[Leilk Liu <leilk.liu-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>]

From: Leilk Liu <leilk.liu-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

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.

Leilk Liu (3):
  spi: mediatek: remove clk_disable_unprepare()
  spi: mediatek: fix spi clock usage error
  spi: Mediatek: Document devicetree bindings update for spi bus
