From: Stefan Riedmueller s.riedmueller@phytec.de
There is no need to explicitly set the default gpmi clock rate during boot for the i.MX 6 since this is done during nand_detect anyway.
Signed-off-by: Stefan Riedmueller s.riedmueller@phytec.de Cc: stable@vger.kernel.org --- @stable: This patch fixes a bug because this (superfluous) call to clk_set_rate() misses the required clock gating. The resulting clock glitches can prevent the system from booting.
