add the clocks and clock-names in DT property, gpmi-io clock is mandatory for all platforms, but some platforms, such as i.MX6Q may need more extra clocks for submodules. More details please refer to the SoC reference manual. Signed-off-by: Han Xu <han.xu@nxp.com> --- Documentation/devicetree/bindings/mtd/gpmi-nand.txt | 9 +++++++++ 1 file changed, 9 insertions(+)
