2020-12-28soc/mediatek/mt8192: add rtc MT6359P driverYuchen Huang
Add rtc MT6359P driver for rtc init and rtc eosc calibration. Refactor mt8173 and mt8183 code by extracting common API. Move rtc_read and rtc_write to each SoC folder, because mt8173 and mt8183 access rtc via pmic wrapper, while mt8192 accesses it via pmif. Reference datasheet: Document No: RH-D-2018-0101.

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2019-11-26soc/mediatek/mt8183: disable BBLPM of DCXO coreWeiyi Lu
When we only enable XO_SOC and mask most BBLPM requests, the BBLPM HW arbiter will have DCXO core to enter Baseband Low-Power Mode(BBLPM). Under BBLPM mode, inaccurate(about 1.5KHz offset) 26MHz clocks from crystal is provided and crystal voltage will drop from 1.8V to 0.7V or lower. In order to ensure the stability by always outputting an accuarate system clock when system is running. We should disable BBLPM when only XO_SOC enabled.

Consider the association between modem[1] and DCXO, this patch is a fix for eb5e47d("mediatek/mt8183: update dcxo output buffer setting") [2] We should not disable XO_CEL and block the bblpm request when modem is still ON. For power-saving, we still could disable unused XO_CEL and mask request to disable unused power mode when modem is no longer be used.
