Subject: [PATCH 0/2] Use "dma-noncoherent" to handle Rockchip RK358x 3588001 errata

This is a small series that makes the "dma-noncoherent" DT property used
for handling the 3588001 errata for Rockchip RK3588, RK3588S and RK3582
SoCs, which is the preferred way over checking the compatibles. [1]

Older versions of the Rockchip RK3588 and RK3588S SoC dts(i) files failed
to specify the "dma-noncoherent" DT property, so checking the compatibles
remains required for backward SoC dts(i) compatibility.
