If you have any objections, please let us know. =============== [ Upstream commit 14ba3ec1de043260cecd9e828ea2e3a0ad302893 ] According to the datasheet: R10 (0Ah) VMID Impedance Control BIT 3:2 VMIDSEL DEFAULT 00 DESCRIPTION: VMID impedance selection control 00: 75kΩ output 01: 300kΩ output 10: 2.5kΩ output WM8737_VMIDSEL_MASK is 0xC (VMIDSEL - [3:2]), so it needs to left shift WM8737_VMIDSEL_SHIFT bits for setting these bits.
