[PATCH] arm64: dts: rockchip: use cs-gpios for spi1 on ringneck

[Jakob Unterwurzacher]

From: Jakob Unterwurzacher <jakob.unterwurzacher@cherry.de>

Hardware CS has a very slow rise time of about 6us,
causing transmission errors when CS does not reach
high between transaction.

It looks like it's not driven actively when transitioning
from low to high but switched to input, so only the CPU
pull-up pulls it high, slowly. Transitions from high to low
are fast. On the oscilloscope, CS looks like an irregular sawtooth
pattern like this:
                         _____
              ^         /     |
      ^      /|        /      |
     /|     / |       /       |
    / |    /  |      /        |
___/  |___/   |_____/         |___

With cs-gpios we have a CS rise time of about 20ns, as it should be,
and CS looks rectangular.

This fixes the data errors when running a flashcp loop against a
m25p40 spi flash.

With the Rockchip 6.1 kernel we see the same slow rise time, but
for some reason CS is always high for long enough to reach a solid
high.

The RK3399 and RK3588 SoCs use the same SPI driver, so we also
checked our "Puma" (RK3399) and "Tiger" (RK3588) boards.
They do not have this problem. Hardware CS rise time is good.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250619 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

naming the node -gpio trigger the bot, I guess a better name would
be something with -pin at the end instead.

please also provide a

It feels more futur proof when overriding the pinctrl-0 entry
to also state we only expect that one.
