During PM resume and suspend do not ignore the return value of
spi_master_suspend() or spi_master_resume(). Instead pass it further.

This patch adds support for propagation of setup of clock's parent one level

This feature is helpful when a driver changes topology of its clocks using
clk_set_parent(). The problem occurs when on one platform/SoC driver's clock

The HDMIPHY (physical interface) is controlled by a single
bit in a power controller's regiter. It was implemented
as clock. It was a simple but effective hack.
This patch makes HDMI driver to control HDMIPHY via PHY interface.
