This commit: - makes the GOP_DP (bit 9) gatable clock a child clock of the SD_MMC_GOP (bit 18) clock, as it should have been. The clock for bit 18 was just named SD_MMC, but since it also covers the GOP block, it is renamed SD_MMC_GOP. - makes the MG (bit 5) gatable clock a child clock of the MG_CORE clock (bit 6) Signed-off-by: Thomas Petazzoni <redacted> --- drivers/clk/mvebu/cp110-system-controller.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-)
