Subject: [PATCH v2 13/13] arm64: dts: qcom: lemans-evk: Add sound card
From: Mohammad Rafi Shaik <mohammad.rafi.shaik@....qualcomm.com>
Add the sound card for Lemans-Evk board and verified playback
functionality using the max98357a I2S speaker amplifier and I2S
microphones. The max98357a speaker amplifier is connected via
High-Speed MI2S HS0 interface, while the microphones utilize the
HS2 interface. This patch also introduces pin control support
for the High-Speed I2S interfaces.
