2019-09-04mediatek/mt8183: postpone dcxo low power mode settingWeiyi Lu
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.

2019-07-07mediatek/mt8183: update dcxo output buffer settingWeiyi Lu
DCXO consists of core that generates clock and output buffers that provide clock to other peripheral components. This patch mainly eliminates the extra power consumption of output buffers. We only enable the buffer for SOC and disable unused buffers for power-saving. Also disable useless buffer power mode to guarantee the lowest power state. BRANCH=none TEST=Boots correctly on Kukui.

When system shuts down, RTC enable eosc calibration feature to save power. Then coreboot RTC driver needs to call rtc_enable_dcxo function at every boot to switch RTC clock source to dcxo.

1. Fix RTC lpd settings. Rewrite powerkeys after lpd init to enable low power detect function. 2. Rearrange RTC initialization flow. 3. Add return status for rtc_init. 4. Add log if calling pwrap_write or pwrap_read fail. 5. Increase timeout time to resolve unexpected timeout.
