Initial device tree support for Qualcomm SDM630 SoC and
Sony Pioneer (Xperia XA2).
SDM630 is based off of the SDM660 soc and all SDM660 specific drivers are
compatible with it. SDM660 is also based off of MSM8998 so it uses some
of its drivers aswell.
The device tree is based on the CAF 4.4 kernel tree.
The device can be booted into the initrd with a shell over UART.

Consider adding both sdm630 and sdm660 compatibles to the bindings and
drivers and use the right one in the dts, in case we find details that
differs in the future.

Remove a few of these extra empty lines and add the rpm_requests channel
here while you're at it:
rpm_requests: glink-channel {
compatible = "qcom,rpm-sdm660";
qcom,glink-channels = "rpm_requests";
};

Please 0-pad addresses in "reg", makes it easier to sort them as well
(but keep the @address after the node name unpadded).

Please update the apcs ipc driver with a sdm660 compatible and update
this.

This includes pinctrl and GCC?

Are you meaning to put this in the pioneer DTS or just drive strength and bias?

Okay, should the same still apply once more stuff is in soc? Or should I use references for them?

I have started to rework that based on the last year's discussions, but
haven't posted any patches yet.

The drive-strength and bias are board-specific properties, so we want to
keep those in the board file, so I mean push the pinconf part into the
board dtsi.
