OMAP: DSS2: Use PM runtime & HWMOD support
Use PM runtime and HWMOD support to handle enabling and disabling of DSS modules. Each DSS module will have get and put functions which can be used to enable and disable that module. The functions use pm_runtime and hwmod opt-clocks to enable the hardware. Acked-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
