This series are based on 4.2-rc1 and provide three patches
to fix mediatek spi driver clock usage error.
spi clock manages flow:
CLK_TOP_SYSPLL3_D2 ---> CLK_TOP_SPI_SEL ---> CLK_PERI_SPI0
(source clock) (clock mux) (clock gate)
spi driver should choose source clock by clock mux, then enable clock gate.

spi: Mediatek: Document devicetree bindings update for spi bus
