[PATCH 07/18] ARM: imx: clk-vf610: leave DDR clock on

Show all headers | View raw

To use STOP mode without putting DDR3 into self-refresh mode, we
need to keep the DDR clock enabled. Use the new gate configuration
with a value of 2 to make sure that the clock is enabled in RUN,
WAIT and STOP mode.
