Subject: [PATCH v2] arm64: dts: rk3568: drop pclk_xpcs from gmac0

From: Frank Wunderlich <[email protected]>

pclk_xpcs is not supported by mainline driver and breaks dtbs_check

following warnings occour, and many more

rk3568-evb1-v10.dt.yaml: ethernet@fe2a0000: clocks:
[[15, 386], [15, 389], [15, 389], [15, 184], [15, 180], [15, 181],
[15, 389], [15, 185], [15, 172]] is too long
From schema: Documentation/devicetree/bindings/net/snps,dwmac.yaml
rk3568-evb1-v10.dt.yaml: ethernet@fe2a0000: clock-names:
['stmmaceth', 'mac_clk_rx', 'mac_clk_tx', 'clk_mac_refout', 'aclk_mac',
'pclk_mac', 'clk_mac_speed', 'ptp_ref', 'pclk_xpcs'] is too long
From schema: Documentation/devicetree/bindings/net/snps,dwmac.yaml

after removing it, the clock and other warnings are gone.

pclk_xpcs on gmac is used to support QSGMII, but this requires a driver
supporting it.
Once xpcs support is introduced, the clock can be added to the
documentation and both controllers.

Applied as fix for 5.17, thanks!

[1/1] arm64: dts: rk3568: drop pclk_xpcs from gmac0
commit: 85a8bccfa945680dc561f06b65ea01341d2033fc

I've adapted the subject to
arm64: dts: rockchip: drop pclk_xpcs from gmac0 on rk3568
though. Please use prefixes matching the subsystem
(i.e. arm64: dts: rockchip: ... in this case)


Best regards,
