Subject: [PATCH] DT: bcm2712: override supports-cqe to a cell
|
|
|
|
We want to be able to control the interop surface exposed by Command
|
|
Queueing across bcm2712 products to a more restrictive default, with
|
|
selectable disable and permissive behaviour.
|
|
|
|
Changing the bool to a cell lets it relay a tristate value.
|
|
|
|
Also add the override parameter to CM5 as CM5-lite may interface with
|
|
arbitrary eMMC or SD cards.
