[RESEND PATCH 0/3] Clock fixes for Ingenic SoCs

[Aidan MacDonald]

Resending this series since it appears none of the patches were picked up
the first time around.

I ran across a problem trying to get Linux running on an Ingenic X1000 SoC:
since the memory clock isn't referenced by any driver, it appears unused and
gets disabled automatically. After that, the system hangs on any RAM access.

There is a hack in board-ingenic.c to forcibly enable the CPU clock, but this
is insufficient for the X1000 since the memory clock has its own gate and mux
that isn't tied to the CPU.

This patch series fixes the bug by adding CLK_IS_CRITICAL flags to important
clocks, which seems to be the approach used in many other SoC clock drivers.

Aidan MacDonald (3):
  clk: ingenic: Allow specifying common clock flags
  clk: ingenic: Mark critical clocks in Ingenic SoCs
  mips: ingenic: Do not manually reference the CPU clock
