* ARM: OMAP2+: Remove legacy gpmc-nand.cLadislav Michl2017-02-281-154/+0
| | | | | | | | | | | | | This code is no longer used and can be removed as we are using device tree. Removing this code also removes a dependency between drivers/mtd and arch/arm/mach-omap2 making furhter driver changes easier.

* ARM OMAP2+ GPMC: calculate GPMCFCLKDIVIDER based on WAITMONITORINGTIMERobert ABEL2015-03-061-8/+10
| | | | | | | | | | | | | | | The WAITMONITORINGTIME is expressed as a number of GPMC_CLK clock cycles, even though the access is defined as asynchronous, and no GPMC_CLK clock is provided to the external device. Still, GPMCFCLKDIVIDER is used as a divider for the GPMC clock, so it must be programmed to define the correct WAITMONITORINGTIME delay. Calculate GPMCFCLKDIVIDER independent of gpmc,sync-clk-ps in DT for pure asynchronous accesses, i.e. both read and write asynchronous.

* ARM: OMAP2+: Prepare to move GPMC to drivers by platform data headerTony Lindgren2014-11-201-2/+1
| | | | | | | | | | | | | | | | | | We still need to support platform data for omap3 until it's booting in device tree only mode. So let's add platform_data/omap-gpmc.h for that, and a minimal linux/omap-gpmc.h for the save and restore used by the PM code. Let's also keep a minimal mach-omap2/gpmc.h still around to avoid churn on the board-*.c files. Once omap3 boots in device tree only mode, we can drop mach-omap2/gpmc.h and we can make the data structures in platform_data/omap-gpmc.h private to the GPMC driver. Note that we can now also remove gpmc-nand.h and gpmc-onenand.h. Cc: Arnd Bergmann <arnd@arndb.de> Acked-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* mtd: nand: omap: Revert to using software ECC by defaultRoger Quadros2014-08-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | For v3.12 and prior, 1-bit Hamming code ECC via software was the default choice. Commit c66d039197e4 in v3.13 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND filesystems created in v3.12 and prior to be unusable in v3.13 and later. So revert back to using software ECC by default if an ECC scheme is not explicitely specified. This defect can be observed on the following boards during legacy boot -omap3beagle -omap3touchbook -overo -am3517crane -devkit8000 -ldp -3430sdp Signed-off-by: Roger Quadros <rogerq@ti.com> Tested-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

This commit should have updated the GPMC NAND documentation (Documentation/devicetree/bindings/mtd/gpmc-nand.txt) to list the property "gpmc,device-nand" as a required property and also updated the example. However, this property is redundant and not needed because the GPMC child device node for NAND is called "nand". Therefore, remove this property.

This moves the configuration of some GPMC options outside the nand_gpmc_retime() because these options should only need to be set once regardless of whether the gpmc timing is changing dynamically at runtime. The programming of where the wait-pin is also moved slightly, but this will not have any impact to existing devices as no boards are currently setting the dev_ready variable.

* ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren2012-09-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
