Subject: [PATCH] arm64: dts: rockchip: drop pclk_xpcs from gmac0 on rk3568
|
|
|
|
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.
|
