[PATCH v8 0/3] SDM670 Pin Control Driver

From: Richard Acayan
Date: Thu Oct 06 2022 - 19:22:33 EST

Changes since v7:
- remove complement_fw_reserved_gpios from patch 3

Changes since v6:
- remove bitmap_fill() call completely (original commit was 4c0efbfb2669
("pinctrl: msm: Add ability for drivers to supply a reserved GPIO list"),
original author CC'd)
- group some entries in pingroup arrays for less lines
- accumulate review tags

Changes since v5:
- remove function requirement in schema
- change "-state$" regex to double quotes in schema
- drop quotes from qcom-tlmm-state ref in dt schema

Changes since v4:
- accumulate review tag
- use --cover-letter
- this is effectively a resend

Changes since v3:
- constrain gpio-reserved-ranges to 1-75 items
- proper indentation in dt-bindings example (actually tagged this time
instead of an outdated commit)
- remove unnecessary commit reference
- rename complement_fw_reserved_gpios -> complement_fw_gpio_ranges

Changes since v2:
- remove quotes from pinctrl.yaml# in dt-bindings
- constrain gpio-reserved-ranges to 1-76 items (includes ufs_reset)
- indentation in dt-bindings example
- cite downstream kernel source
- remove MODULE_AUTHOR (most imported pinctrl drivers don't have this)

Changes since v1:
- add a field in msm_pinctrl_soc_data to accomodate the needs of the
driver and device dts
- apply changes made to existing tlmm dt documentation
- add reserved gpios array
- rename device tree compat string to qcom,sdm670-tlmm
- remove dependency on ACPI
- move MODULE_DEVICE_TABLE macro call up
- add missing pins (fixes most of the debugfs problems)
- move qup0_pins down
- add whitespace between UFS_RESET macro and pins array

This patch series adds the driver for the Qualcomm Snapdragon 670 TLMM
(Top-Level Mode Multiplexer) and introduces a new field so that SDM670-
related device trees can reserve their own gpios.
