From 3a605ac1b42ff7cc0bb9d0735088c34260395015 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sun, 10 May 2015 11:35:06 +0800 Subject: ASoC: wm8737: Fixup setting VMID Impedance control register MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 14ba3ec1de043260cecd9e828ea2e3a0ad302893 upstream. 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.
