2021-03-15	mb/google/asurada: revise PMIC and RTC initialization	Yidi Lin
	Move the initialization from bootblock to romstage for following reasons: - Follow MT8183 initialization sequence. - PMIC and RTC functions are only called after verstage. - Reduce bootblock size. - PMIC initialization setting is complex and may need to be changed by an RW firmware update.

2021-03-10	soc/mediatek/mt8192: mt6315: update initial flow	Hsin-Hsiung Wang
	We saw EXT_PMIC_EN1 and PPVAR_DVDD_PROC_BC power off sequence failure, and after checking MT6315 MT6315 PMIC protection key summary.xlsx and MT6315 Top and CLK programming guide.docx, we found there are something wrong about the sequence of magic key protection flow and clk setting. Update correct initial flow.

2021-03-10	soc/mediatek/mt8192: mt6315: update correct slave id	Hsin-Hsiung Wang
	The initial settings for MT6315 were not applied correctly because the setup process didn't specify correct slave id (incorrectly always sending 0), and may cause failure in power off sequence.
