* ARM: keystone: Avoid calling of_clk_init() twiceSantosh Shilimkar2013-12-161-1/+0
| | | | | | | | | | | | | | | | | | 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>
* ARM: keystone: Make PM bus ready before populating platform devicesSantosh Shilimkar2013-12-161-1/+0
| | | | | | | | | | | | | | 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.

* ARM: keystone: fix PM domain initcall to be keystone onlyKevin Hilman2013-10-141-0/+12
| | | | | | | | initcalls need to have platform specific checks so they are not run in multi-platform builds. Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Kevin Hilman <khilman@linaro.org>
* ARM: keystone: add PM domain support for clock managementSantosh Shilimkar2013-10-101-0/+70
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.
