Subject: [PATCH] arm64: dts: allwinner: a64: pine64-plus: Add PHY regulator
delay
Depending on kernel and bootloader configuration, it's possible that
Realtek ethernet PHY isn't powered on properly. It needs some time
before it can be used.
Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.

Subject: [PATCH] clk: sunxi-ng: h6: Use sigma-delta modulation for audio PLL
Audio devices needs exact clock rates in order to correctly reproduce
the sound. Until now, only integer factors were used to configure H6
audio PLL which resulted in inexact rates. Fix that by adding support
for fractional factors using sigma-delta modulation look-up table. It
contains values for two most commonly used audio base frequencies.

Subject: [PATCH] arm64: dts: allwinner: a64: sopine-baseboard: Add PHY
regulator delay
It turns out that sopine-baseboard needs same fix as pine64-plus
for ethernet PHY. Here too Realtek ethernet PHY chip needs additional
power on delay to properly initialize. Datasheet mentions that chip
needs 30 ms to be properly powered on and that it needs some more time
to be initialized.
Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.
Note that issue was found out and fix tested on pine64-lts, but it's
basically the same as sopine-baseboard, only layout and connectors
differ.
