From 2d3bb400f37b86c3da3a64a9ee4c1d79caa2fdd6 Mon Sep 17 00:00:00 2001 From: Johan Jonker Date: Sat, 9 Apr 2022 18:55:09 +0200 Subject: [PATCH] rockchip: mmc: rockchip_dw_mmc: add rk3066/rk3188 support The Rockchip SoCs rk3066/rk3188 have MMC DT nodes with as compatible string "rockchip,rk2928-dw-mshc". Add OF_PLATDATA support to the existing driver with help of a DM_DRIVER_ALIAS. This type needs a permanent enabled fifo. The other Rockchip SoCs always have the property "u-boot,spl-fifo-mode" in the MMC DT nodes, because MMC to SRAM can't do DMA. Make this property a requirement for MMC OF_PLATDATA structures. The property "fifo-mode" must be added for all other compile modes.
