clk: add CLK_SET_RATE_NO_REPARENT flag

2013-08-19T19:27:17+00:00

Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes
being reparented during clk_set_rate.

To avoid breaking existing platforms, all callers of clk_register_mux()
are adjusted to pass the new flag. Platform maintainers are encouraged
to remove the flag if they wish to allow mux reparenting on set_rate.

clk: mxs: remove the use of mach level IO accessor

2013-04-01T08:30:04+00:00

It removes the use of mach level IO accessor __mxs_setl/clrl, and hence
removes mach header inclusion from clock driver.

clk: mxs: get base address from device tree

2013-04-01T08:30:04+00:00

Instead of using the static definitions, get clkctrl and digctl base
addresses with mapping from device tree.

Use macro on variable is not nice, but it's done here to save huge
pointless diff stat.

ARM: mxs: look up timrot clock from device tree

2013-04-01T08:30:02+00:00

Change call clk_get_sys() to of_clk_get() to look up timrot clock from
device tree, so that the clk_register_clkdev() call for timrot can be
saved in clock driver.

ARM: mxs: use CLKSRC_OF helper to initialize timer

2013-04-01T08:30:01+00:00

Select CLKSRC_OF and use clocksource_of_init() to initialize timer, so
that the call to mxs_timer_init() in clock driver can be removed.

Pull ARM SoC-specific updates from Arnd Bergmann:
 "This is a larger set of new functionality for the existing SoC
  families, including:

   - vt8500 gains support for new CPU cores, notably the Cortex-A9 based
     wm8850

   - prima2 gains support for the "marco" SoC family, its SMP based
     cousin

   - tegra gains support for the new Tegra4 (Tegra114) family

   - socfpga now supports a newer version of the hardware including SMP

   - i.mx31 and bcm2835 are now using DT probing for their clocks

   - lots of updates for sh-mobile

   - OMAP updates for clocks, power management and USB

   - i.mx6q and tegra now support cpuidle

   - kirkwood now supports PCIe hot plugging

   - tegra clock support is updated
