> This patch set cleans up the system timer driver.
> 
> 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

I'm okay with the whole series:
Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com>

But anyway, I'm waiting for a couple of more Ack.

Thanks, bye.
