Subject: ASoC: wm8961 - clear WM8961_MCLKDIV bit for freq <= 16500000
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2f7dceeda4708f470fd927adb3861bd8ebbe2310;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git
ASoC: wm8961 - clear WM8961_MCLKDIV bit for freq <= 16500000
MCLKDIV bit of Register 04h Clocking1:
0 : Divide by 1
1 : Divide by 2
Thus in the case of freq <= 16500000, we should clear MCLKDIV bit.
