Make the OS timer registers have IOMEM like properities so they can be passed to readl_relaxed/writel_relaxed() et.al. rather than being straight volatile dereferences. Add linux/io.h includes where required. linux/io.h includes added to arch/arm/mach-sa1100/cpu-sa1100.c, arch/arm/mach-sa1100/jornada720_ssp.c, arch/arm/mach-sa1100/leds-lart.c drivers/input/touchscreen/jornada720_ts.c, drivers/pcmcia/sa1100_shannon.c from Arnd. This fixes these warnings: arch/arm/mach-sa1100/time.c: In function 'sa1100_timer_init': arch/arm/mach-sa1100/time.c:104: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type arch/arm/mach-pxa/time.c: In function 'pxa_timer_init': arch/arm/mach-pxa/time.c:126: warning: passing argument 1 of 'clocksource_mmio_init' discards qualifiers from pointer target type Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
