From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

This adds basic support for the Qualcomm sa8775p platform and its reference
board: sa8775p-ride. The dtsi contains basic SoC description required for
a simple boot-to-shell. The dts enables boot-to-shell with UART on the
sa8775p-ride board. There are three new drivers required to boot the board:
pinctrl, interconnect and GCC clock. Other patches contain various tweaks
to existing code. More support is coming up.

This is faaaaar more than what your DT node specifies.

With these two fixed, LGTM:

One more thing, this should be qcom,sa8775p-gcc.

This patch didn't make it to the list. Please check if you can fix or 
split it somehow?

It's a known issue with lists clipping messages that are too long.
I'll forward it to you.

As the driver didn't get to the list, I'll comment OOB.

Please use clk_regmap_phy_mux_ops where applicable (PCIe PIPE clocks).

have two parents.
