Subject: [PATCH] ARM: dts: tegra20-glide: Fix audio power binding
|
||
|
|
|
||
|
|
The LDO definition in wm8994 node is used for internal LDOs, but not for
|
||
|
|
powering the chip, so we use the fixed regulator to resolve this.
|
||
|
|
All regulators of wm8994 are defined to suppress messages in dmesg.
|
||
|
