This series adds K3 PDMA request numbers, documents the K3 SPI
compatible, and enables SPI0 on the K3 CoM260-IFX.

This series is available here:
  https://github.com/imguoguo/linux/tree/k3-com260-spi-v1

This series is based on v7.2-rc2.

Add a local DTS header that gives symbolic names to the SpacemiT K3
PDMA request lines of the non-secure peripherals. Device trees can use
these K3_PDMA_* macros instead of hard-coded request numbers when wiring
a peripheral "dmas" property.

The K3 SPI controller is compatible with K1, so allow K3 device trees to
use "spacemit,k1-spi" as fallback.

SPI0 is the first enabled PDMA consumer on CoM260-IFX, so enable the
PDMA controller together with SPI0.

The board exposes SPI0 on its 40-pin header:

  pin 19: MOSI
  pin 21: MISO
  pin 23: SCLK
  pin 24: CS0

Define the pinctrl state used by this header wiring, and describe the SPI
NOR on chip select 0 for the current validation setup.

(This was tested using a Winbond W25Q64JV SPI NOR chip.)

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The commit message claims to describe a SPI NOR flash chip on chip select 0, but the corresponding device tree node is absent.
- [Medium] The pinctrl configuration sets the SPI pad voltage to 1.8V, which conflicts with the 3.3V Winbond W25Q64JV SPI NOR flash mentioned in the commit message.

commit 195bf5fbf14f1dbf36d3f0697603287770b0c9db
Author: Zhengyu He <hezhy472013@gmail.com>

riscv: dts: spacemit: enable SPI0 on K3 CoM260-IFX

This commit enables the PDMA controller and SPI0 on the K3 CoM260-IFX board.
It also adds the pinctrl states for the SPI0 pins exposed on the board's 40-pin
header.

[Severity: Medium]
The commit message states this patch will "describe the SPI NOR on chip select
0 for the current validation setup", but is the child node for the flash chip
missing here?

[Severity: Medium]
Does this 1.8V power source configuration match the validation setup described
in the commit message?

The commit message mentions testing with a Winbond W25Q64JV, which is a 3.3V
component (the 1.8V equivalent is the W25Q64JW). If the SoC IO is driving
1.8V signals without a level shifter, it might fail to meet the 3.3V chip's
input high voltage thresholds. Could this be a typo in the commit message, or
is the power-source value incorrect for this board?
