Subject: [PATCH v2 0/2] arm64: allwinner: h6: Add second IOMMU reference to Cedrus
Date: Thu, 17 Nov 2022 07:07:02 +0100 [thread overview]
Message-ID: <20221117060704.367945-1-jernej.skrabec@gmail.com> (raw)
It turns out that Cedrus on H6 actually uses two IOMMU channels. Manual
mentiones two IOMMU channels, but it doesn't specify which is used when.
Page faults were also observed from both.
This series updates binding to allow up to two IOMMU channels and fixes
H6 DTSI.
Please take a look.
Best regards,
Jernej
Changes from v1:
- add minItems to binding
- add reviewed-by to DT patch
