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>
