ARM: pxa2xx: reorganize I2C files This patch moves the platform data definition from arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so it can be accessed from x86 the same way as on ARM. This change should make no functional change to the PXA code. The move is verified by building the following defconfigs: cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig pxa910_defconfig Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

[ARM] pxa: make it clear by converting MMC 'delay_detect' to millisecond delay_detect in HZ is confusing, convert it to be millisecond based. And thus remove those unnecessary call to msecs_to_jiffies() at runtime for this field. Other constants are converted assuming HZ == 100, which are basically true for those platforms. The assignment in csb726.c was incorrect, and is fixed in this patch as a result.

Update platform driver to support this feature. Another notice should be taken that: When you want to use this feature, you should not enable the keep configuration feature, for two chip select could be attached with different nand chip. The different page size and timing requirement make the keep configuration impossible. Signed-off-by: Lei Wen <leiwen@marvell.com>
