ARM: OMAP2+: gpmc-onenand: propagate error on initialization failure

2018-01-17T17:55:25Z

[ Upstream commit 7807e086a2d1f69cc1a57958cac04fea79fc2112 ] gpmc_probe_onenand_child returns success even on gpmc_onenand_init failure. Fix that. Signed-off-by: Ladislav Michl Acked-by: Roger Quadros Signed-off-by: Tony Lindgren Signed-off-by: Sasha Levin

ARM OMAP2+ GPMC: calculate GPMCFCLKDIVIDER based on WAITMONITORINGTIME

2015-03-06T10:39:48Z

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 header

2014-11-20T20:11:25Z

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 Acked-by: Roger Quadros Signed-off-by: Tony Lindgren
