[PATCH v4 0/4] riscv: sophgo: cv18xx: Add reset generator support

Posted by Inochi Amaoto 3 months, 3 weeks ago

Like SG2042, CV1800 Series SoCs also have simple bit reset generator.
Add necessary code and bindings for it.

Changes from v4:
1. patch 1: convert the compatible as entry of enum.
1. patch 2, 3: apply Alexander's tag.
1. patch 3: apply Junhui's tag.

Changes from v2:
1. patch 3: fix wrong reset ID.

Changes from v1:
1. rebase to v6.16-rc1
2. patch 1: apply Rob's tag
3. patch 3: fix wrong reset ID

I wonder if the binding and driver can be merged, as many devices
require reset to functional normally. If these two are taken, I
can take the dts change.
