Santosh Shilimkar	7fef917ba8	ARM: keystone: Avoid calling of_clk_init() twice With commit `4178bac4f` {ARM: call of_clk_init from default time_init handler}, of_clk_init() is always called on machines using default time_init handler. So drop the of_clk_init() from keystone code to avoid below boot errors because of double call. _of_pll_clk_init: error initializing pll mainpllclk _of_pll_clk_init: error initializing pll papllclk _of_pll_clk_init: error initializing pll ddr3apllclk _of_pll_clk_init: error initializing pll ddr3bpllclk _of_pll_clk_init: error initializing pll armpllclk Reported-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>	2013-12-16 16:03:36 -05:00
Santosh Shilimkar	8308a78db8	ARM: keystone: Make PM bus ready before populating platform devices Keystone PM bus makes use of generic PM clock core backend. Since generic PM clock core uses platform bus notifiers to track events like ADD_DEVICE/DEL_DEVICE and to fill clock lists per each device, we need to initialise Keystone PM domains before the platform devices have been created. Hence, fix it by moving keystone_pm_runtime_init() before platform devices have been populated.

Kevin Hilman	8620d2c536	ARM: keystone: fix PM domain initcall to be keystone only initcalls need to have platform specific checks so they are not run in multi-platform builds.

Santosh Shilimkar	fc20ffe121	ARM: keystone: add PM domain support for clock management Add runtime PM core support to Keystone SOCs by using the pm_clk infrastructure of the PM core. Patch is based on Kevin's pm_domain work on DaVinci SOCs. Keystone SOC doesn't have depedency to enable clocks in early in the boot and hence the clock and PM domain initialisation is done at subsys_init() level.
