X-Git-Tag: v2013.04-rc3~1^2~76^2~2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=e2338704c0ac63c73d295f941ac0cfd8e05bd076;p=u-boot

Exynos: pwm: Use generic api to get pwm clk freq

Use generic api to get the pwm clock frequency

Test with command "sf probe 1:0; time sf read 40008000 0 1000".
Try with different numbers of bytes and see that sane values are obtained
Build and boot U-boot with this patch, backlight works properly.
