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.
Signed-off-by: Padmavathi Venna padma.v@samsung.com Signed-off-by: Akshay Saraswat akshay.s@samsung.com Acked-by: Simon Glass sjg@chromium.org --- Changes since v2: - Replaced "exynos5_get_pwm_clk" with "clock_get_periph_rate" in get_pwm_clk instead of replacing everywhere. - Added "Acked-by: Simon Glass".
Changes since v1: - Restored get_pwm_clk call in case of non-exynos5 cpu.
