[PATCH 1/2] ARM: dts: rockchip: rk3036: Move PHY reset to ethernet-phy node

[PATCH 1/2] ARM: dts: rockchip: rk3036: Move PHY reset to ethernet-phy node

[Fabio Estevam]

According to rockchip,emac.yaml, 'phy-reset-duration' and 'phy-reset-gpios'
are not valid properties.

Use the valid 'reset-gpios' and 'reset-assert-us' properties under
the etherne-phy node.

This fixes the following dt-schema warning:

Unevaluated properties are not allowed ('phy-reset-duration',
'phy-reset-gpios' were unexpected)

[PATCH 2/2] ARM: dts: rockchip: rk3288: Remove rockchip,grf from tsadc

[Fabio Estevam]

According to rockchip-thermal.yaml, RK3288 does not require rockchip,grf,
so remove this invalid property.

This fixes the following dt-schema warning:

tsadc@ff280000 (rockchip,rk3288-tsadc): False schema does not allow [[53]]

The rockchip_thermal driver also confirms that grf is not needed as
the rk3288_tsadc_data contains:
 .grf_required = false,

please don't send patches that "simply" fix devicetree warnings.

As you can see in [0] the driver uses these properties currently.
So while this fixes schema warnings, it will break the actual boards.

So first of all you'll need to adapt the driver to handle the "official"
properties and also provide a fallback in the driver for old devicetrees.

Only then can we think about modifying the actual devicetrees for
the future.


Thanks
Heiko

The rk3066a-rayeager board describes the reset-gpios inside the
Ethernet PHY node:

https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/rockchip/rk3066a-rayeager.dts#L155-L157

Is this broken?

No it isn't :-) .

That's what I get when I try looking at patches on a saturday before
coffee ;-) .

With the reset moving into the phy-node, the phy driver will trigger its
reset itself of course. The arc-mdio also request the reset-gpio as
optional, so the whole thing won't fail if te gpio is not present.

Sorry about the noise, the patch is correct obviously.

Does this need a "Fixes:" tag (haven't checked)? And could stable benefit
from this?
