[PATCH 1/9] ARM: dts: rockchip: rk3288-vyasa: Remove vdd_log from rk808, DCDC_REG1

[Jagan Teki]

vdd_log, never used on DCDC_REG1 of rk808 from latest schematic so
remove the same and update the regulator-name as 'vdd_arm' to sync
with existing rk3288 board dts files.

not sure I understand this one.

I.e. the regulator should be at 3.3V anyway and only when it
reaches UHS speeds should the mmc core reduce the voltage
to 1.8V, so having this variable here, shouldn't pose a problem?

So maybe you could explain a bit more what the problem is?


Thanks
Heiko

[PATCH 3/9] ARM: dts: rockchip: rk3288-vyasa: Use vmmc-supply from PMIC

[Jagan Teki]

rk808, SWITCH_REG1 has configured for sdmmc regulator as vcc_sd,
so use the same by renaming vcc33_sd to vcc_sd(as per schematic)
and drop explicit regulator definition from root.

applied for 4.15, after dropping the RK_GPIO8 addition and making
the pin use "8" directly instead of the outdated constant.

It isn't planned to extend this GPIOx -> x ... instead it is more or
less deprecated.

[PATCH 9/9] ARM: multi_v7_defconfig: Statically build RTC_DRV_RK808

[Jagan Teki]

RTC_DRV_RK808 need to have build statically for the platforms
do use MFB_RK808 so replace module with statical link.

why would you need this to be compiled on? MFD_RK808 will happily
just create the platform-devices which are then bound to the RTC
driver later once the module is ready.

Yeah, that can be true but seems like rk808 need rtc at the
beginning(like boot time) because we observed the boot hang even with
gmac (like one with HDMI [1]) eventually booting continue only when it
linked statically.
