SubjectRe: [PATCH 1/3] clk: exynos5433: Extend list of available AUD_PLL output frequencies
Hi Sylwester,

When I developed the clk-exynos5433.c I referred to the following description.
TRM specified that "Samsung recommends only the values
between 252MH ~ 400MHz in the PMS2460X PMS value" for aud_pll.

It looks like that you refer to clk-exynos5420.c driver.
But, I'm wondering exynos5433 might not guarantee the additional clock
of this patch as the stable clock.
