This is a small collection of improvements for the Odroid-C1 board.
My main goal is to prepare the CPU voltage regulator as I'm using
the Odroid-C1 to test my changes which will enable CPU frequency
scaling on Meson8/Meson8b/Meson8m2.

While I was going through the schematics anyways I added more
regulators, enabled the SAR ADC and added the /chosen/stdout-path
property to make debugging with "earlycon" easier.

schematics for the board are published by Hardkernel and can be found
here: [0]

NOTE: This series depends on my patch "ARM: dts: meson8b: add the
I2C_A, PWM_C and UART_B pins" [1] from my other series called
"Meson8b: add support for the Endless Mini EC-100" as this defines
the "pwm_c1_pins" for the CPU voltage regulator (which is controlled
via PWM).

Applied to v4.20/dt (on top of the Endless series)

Thanks for pointing out the dependencies,
