Subject: ARM: tegra: colibri_t30: add missing regulators
X-Git-Tag: v5.4-rc1~2318^2~31^2~88
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a03fb6312280b19234e728689ab6a2f66a7a2cf1;p=platform%2Fkernel%2Flinux-rpi.git

ARM: tegra: colibri_t30: add missing regulators

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