Mohammed and Rob Herring: - add "reg" and "ti,hwmod" properties to Documentation - use generic of_mtd functions and the property names defined by them, namely "nand-bus-width" and "nand-ecc-mode" - reduce the default register space size in the Documentation to 8K, as found in the hwmod code - switch to a DT layout based on ranges and address translation. Although this property is not currently looked at as long as the handling code still uses the runtime calculation methods, we now have these values in the bindings, eventually allowing us to switch the implementation with less pain. Version 3 includes fixes pointed out by Jon Hunter: - better documentation of the 'ranges' property to describe the fact that it's representing the CS lines - GPMC_CS_CONFIGx -> GPMC_CONFIGx in comments - drop interrupt-parent from example bindings - add of_node_put() at the end of the child iteration Version 4 fixes compilation for !CONFIG_MTD_NAND and includes more details from Jon Hunter and Avinash, Philip: - Add "num-cs" and "num-waitpins" properties, which will eventually be used to get rid of GPMC_CS_NUM - Better description of generic nand DT properties - Dropped patch 3/4 as an equivalent fix was already merged - Added ti,nand-ecc-use-elm property Version 5 with regards to Avinash, Philip and Peter Korsgaard: - Re-add accidentially forgotten Documentation/devicetree/bindings/bus/ti-gpmc.txt - Rename "software" ecc mode to "sw" - Initialize gpmc_nand_data->is_elm_used to 'true' rather than 1 - Drop ti,nand-ecc-use-elm binding in favor of a new ecc mode named "bch8-am335xrbl-compatible" - Add two more patches for section mismatch fixups Daniel Mack (4): mtd: omap-nand: pass device_node in platform data ARM: OMAP: gpmc-nand: drop __init annotation ARM: OMAP: gpmc: enable hwecc for AM33xx SoCs ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND Documentation/devicetree/bindings/bus/ti-gpmc.txt | 76 +++++++++ .../devicetree/bindings/mtd/gpmc-nand.txt | 81 +++++++++ arch/arm/mach-omap2/gpmc-nand.c | 15 +- arch/arm/mach-omap2/gpmc.c | 181 ++++++++++++++++++++- drivers/mtd/nand/omap2.c | 4 +- 5 files changed, 348 insertions(+), 9 deletions(-) create mode 100644 Documentation/devicetree/bindings/bus/ti-gpmc.txt create mode 100644 Documentation/devicetree/bindings/mtd/gpmc-nand.txt -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
