The main goal is to get rid of the mach/ headers dependency. At the same time, it introduces proper probing and locking (using a regmap) for the watchdog driver. This is based on 4.0-rc1 and will have two merge conflicts with my cleanup #1 in mach-at91/at91rm9200.c It also needs this patch to probe the watchdog properly: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-March/327274.html Changes in v5: - Documented the watchdog compatible - Switched to simple-mfd to probe the system timer subnodes - Selected ATMEL_ST from mach-at91/Kconfig instead of using def_bool SOC_AT91RM9200 - Reordered the atmel-st probe cleanup and its move to driver/clocksource - Added a patch to replace setup_irq by request_irq - Merged the reset handling in the watchdog timer as we are using the watchdog anyway to reset the board. - Used a simple space after a #define for registers Changes in v4: - Added MODULE_* metadata in at91rm9200-reset - Proper copyright in at91rm9200-reset - Use BIT() in atmel-st.h - changed MODULE_ALIAS in at91rm9200_wdt.c Changes in v3: - stop using an mfd and get the syscon directly from the watchdog driver - introduce a proper reset driver to handle reset Changes in v2: - cleaned up more includes in the watchdog driver - stop using if OF when selecting CLKSRC_OF - stop initializing .owner Alexandre Belloni (10): ARM: at91/dt: declare atmel,at91rm9200-st as a syscon mfd: syscon: Add atmel system timer registers definition watchdog: at91rm9200: use the system timer syscon watchdog: at91rm9200: implement restart handler ARM: at91: at91rm9200: remove deprecated arm_pm_restart ARM: at91: properly initialize timer ARM: at91: time: move the system timer driver to drivers/clocksource clocksource: atmel-st: use syscon/regmap clocksource: atmel-st: remove mach/hardware dependency ARM: at91: remove useless include .../devicetree/bindings/arm/atmel-at91.txt | 4 +- arch/arm/boot/dts/at91rm9200.dtsi | 6 +- arch/arm/mach-at91/Kconfig | 1 + arch/arm/mach-at91/Makefile | 2 +- arch/arm/mach-at91/at91rm9200.c | 19 ---- arch/arm/mach-at91/generic.h | 3 - arch/arm/mach-at91/include/mach/at91_st.h | 61 ----------- drivers/clocksource/Kconfig | 4 + drivers/clocksource/Makefile | 1 + .../clocksource/timer-atmel-st.c | 115 ++++++++------------- drivers/watchdog/Kconfig | 2 +- drivers/watchdog/at91rm9200_wdt.c | 61 +++++++++-- include/linux/mfd/syscon/atmel-st.h | 49 +++++++++ 13 files changed, 164 insertions(+), 164 deletions(-) delete mode 100644 arch/arm/mach-at91/include/mach/at91_st.h rename arch/arm/mach-at91/at91rm9200_time.c => drivers/clocksource/timer-atmel-st.c (74%) create mode 100644 include/linux/mfd/syscon/atmel-st.h -- 2.1.0
