[PATCH v2 0/3] add some node for amlogic c3

[Xianwei Zhao via B4 Relay]

Add some node for board AW409 and support board C308l AW419.

Signed-off-by: Xianwei Zhao <xianwei.zhao@amlogic.com>
---
Changes in v2:
- Delete unused sdio node in board level dts.
- Add the description of modifying the binding in commit msg.
- Add the reason why some node property fileds place at board level in commit msg.
- Link to v1: https://lore.kernel.org/r/20240806-c3_add_node-v1-0-c0de41341632@amlogic.com

[PATCH v2 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.

Fixes: 0e6be855a96d ("dt-bindings: clock: add Amlogic C3 PLL clock controller")

[PATCH v2 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 v2 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.
