[PATCH 0/6] Enable clock controllers on MSM

[Stephen Boyd]

This patchset enables the clock controller hardware on some DT based
MSM devices. It also hooks up the 8974 SoC's serial device to the
clock controller so that we can get a serial console.

This patchset is based on Rohit's 8974 patches[1] and my follow up
dts update patches[2]. For it to be fully functional you'll also need
to apply the MSM clock driver patches[3] or wait for them to land in
linux-next.
