arm64: dts: rockchip: add ROCK Pi S DTS support
ROCK Pi S is RK3308 based SBC from radxa.com. ROCK Pi S has a, - 256MB/512MB DDR3 RAM - SD, NAND flash (optional on board 1/2/4/8Gb) - 100MB ethernet, PoE (optional) - Onboard 802.11 b/g/n wifi + Bluetooth 4.0 Module - USB2.0 Type-A HOST x1 - USB3.0 Type-C OTG x1 - 26-pin expansion header - USB Type-C DC 5V Power Supply This patch enables - Console - NAND Flash - SD Card Signed-off-by: Akash Gajjar <akash@openedev.com> [sjoerd: Sort dt nodes, drop properties duplicated from dtsi] Signed-off-by: Sjoerd Simons <sjoerd@collabora.com> Link: https://lore.kernel.org/r/20220614064858.1445817-3-sjoerd@collabora.com Signed-off-by: Heiko Stuebner <heiko@sntech.de>
