[PATCH] arm64: dts: sdm630 SoC and Sony Pioneer (Xperia XA2) support

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.

Initial device tree support for Qualcomm SDM630 SoC and

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.

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.

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.

Please put these in the sdm630.dtsi directly, rather than spreading the

Please reference this by &blsp1_uart1, rather than duplicating the

We expect the board to always override this, so no need to specify it

Initial device tree support for Qualcomm SDM630 SoC and

SDM630 is based off of the SDM660 soc and all SDM660 specific drivers

some

of its drivers aswell.

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.

This includes pinctrl and GCC?

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.

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
