Hi, Basic gpmc driver conversion series. Driver that is now created out of gpmc code is a simple one, it handles tasks that were earlier executed by gpmc_init. Now instead of relying on cpu_is_* checks, it obtains resources and clk handle in the standard Linux way. The existing gpmc interface works as was without this series. HWMOD patch also has been brought into this series back with v7 series As this creates only a basic driver, further gpmc driver work can be based over this, while having a driver first in place. This series is based on l-o/testing-cleanup as on 5-Sep-12, i.e. over commit, e3a5c14 ARM: OMAP1: Move SoC specific headers from plat to mach for omap1 per Tony's suggestion. It is available @git://gitorious.org/x0148406-public/linux-kernel.git gpmc-drv-v8 This series has been tested on omap3evm (rev G). GPMC (General Purpose Memory Controller) in brief: GPMC is an unified memory controller dedicated to interfacing external memory devices like Asynchronous SRAM like memories and application specific integrated circuit devices. Asynchronous, synchronous, and page mode burst NOR flash devices NAND flash Pseudo-SRAM devices GPMC details can be referred in AM335X Technical Reference Manual @ http://www.ti.com/lit/pdf/spruh73 Regards Afzal v8: Use feature flag to decide whether wr_access and wr_data_mux_bus timings has to be configured (PATCH 3/3) v7: Create a simple driver that gets resources & clk the standard Linux way Pull in HMWOD patch back into this series v6: Capability flag added that stores features based on revision Macros used for finding revision Return value from memory setup function corrected Comments added to clarify handling of device type, size Bool type time setting patch removed as has been taken care in [2] Handle variable number of waitpin Warn if driver is unable to configure interrupt Enhance some of commit messages Handle shared writeprotect case Fix a bug in gpmc_create_device Get clk from hwmod Remove unwanted code v5: Make this a purely driver conversion series, i.e. gpmc-mtd interactions has been made as a separate series, so is adding hwmod entry for OMAP2/3. And modifying gpmc peripheral platform initialization has been separated out of this series, so is migrating boards to use new driver interface. GPMC driver conversion which was done in a few patches in v4 has been tranformed to series of small patches. Also care has been taken care that old interface will not break with any of these patches, so both interfaces can coexist. This helps in converting boards one-by-one gradually. Acquiring CS has been thrown out. And conclusive comments on v4 has been addressed. v4: Handle wait pin (except for interrupts), enhance configuration & timing interface of GPMC to take care of all boards. Dynamic allocation of interrupt instead of static. Convert remaining peripherals to work with GPMC driver. Handle acquiring NAND CS#, adapt to HWMOD, update HWMOD OMAP2/3 entries, other minor commenst on v3. v3: Single device structure passed from platform for peripherals using multiple CS instead of using multiple device structure having a few redundant data, handle interrupts, GPMC NAND handling by GPMC NAND driver instead of GPMC driver v2: Avoid code movement that kept similar code together (for easy review) Afzal Mohammed (3): ARM: OMAP2/3: hwmod data: add gpmc ARM: OMAP2+: gpmc: Adapt to HWMOD ARM: OMAP2+: gpmc: minimal driver support arch/arm/mach-omap2/gpmc.c | 197 +++++++++++++++----- arch/arm/mach-omap2/omap_hwmod_2420_data.c | 18 ++ arch/arm/mach-omap2/omap_hwmod_2430_data.c | 18 ++ arch/arm/mach-omap2/omap_hwmod_2xxx_ipblock_data.c | 44 +++++- arch/arm/mach-omap2/omap_hwmod_3xxx_data.c | 54 ++++++ arch/arm/mach-omap2/omap_hwmod_common_data.h | 1 + arch/arm/mach-omap2/prcm-common.h | 2 + 7 files changed, 284 insertions(+), 50 deletions(-) -- 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
