2012-10-15ARM: OMAP2+: gpmc: localize gpmc headerAfzal Mohammed
Requirement of gpmc header outside of mach-omap2 has been cutoff, move gpmc header file in plat-omap folder to local mach-omap2 folder Objective - common zImage participation of omap Signed-off-by: Afzal Mohammed <afzal@ti.com>
2012-10-15ARM: OMAP2+: nand: bch capability checkAfzal Mohammed
Capability of bch schemes could be discovered using soc revision checks. If soc revision indicates that selected ecc scheme is not supported bail out. Signed-off-by: Afzal Mohammed <afzal@ti.com>
2012-10-15ARM: OMAP2+: nand: header cleanupAfzal Mohammed
For common arm zImage existing nand header file in platform specific location was moved to generic platform data location, but it contained more than platform data, remove it. New local header has been created for exposing functions. Also move gpmc-nand platform data to platform header meant for nand from gpmc header file Signed-off-by: Afzal Mohammed <afzal@ti.com>
2012-09-19ARM: omap: move platform_data definitionsArnd Bergmann
Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories.

2012-09-13ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren
As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

2012-09-13Merge tags 'omap-devel-gpmc-fixed-for-v3.7' and 'cleanup-omap-tags-for-v3.7' ↵Tony Lindgren
into cleanup-sparseirq Changes for GPMC (General Purpose Memory Controller) that take it closer for being just a regular device driver. Remove the ancient omap specific atags that are no longer needed. At some point we were planning to pass the bootloader information with custom atags that did not work out too well. There's no need for these any longer as the kernel has been booting fine without them for quite some time. And Now we have device tree support that can be used instead.

2012-08-30ARM: OMAP2+: gpmc-nand: Modify Interrupt handlingAfzal Mohammed
Now GPMC provides its client with interrupts that can be handled using the standard interrupt API. Modify GPMC NAND setup to work with it. Also disable write protect in GPMC code, so that NAND driver can be ignorant of GPMC configuration. Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-08-30ARM: OMAP2+: gpmc-nand: update resource with memoryAfzal Mohammed
Currently omap nand driver uses a field in platform data - phys_base for passing the address space allocated by gpmc for nand. Use struct resource instead. With this change omap nand driver has to get address space from memory resource. This helps in smooth migration of gpmc to driver.

2012-08-30ARM: OMAP2+: gpmc-nand: update gpmc-nand regsAfzal Mohammed
GPMC has NAND registers, update nand platform data with those details so that NAND driver can configure those by itself instead of using exported symbols. Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-02-24ARM: OMAP: Remove plat/io.h by splitting it into mach/io.h and mach/hardware.hTony Lindgren
This is needed to minimize io.h so the SoC specific io.h for ARMs can removed. Note that minimal driver changes for DSS and RNG are needed to include cpu.h for SoC detection macros.

2011-06-29omap: cleanup NAND platform dataGrazvydas Ignotas
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and 'dma_channel' are never referenced by the NAND driver, yet various board files are initializing those fields. This is both incorrect and confusing, so remove them. This allows to get rid of a global variable in gpmc-nand.c. This also corrects an issue where some boards are trying to pass NAND 16bit flag through .options, but the driver is using .devsize instead and ignoring .options. Finally, .dev_ready is treated as a flag by the driver, so make it bool instead of a function pointer.

2010-12-21OMAP2/3: GPMC: put sync_clk value in picoseconds instead of nanosecondsAdrian Hunter
The calculations done with sync_clk are anyway in picoseconds and switching to picoseconds allows sync_clk values that are not a whole number of nanoseconds - which is sometimes the case. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2010-08-02omap3 nand: cleanup virtual address usagesSukumar Ghorai
