Subject: [PATCH 0985/1085] DTS: bcm2712: defer SDIO1 CQE selection to the
|
||
|
|
board dtb
|
||
|
|
|
||
|
|
Command Queueing on Linux with SD cards is new, with the potential to cause
|
||
|
|
filesystem corruption due to bugs in software or card firmware(s).
|
||
|
|
|
||
|
|
Default to disabled unless a) we know the interface connects to an eMMC
|
||
|
|
device or b) we want it switched on.
|
||
