[PATCH 1/3] ARM: dts: rockchip: Fix vcc10_lcd name and voltage for rk3288-vyasa

[Jagan Teki]

According to hardware schematics of Vyasa RK3288 the
actual name used for vcc10_lcd is vdd10_lcd.

regulator suspend voltage can rail upto 1.0V not 1.8V.

Fix the name and suspend voltage for vcc10_lcd regulator.

[PATCH 2/3] ARM: dts: rockchip: Fix ddc-i2c-bus for rk3288-vyasa

[Jagan Teki]

ddc-i2c-bus routed for HDMI is i2c2 not i2c5 on
Vyasa RK3288 board.

Add support for fixing the same.

[PATCH 3/3] ARM: dts: rockchip: Add vcc50_hdmi for rk3288-vyasa

[Jagan Teki]

Add vcc50_hdmi regulator for Vyasa RK3288 board.

VCC50_HDMI is the real name used for this regulator as
per the schematics.

This regulator used for HDMI connector by detecting the
cable via HDMI_EN gpio and input rails are sourced from
VSUS_5V regulator.
