This was found while preparing a workaround patch using equally named property for RockPro64 [1] which uses the same RK3399 SoC as Pinebook Pro. bus-scan-delay-ms might have been picked to Pinebook Pro DT from my earlier patches for RockPro64 custom kernels like [2] or [3].

I did not find any code reference to removed property and believe it has been accidentally copied over, but there could always be some surpise. Testing and comments how to proceed are welcome. arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts | 1 - 1 file changed, 1 deletion(-) base-commit: f6e1ea19649216156576aeafa784e3b4cee45549 diff --git a/arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts b/arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts index 06d48338c836..9589646824bf 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts +++ b/arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts @@ -788,7 +788,6 @@ &pcie_phy { }; &pcie0 { - bus-scan-delay-ms = <1000>; ep-gpios = <&gpio2 RK_PD4 GPIO_ACTIVE_HIGH>; max-link-speed = <2>; num-lanes = <4>;
