Drop AT91_TIMER_HZ as this can be handled using HZ_FIXED. Initial help message was: On AT91rm9200 chips where you're using a system clock derived from the 32768 Hz hardware clock, this tick rate should divide it exactly: use a power-of-two value, such as 128 or 256, to reduce timing errors caused by rounding.

Third batch of cleanup for 4.1: - System Timer (ST) for at91rm9200 re-work (syscon/regmap): - watchdog - restart handler - timer as a proper clocksource => remove mach dependency + cleanup

Nicolas Ferre authored
Second batch of cleanup for 4.1: - remove unused matrix header files - dbgu + chip identification: new driver for SoC detection this allow to remove all additional io mapping - remove old non-standard AT91 setup code

First batch of cleanup for 4.1: - little phy fixup that is not needed anymore - hudge cleanup of the PM code: - removal of "use slow clock" option => always use this for suspend to RAM - quicker suspend as the asm function is copied only once to SRAM - use of the same asm function for "standby" and "mem" types of suspend actions - adaptation to the ARMv7 processors -

Second fixes batch for AT91 on 4.0: - little fix for !MMU debug: may also help for randconfig - fix of 2 errors in LCD clock definitions - in PM code, not writing the key leads to not execute the action

The system timer register range is used to handle three different functionalities: Periodic Interval Timer, Real Time Timer and watchdog. Declare it as a syscon to be able to get a regmap. Also declare it as a simple-mfd and its watchdog subnode. Finally, document the watchdog compatible string. Signed-off-by:

The mach/io.h header on at91 is used to support a nonstandard I/O space window for the cf card driver. This changes the driver to use pci_ioremap_io in order to have the standard location, and then removes the custom mach/io.h.
