Subject: ASoC: wm8510 pll settings
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=86027ae78c9294bb450b76eec28cfb431a8fb3ee;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ASoC: wm8510 pll settings

When setting WM8510_MCLKDIV the pll was turned off.

When setting pll frequency you got twice the expected freq, because
the  code calculated  with postscaler of 8,  but  the hardware divide by 4.
