Subject: [PATCH 0/3] ARM: dts: use the SDHC MMC controller for eMMC
Date: Sat, 20 Jun 2020 18:36:51 +0200 [thread overview]
Message-ID: <20200620163654.37207-1-martin.blumenstingl@googlemail.com> (raw)
Amlogic Meson6/8/8b/8m2 SoCs have two built-in MMC controllers:
- SDIO (which is supported on mainline for a long time now but is
limited to ~40MHz bus frequency)
- SDHC (which supports up to HS-200 modes at ~100MHz bus frequency but
for which we didn't have a driver)
Boards with NAND flash will now be able to use the SDIO controller for
SDIO based wifi cards and the SDHC controller for the SD card slot.
Boards with eMMC, SD card and SDIO wifi can only use two out of three
MMC based devices for now until the MMC core and Meson SDIO driver gain
support for multiple "mmc-slots" per controller.
Now that we have a driver for it, add the SDHC controller to meson.dtsi
and wire up the eMMC connection on the Endless Mini EC-100 and the
Odroid-C1.
