[PATCH 0/2] the supporting for eDP panel of Firefly

[Randy Li]

After the IRQ deadlock issue is solved, I can finally offer the supporting
of the eDP panel sold by the T-CHIP Firefly.

I don't think it is necessary to enable two vop for a eDP panel, even
the vop lite is enough for the resolution of this panel.

I have verified those patch with the kmssink from Gstreamer.
but I still got a few warnings message, those message comes from booting time.

You may need the following patch to make PWM backlight work, or merge it
into the bootloader.

[PATCH 1/2] ARM: dts: rockchip: add eDP panel support for Firefly

[Randy Li]

This patch adds the supporting to the eDP panel sold by
the T-CHIP for the Firefly RK3288.

The InvenSense MPU6050 sensor at the botton of the panel
is also enabled.

The Firefly RK3288 Reload use a different GPIO pin to enable
the power of the eDP panel.
