Subject: [PATCH 037/117] dt-bindings: crypto: sun8i-ce: Add compatible for D1
|
||
|
|
|
||
|
|
D1 has a crypto engine similar to the one in other Allwinner SoCs.
|
||
|
|
Like H6, it has a separate MBUS clock gate.
|
||
|
|
|
||
|
|
It also requires the internal RC oscillator to be enabled for the TRNG
|
||
|
|
to return data. This is likely the case for earlier variants as well,
|
||
|
|
but the clock drivers for earlier SoCs did not allow disabling the RC
|
||
|
|
oscillator.
|
||
|
|
|
||
|
|
Series-changes: 2
|
||
|
|
- Add TRNG clock
|
||
|
