2016-06-25nvmem: imx-ocotp: handling clockPeng Fan
Before access ocotp nvmem area, the clock should be enabled. Or, `hexdump nvmem` will hang the system. So, use such flow: " 1. clock_enable_prepare 2. read nvmem ocotp area 3. clock_disable_unprepare " Signed-off-by: Peng Fan <van.freenix@gmail.com> Cc: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Cc: Maxime Ripard <maxime.ripard@free-electrons.com> Cc: Shawn Guo <shawnguo@kernel.org> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
