Subject: [PATCH 052/117] iommu/sun50i: Add support for the D1 variant
|
||
|
|
|
||
|
|
D1 contains an IOMMU similar to the one in the H6 SoC, but the D1
|
||
|
|
variant has no external reset signal. It also has some register
|
||
|
|
definition changes, but none that affect the current driver.
|
||
|
