[PATCH v5 0/5] Add pin control support for lpass sc7280
This patch series is to split lpass variant common pin control functions and SoC specific functions and to add lpass sc7280 pincontrol support. It also Adds dt-bindings for lpass sc7280 lpass lpi pincontrol.
Changes Since V4: -- Update commit message and description of the chip specific extraction patch. -- Sort macros in kconfig and makefile. -- Update optional clock voting to conditional clock voting. -- Fix typo errors. -- Move to quicinc domain email id's. Changes Since V3: -- Update separate Kconfig fields for sm8250 and sc7280. -- Update module license and description. -- Move static variables to corresponding .c files from header file.
Changes Since V2: -- Add new dt-bindings for sc7280 lpi driver. -- Make clock voting change as separate patch. -- Split existing pincontrol driver and make common functions as part of separate file. -- Rename lpass pincontrol lpi dt-bindings to sm8250 specific dt-bindings Changes Since V1: -- Make lpi pinctrl variant data structure as constant -- Add appropriate commit message -- Change signedoff by sequence.

I remember in my previous review that I requested you to use git mv for renaming this
Yes. Created patch with "git mv" and commit. Not sure why diff is not as expected.
The 'git mv' is not what matters. You need the -M option for git-format-patch/send-email. There's a config option you can enable that by default.

Actually this also needs as separate patch. these patches will do as separate series.

Of course, that's why I put the second sentence after the question in my reply.
Add pin control support for SC7280 LPASS LPI.

Quoting Srinivasa Rao Mandadapu (2021-12-07 07:35:34)
This patch series is to split lpass variant common pin control functions and SoC specific functions and to add lpass sc7280 pincontrol support. It also Adds dt-bindings for lpass sc7280 lpass lpi pincontrol.
What ensures that the LPI pins are being muxed out on the pads of the SoC? There's the eGPIO support in the tlmm driver, which seems to let us override the LPI pins and mux them away from this pinctrl device to the tlmm pinctrl device. Should this driver be requesting gpios from tlmm and making sure they're not muxed away to tlmm so we don't have conflicts?
