Subject: ASoC: wm8940: Fix setting PLL Output clock division ratio
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=49fa4d9b5aeafb985abe8cb8cdf6432690c49ad3;p=mv-sheeva.git

ASoC: wm8940: Fix setting PLL Output clock division ratio

According to the datasheet:
The PLL Output clock division ratio is controlled by BIT[5:4] of
WM8940_GPIO register(08h).
Current code read/write the WM8940_ADDCNTRL(07h) register which is wrong.
