The compatible property is required for some vendor-specific device trees, such as Amlogic's meson-mx-sdio, but is unnecessary for others, like Microchip's DTS. To resolve unintended warnings for configurations that do not require it, remove compatible from the required properties in mmc-slot.yaml. Since meson-mx-sdio still requires compatible, explicitly add it to its required list in amlogic,meson-mx-sdio.yaml.

title: Amlogic Meson6, Meson8 and Meson8b SDIO/MMC controller
|
|
|
|
description: |
|
|
The highspeed MMC host controller on Amlogic SoCs provides an interface
|
|
for MMC, SD, SDIO and SDHC types of memory cards.
|
|
|
|
Supported maximum speeds are the ones of the eMMC standard 4.41 as well
|
|
as the speed of SD standard 2.0.
|
|
|
|
The hardware provides an internal "mux" which allows up to three slots
|
|
to be controlled. Only one slot can be accessed at a time.
