2012-09-20ARM: dtb: move all dtb targets to common MakefileOlof Johansson
Since the dtb targets have moved to arch/arm/boot/dts/Makefile, sweep the platforms that have had new targets added recently and move them over. While I was at it, I also made the dtb generation more generic, i.e. if the platform is enabled then all dtbs for that platform will be created.

into next/multiplatform Enable initial ARM multi-platform support for highbank, mvebu, socfpga, picoxcell, and vexpress. Multi-platform support is dependent on mach/gpio.h removal and restructuring of DEBUG_LL and dtb build rules included in this branch. This has been built for all defconfigs, and booted on highbank with all 5 platforms enabled.

2012-09-19ARM: bcm2835: add stub clock driverSimon Arlott
This patch adds a minimal stub clock driver for the BCM2835.

This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * Reworked to call clk_register_fixed_rate(), and clk_register_clkdev() rather than using static data to represent the clocks. * Moved implementation to drivers/clk/. * Modified .dev_id for UART clocks to match UART DT node names. * s/bcm2708/bcm2835/. * Modified device tree vendor prefix.

2012-09-19ARM: bcm2835: add system timerSimon Arlott
The System Timer peripheral provides four 32-bit timer channels and a single 64-bit free running counter. Each channel has an output compare register, which is compared against the 32 least significant bits of the free running counter values, and generates an interrupt. Timer 3 is used as the Linux timer. The BCM2835 also contains an SP804-based timer module. However, it apparently has significant differences from the standard SP804 IP block, and Broadcom's documentation recommends using the system timer instead. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved to drivers/clocksource/. This looks like the desired location for such code now. * Added DT binding docs. * Moved struct sys_timer bcm2835_timer into time.c to encapsulate it more. * Simplified bcm2835_time_init() to find one matching node and operate on it, rather than looping over all matching nodes. This seems more consistent with other clocksource code. * Simplified bcm2835_time_init() using of_iomap(). * Renamed struct bcm2835_timer.index to match_mask to better represent its purpose. * s/printk(PR_INFO/pr_info(/ Signed-off-by: Chris Boot <bootc@bootc.net> Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: Dom Cobley <popcornmix@gmail.com> Signed-off-by: Dom Cobley <dc4@broadcom.com> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Arnd Bergmann <arnd@arndb.de>
