From f09872c5bd0fa2d4b6f4e52259ab3355e8489244 Mon Sep 17 00:00:00 2001 From: Bo-Chen Chen Date: Thu, 29 Sep 2022 18:45:37 +0800 Subject: soc/mediatek/mt8188: Update mtcmos settings for display and audio - For display, only vdosys0_pwr_con and edp_tx_pwr_con settings are required. - For audio, it requires powering on adsp_ao_pwr_con, adsp_infra_pwr_con and audio_pwr_con. - Add new power domain data `ext_buck_iso_bits` for buck isolation control. BUG=b:244208960 TEST=access display registers successfully.
