If anyone has any objections, please let me know. ------------------ From: HyeongJun An [ Upstream commit d0567ca9a2faa33efbe5ae84ef7b86423a93bffd ] The DAC and ADC 128x Oversampling Switches use bit 5 of R10 and R14. Table 66 of the WM8978 datasheet puts DACOSR128 and ADCOSR128 at bit 3 of those registers. In R14, bit 5 is inside HPFCUT[6:4], which the High Pass Cut Off control owns. So turning on ADC oversampling changes the high pass cut-off, and the oversampling bit cannot be set. In R10, bit 5 is reserved, so the DAC switch has no effect. Use bit 3 for both.
