From 73106f75bf9498ff5d50f1052ad3cf03730d806d Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 20 Jun 2020 18:36:52 +0200 Subject: [PATCH] ARM: dts: meson: add the SDHC MMC controller Meson6, Meson8, Meson8b and Meson8m2 are using a similar SDHC controller IP which typically connects to an eMMC chip (because unlike the SDIO controller the SDHC controller has an 8-bit bus interface). On Meson8, Meson8b and Meson8m2 the clock inputs are all the same. However, Meson8m2 seems to have an improved version of the SHDC controller IP which doesn't require the driver to wait manually for a flush of a DMA transfer. Thus every SoC has it's own compatible string so if more difference are discovered they can be implemented.
