From ca0412a05756cd0b94751ca4d54fe6522f00b1f4 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 22 Nov 2018 18:23:19 +0800 Subject: [PATCH] ASoC: sunxi: sun50i-codec-analog: Add support for cpvdd regulator supply On the Allwinner A64 SoCs, the audio codec has a built-in headphone amplifier. This amplifier has a power supply separate from the rest of the analog audio circuitry, labeled cpvdd. This patch adds a DAPM widget for this supply, and ties it to the headphone amp widget.
