Commit 2ee619f9487c2acc1efdf2c78e68e2bd51b635fa upstream. Make the TMU clocksource driver mark its device as "always on" using pm_genpd_dev_always_on() to protect it from surprise power removals and make sh7372_add_standard_devices() add TMU devices on sh7372 to the A4R power domain so that their "always on" flags are taken into account as appropriate.

The i8253 clockevent & clocksource driver uses PIT_LATCH
except for two cases where it uses LATCH:
1)
/* VIA686a test code... reset the latch if count > max + 1 */
if (count > LATCH) {
LATCH is based on CLOCK_TICK_RATE which is defined as
PIT_TICK_RATE on x86 so this should just be the later.
2)
...
switch (mode) {
case CLOCK_EVT_MODE_PERIODIC:
/* binary, mode 2, LSB/MSB, ch 0 */
outb_p(0x34, PIT_MODE);
outb_p(LATCH & 0xff , PIT_CH0); /* LSB */
outb_p(LATCH >> 8 , PIT_CH0); /* MSB */
...
MIPS and ARM are the only other arches that use this driver. In
the MIPS case CLOCK_TICK_RATE is defined as the same value as
PIT_TICK_RATE. For ARM, the only machine that uses it is
Footbridge which has a totally bogus CLOCK_TICK_RATE according
to the comments. Furthermore, the clockevent_i8253_init()
initializes the clockevent with PIT_TIC_RATE, so there's
no reason to use the generic LATCH.
This is part of work to remove and depecrate the global
CLOCK_TICK_RATE symbol.

The acpi_pm clocksource driver uses CLOCK_TICK_RATE which is defined as PIT_TICK_RATE on x86. This patch cleans it up to just use the later so that CLOCK_TICK_RATE can be depecrated. Signed-off-by: Deepak Saxena <dsaxena@linaro.org> Signed-off-by: John Stultz <john.stultz@linaro.org>
