[PATCH v6 0/8] Support for the NPU in Vim3

[PATCH v6 0/8] Support for the NPU in Vim3

[Tomeu Vizoso]

Hi,

This series adds support for the Verisilicon VIPNano-QI NPU in the A311D
as in the VIM3 board.

The IP is very closely based on previous Vivante GPUs, so the etnaviv
kernel driver works basically unchanged.

The userspace part of the driver is being reviewed at:

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/18986

v2: Move reference to RESET_NNA to npu node (Neil)
v3: Fix indentation mistake (Neil)
v4: Add warning when etnaviv probes on a NPU (Lucas)
v5: Reorder HWDB commit to be the last (Lucas)
v6: Add patch to move the power domain to the SoC-specific dtsi (Neil)

Regards,

Tomeu

[PATCH v6 1/8] dt-bindings: reset: meson-g12a: Add missing NNA reset

[Tomeu Vizoso]

Doesn't appear in the TRM I have, but it is used by the downstream
galcore driver.

[PATCH v6 8/8] arm64: dts: Fix NPU power domain references in Amlogic G12-based SoCs

The power sequence is different between SoCs in that family, so get the
right bits for each one.

Tomeu, I think until the user-space stack is clean this should be removed
and left disabled.

I can fix this while applying if you want,

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.3/bindings)

[1/8] dt-bindings: reset: meson-g12a: Add missing NNA reset
      https://git.kernel.org/amlogic/c/a439267609f9d57b15991c55550956d7cc5404d8
[2/8] dt-bindings: power: Add G12A NNA power domain
      https://git.kernel.org/amlogic/c/340ea839b4306335bd627fe0dd6789df803aef58

These changes has been applied on the intermediate git tree [1].

The v6.3/bindings branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
