The existing RPi3 acpi entries for the Arasan
and sdhci controllers needs updating to work
with the RPi4. This is done by adding a caps
override for the legacy Arasan controller and
then adding an entirely new entry for the newer
eMMC2 controller.
Then we flip the default routing to make the eMMC2
the default for the SD card, so that the wifi can
start working on the Arasan.
Additional we add a menu item to enable the SDMA/ADMA2
modes on the controller.
v1->v2: Add option for user to enable/disable eMMC DMA
Only enable the emmc2 table on rpi4 &
!Arasan routing
Move emmc2 into its own SSDT and drop
second _DMA entry
Jeremy Linton (4):
Platform/RaspberryPi: Add Negative table check
Platform/RaspberryPi/Acpitables: Add eMMC2 device and tweak Arasan
Platform/RaspberryPi: User control of eMMC2 DMA
Platform/RaspberryPi: Invert default Arasan, Emmc2 routing
