[PATCH v3 0/5] General RK3368 HDMI support and 2 outputs for RK3368-Lion

[Heiko Stuebner]

This series adds the necessary bits for HDMI output on RK3368 and enables
this on RK3368-Lion. At the same time, use the recently added DSI support
to enable the generic Video-Demo-adapter as an overlay on Lion as well.


The reason I'm shaving this Yak is that the recently added DSI support
created DTC warnings about a single endpoint with an address.

So it was either removing the @0 from the endpoint, or adding a second
output option :-) .


changes in v3:
- drop patches that already are applied
- added Quentin's Rb tags (except the one on hdmi enablement)
- moved hdmi supplies to lion.dtsi
- move bl-pwm enablement into a separate patch (and to haikou)

changes in v2:
- pick up Conor's Ack for the compatible
- fix the spelling errors reported by Diederik

[PATCH v3 1/5] arm64: dts: rockchip: Use phandle for i2c_lvds_blc on rk3368-lion haikou

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

i2c@0 on i2cmux2 does already have a phandle i2c_lvds_blc defined.

Use this one instead of replicating the hierarchy again, as this might
result in strange errors if the lion dtsi is changed at some point
in the future.

[PATCH v3 4/5] arm64: dts: rockchip: Enable pwm1 on rk3368-lion-haikou

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The pwm1 is exposed as BLT_CTRL signal on the MISC I/O pin header of the
haikou baseboard and the Qseven  standard specifies this signal is only
for PWM (either for a panel backlight or generic PWM).

So enable it in the Haikou baseboard for Lion.

I guess NPLL is an independent PLL available for VOP,

not really sure what you mean here.

The VOP-binding specifies the aclk, dclk and hclk clocks.

The NPLL is a possible source for quite a lot of peripherals on the rk3368
aclk_cci_pre,  sclk_tcp, vepu/vdpu, hevc, isp, gpu, gmac

So it's definitly not dedicated to the VOP, and thus should not
change frequency for the VOP alone, because that could affect
other blocks.
