[PATCH 0/2] RK3576 SATA Enablement

[Nicolas Frattaroli]

This is a tiny series to enable SATA on RK3576. It consists of a patch
to add the compatible to the bindings, and a second patch to add the
nodes to the SoC .dtsi.

I've only been able to test sata0 on my board (Sige5), but the
successful test gave me confidence that downstream's "dma-coherent"
property here is appropriate and true.

[PATCH 1/2] dt-bindings: ata: rockchip-dwc-ahci: add RK3576 compatible

[Nicolas Frattaroli]

The Rockchip RK3576 has two SATA controllers. They work the same as the
RK3568 SATA controllers, having the same number of clocks and ports.

[PATCH 2/2] arm64: dts: rockchip: add SATA nodes to RK3576

[Nicolas Frattaroli]

The Rockchip RK3576 features two SATA nodes. The first, sata0, is behind
combphy0, which muxes between pcie0 and sata0.

The second, sata1, is behind combphy1, which muxes between pcie1, sata1
and usb_drd1_dwc3.

I've only been able to test sata0 on my board, but it appears to work
just fine.
