Some of the missing items I seen 1. Of_node not populated in omap_nand_platform_data structure. 2. Remove platform device creation from hwmod as GPMC DT is populating. Currently GPMC device creaing from DT & HWMOD. Also can you address how this patch series depends on mtd: nand: OMAP: ELM error correction support for BCH ecc Thanks Avinash > > 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
