From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> DEVICE_CFG2 can select ratio from user defined ratio and LOCKCLK is for it. But current driver sets fixed 0 value. This patch fixes it. Note is that current cs2000 driver is using/supporting only ratio0 (= ch0) now. DEVICE_CFG2 can select STATIC/DYNAMIC ratio mode, and current cs2000 driver is selecting STATIC mode, but it was not understandable on current code. This patch also solve this issue.
