[PATCH 1/2] arm64: dts: rockchip: move rk3399-sapphire sdio to excavator baseboard

[Heiko Stuebner]

The sdio signals are routed through the connector to the baseboard,
where the wifi module is also located. So move the sdio node to
the excavator as well.

Hi Vicente,

after looking at the issue, I guess something like this and the following
patch should help your situation?
I've heared about the sapphire being used standalone some times and
thus think it can be justified to add that standalone version.

[PATCH 2/2] arm64: dts: rockchip: add a standalone version of the rk3399 sapphire

[Heiko Stuebner]

While the sapphire board is a system-on-module and mostly used with the
excavator baseboard, it is also possible to use it standalone without
any base. So add a board-variant for this type.

[PATCH 1/2] arm64: dts: rockchip: move rk3399-sapphire i2s2 to daughterboard

[Vicente Bergas]

The i2s2 drives the HDMI audio, which has the connector on the daughterboard.

Hi Heiko,

I have tested your patches on stable Linux 4.15.4 and worked fine.
There are only two missing bits: the power-button and the HDMI audio.
With this two extra patches, I have been able to test the power button
and it worked fine.
The HDMI audio was not working before nor after, but, the TRM says that
i2s2 is the audio source for the HDMI port.

Regards, Vicente.

Ah, could you remove these assigned-clock* as well?
reference clock is needed for pcie_phy, not pcie controller.
Actually pcie_phy doesn't need this since rk3399 clock driver
already take care of this.

Otherwise,

I've applied both patches into a temporary branch for likely 4.18 now
with the tags from Shawn.

Reason is that we also have a fix for 4.16 in a different branch fixing
the ep-gpios property on sapphire and having these things conflict
will end up in a lot of chaos, as that fix is not yet in the mainline kernel
but only in an intermediate state.

So likely the pcie move will have to wait for 4.18 to make it easier
on everybody.
