Subject: [PATCH v3 0/2] Add lpass pin control support for audio on sc7280 based targets

This patch set is to add lpass pin control support for Audio over I2S,
wcd codec and digital mics.
This patch set depends on:
-- https://patchwork.kernel.org/project/alsa-devel/patch/[email protected]/

Changes Since V2:
-- Move lpass pin control node to main dtsi file.
-- Sort nodes alphabetically.
-- Remove redundant wcd reset gpio nodes.
-- Remove redundant input-enable field in dmic pin control nodes.
-- Update amp_en node.
-- Fix typo errors.
-- Modify node names.
Changes Since V1:
-- Merge pinmux and pinconf properties in amp_en and wcd pin reset node.
-- Split common i2s pin control nodes to functionality specific nodes.
-- Move board specific properties to board specific dtsi file.
-- Update dmic pin control node name.
