[PATCH v2 08/34] ARM: tegra: apalis_t30: add missing regulators

From: Marcel Ziswiler
Date: Fri Aug 31 2018 - 12:41:28 EST


From: Marcel Ziswiler <marcel.ziswiler@xxxxxxxxxxx>

Add missing regulators:
- reg_module_3v3_audio being VDDA supply of SGTL5000
- VDDD supply of SGTL5000 actually being reg_1v8_vio
- carrier board HDMI supply being reg_5v0
- carrier board reg_3v3 actually being backlight and panel power supply
