[PATCH v4 1/3] dt-bindings: clock: fix C3 PLL input parameter

[Xianwei Zhao via B4 Relay]

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

Add C3 PLL controller input clock parameters "fix".

The clock named "fix" was initially implemented in PLL clock controller
driver. However, some registers required secure zone access, so we moved
it to the secure zone (BL31) and accessed it through SCMI. Since the PLL
clock driver needs to use this clock, the "fix" clock is used as an input
source. We updated the driver but forgot to modify the binding accordingly,
so we are adding it here.

It is an ABI break but on a new and immature platform. Noboby could really
use that platform at this stage, so nothing is going to break on anyone
really.

So you mind if I take this one via my arm64-dt tree ?

There is no conflicting change in my tree so it's fine, yes.

[PATCH v4 2/3] arm64: dts: amlogic: add some device nodes for C3

[Xianwei Zhao via B4 Relay]

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

Add some device nodes for SoC C3, including periphs clock controller
node, PLL clock controller node, SPICC node, regulator node, NAND
controller node, sdcard node, Ethernet MAC and PHY node.

The sdacrd depends on regulator and pinctrl(select), so some
property fields are placed at the board level. The nand chip
is placed on the board, So some property fields about SPIFC
and NAND controller node are placed at the board level.
THe Ethernet MAC support outchip PHY, so place this property
field(select PHY) at the board level.

[PATCH v4 3/3] arm64: dts: amlogic: add C3 AW419 board

[Xianwei Zhao via B4 Relay]

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

Add Amlogic C3 C308L AW419 board. The corresponding binding
has been applied, therefore, this series does not need to
add a binding corresponding to the AW419 board.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.12/arm64-dt)

[1/3] dt-bindings: clock: fix C3 PLL input parameter
      https://git.kernel.org/amlogic/c/4ccba8cb2c5ca573d9bbf366e7d9d5e9761518c0
[2/3] arm64: dts: amlogic: add some device nodes for C3
      https://git.kernel.org/amlogic/c/520b792e83171efc8ec0b004412b44dabc044de0
[3/3] arm64: dts: amlogic: add C3 AW419 board
      https://git.kernel.org/amlogic/c/d4bd8f3023b68f72431e05ec6cbc793519b449cf

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

The v6.12/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.
