Hi, GPMC driver conversion patch series. Some peripherals has GPMC helper functions, these has been modified to cater to the needs of GPMC driver. All the boards using GPMC has been adapted to use the new GPMC driver. GPMC HWMOD entry for OMAP2/3 has been added. On OMAP3, kernel does spit "omap_hwmod: gpmc: cannot be enabled for reset (3)", but peripherals connected via GPMC are working. Really shaky about OMAP2 GPMC HWMOD entry. Would be helpful if someone can help me in resolving warning on OMAP3 & verify whether OMAP2 entry is proper. The series adapts to HWMOD. Drivers, NAND & OneNAND of OMAP has been modified to make use of GPMC changes & cleaned up the now unnecessary exported symbol usages. This series has been made on top of, 5e136da Linux-omap rebuilt: Updated to -rc5, A patch by Javier Martinez Canillas <javier@xxxxxxxxxxxx>, OMAP3: igep0020: Add support for Micron NAND Flash storage memory, has also been incorporated into the series as this was necessary for igep0020 board. This has been tested on omap3 evm (SMSC911x) & beagle board (NAND) I would need help to get these changes tested on other boards using GPMC. Expected problematic boards are those having OMAP2xxx SoCs, apollon board. In the case of apollon, in addition to it being OMAP2xxx, it was modified to use gpmc_smc91x_init instead of directly writing to configuration registers. Additional features that currently boards in mainline does not make use of like, waitpin interrupt handling, changes to leverage revision 6 IP differences has not been incorporated. GPMC driver now provides NAND driver with GPMC-NAND registers so that OMAP NAND driver can handle those by itself instead of using exported symbols. Acquiring CS for NAND has also been incorporated, it has been made as a separate patch as it is felt that this should probably go away, explained in the relevant patch. 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 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) TODO: Cleanup Regards Afzal Afzal Mohammed (38): ARM: OMAP2+: gpmc: driver conversion ARM: OMAP2+: gpmc: Adapt to HWMOD ARM: OMAP2+: gpmc: register details for nand driver ARM: OMAP2+: gpmc: Acquire NAND CS value ARM: OMAP2+: nand: create platform data structure ARM: OMAP2+: onenand: return value in init function ARM: OMAP2+: gpmc-nand: Adapt to use gpmc driver ARM: OMAP2+: gpmc-onenand: Adapt to use gpmc driver ARM: OMAP2+: flash: Adapt to gpmc driver ARM: OMAP2+: gpmc-smsc911x: Adapt to use gpmc driver ARM: OMAP2+: gpmc-smc91x: Adapt to use gpmc driver ARM: OMAP2+: gpmc-tusb6010: Adapt to gpmc driver ARM: OMAP3: hwmod data: add gpmc ARM: OMAP2xxx: hwmod data: add gpmc mtd: nand: omap2: obtain memory from resource mtd: nand: omap2: use gpmc provided irqs mtd: nand: omap2: handle nand on gpmc mtd: onenand: omap: obtain memory from resource ARM: OMAP2+: board omap3evm: gpmc driver adaptation ARM: OMAP2+: board omap3beagle: gpmc driver adaptation ARM: OMAP2+: board apollon: gpmc driver adaptation ARM: OMAP2+: board h4: gpmc driver adaptation ARM: OMAP2+: board 3630sdp: gpmc driver adaptation ARM: OMAP2+: board 3430sdp: gpmc driver adaptation ARM: OMAP2+: board 2430sdp: gpmc driver adaptation ARM: OMAP2+: board cm-t3517: gpmc driver adaptation ARM: OMAP2+: board cm-t35: gpmc driver adaptation ARM: OMAP2+: board ldp: gpmc driver adaptation ARM: OMAP2+: board n8x0: gpmc driver adaptation ARM: OMAP2+: board omap3logic: gpmc driver adaptation ARM: OMAP2+: board omap3pandora: gpmc driver adaptation ARM: OMAP2+: board omap3stalker: gpmc driver adaptation ARM: OMAP2+: board omap4pcm049: gpmc driver adaptation ARM: OMAP2+: board overo: gpmc driver adaptation ARM: OMAP2+: board rm680: gpmc driver adaptation ARM: OMAP2+: board rx51: gpmc driver adaptation ARM: OMAP2+: board zoom-debugboard: gpmc driver adaptation ARM: OMAP2+: board igep0020: gpmc driver adaptation Javier Martinez Canillas (1): OMAP3: igep0020: Add support for Micron NAND Flash storage memory arch/arm/mach-omap2/board-2430sdp.c | 44 +- arch/arm/mach-omap2/board-3430sdp.c | 18 +- arch/arm/mach-omap2/board-3630sdp.c | 23 +- arch/arm/mach-omap2/board-apollon.c | 152 +-- arch/arm/mach-omap2/board-cm-t35.c | 21 +- arch/arm/mach-omap2/board-cm-t3517.c | 10 +- arch/arm/mach-omap2/board-devkit8000.c | 6 +- arch/arm/mach-omap2/board-flash.c | 160 ++-- arch/arm/mach-omap2/board-flash.h | 36 +- arch/arm/mach-omap2/board-h4.c | 130 +-- arch/arm/mach-omap2/board-igep0020.c | 99 +- arch/arm/mach-omap2/board-ldp.c | 26 +- arch/arm/mach-omap2/board-n8x0.c | 18 +- arch/arm/mach-omap2/board-omap3beagle.c | 22 +- arch/arm/mach-omap2/board-omap3evm.c | 14 +- arch/arm/mach-omap2/board-omap3logic.c | 13 +- arch/arm/mach-omap2/board-omap3pandora.c | 11 +- arch/arm/mach-omap2/board-omap3stalker.c | 13 +- arch/arm/mach-omap2/board-omap3touchbook.c | 6 +- arch/arm/mach-omap2/board-omap4pcm049.c | 13 +- arch/arm/mach-omap2/board-overo.c | 32 +- arch/arm/mach-omap2/board-rm680.c | 10 +- arch/arm/mach-omap2/board-rx51-peripherals.c | 17 +- arch/arm/mach-omap2/board-zoom-debugboard.c | 47 +- arch/arm/mach-omap2/board-zoom.c | 5 +- arch/arm/mach-omap2/common-board-devices.c | 46 - arch/arm/mach-omap2/common-board-devices.h | 1 - arch/arm/mach-omap2/gpmc-nand.c | 84 +- arch/arm/mach-omap2/gpmc-onenand.c | 111 +-- arch/arm/mach-omap2/gpmc-smc91x.c | 87 +- arch/arm/mach-omap2/gpmc-smsc911x.c | 59 +- arch/arm/mach-omap2/gpmc.c | 980 +++++++++++++++++--- 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 | 41 + arch/arm/mach-omap2/omap_hwmod_3xxx_data.c | 52 ++ arch/arm/mach-omap2/omap_hwmod_common_data.h | 1 + arch/arm/mach-omap2/prcm-common.h | 2 + arch/arm/mach-omap2/usb-tusb6010.c | 177 ++-- arch/arm/plat-omap/include/plat/gpmc-smc91x.h | 10 +- arch/arm/plat-omap/include/plat/gpmc-smsc911x.h | 9 +- arch/arm/plat-omap/include/plat/gpmc.h | 110 ++- arch/arm/plat-omap/include/plat/nand.h | 10 +- arch/arm/plat-omap/include/plat/onenand.h | 7 +- drivers/mtd/nand/omap2.c | 296 ++++-- drivers/mtd/onenand/omap2.c | 29 +- include/linux/usb/musb.h | 4 +- 47 files changed, 2110 insertions(+), 988 deletions(-) -- 1.7.10 -- 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
