[Xianwei Zhao via B4 Relay]

Amlogic S6 S7 and S7D are application processors designed for
hybrid OTT/IP Set Top Box and high-end media box applications.

Add the new S6 SoC/board device tree bindings.
Add the new S7 SoC/board device tree bindings.
Add the new S7D SoC/board device tree bindings.

Add basic support for the S6 based Amlogic BL209 board, which describes
the following components: CPU, GIC, IRQ, Timer and UART. These are capable of
booting up into the serial console.

Add basic support for the S7 based Amlogic BP201 board, which describes
the following components: CPU, GIC, IRQ, Timer and UART. These are capable of
booting up into the serial console.

Add basic support for the S7D based Amlogic BM202 board, which describes

[PATCH 4/7] dt-bindings: serial: amlogic,meson-uart: Add compatible string for S6/S7/S7D

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Amlogic S6/S7/7D SoCs uses the same UART controller as S4 SoCs and G12A.
There is no need for an extra compatible line in the driver, but
add S6/S7/S7D compatible line for documentation.

[PATCH 7/7] arm64: dts: add support for S7D based Amlogic BM202

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Amlogic S7D is an advanced application processor designed for
hybrid OTT/IP Set Top Box and high-end media box applications.

Add basic support for the S7D based Amlogic BM202 board, Reusing
S7 basic components: CPU, GIC, IRQ, Timer and UART.
These are capable of booting up into the serial console.

I'll apply them this week except patch 4,

so can you send patch 4 separately since it goes via the tty tree ?

I will send patch 4 separately.
The following patches(5 6 7) can be not included for now. Without the 
patch 4, the command "make ARCH=arm64 dtbs_check W=1" will fail to execute.

I have already sent patch 4 separately. From Rob's reply, do you think 
it can be picked up together?

These changes has been applied on the intermediate git tree [1].

The v6.16/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
