Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] CLK_MAILI_VIDEOCC incorrectly selects CLK_HAWI_GCC instead of a Maili-specific GCC or its underlying dependencies.

clk: qcom: Add support for videocc driver on Qualcomm Maili SoC

This commit adds support for the Qualcomm Maili video clock controller
driver, allowing video clients to request videocc clocks.

[Severity: Low]
Is this select intentional, or could this be a copy-paste error? It
appears CLK_MAILI_VIDEOCC is selecting the Hawi Global Clock Controller
instead of a Maili-specific GCC or its underlying dependencies.

This I plan to drop, see:
<20260708-dt-bindings-camcc-required-opps-v1-3-ae0871774210@oss.qualcomm.com>

IMO, this patch should be rebased and come after my cleanup.
