Subject: [PATCH v5 0/3] SDM670 Pin Control Driver

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instead of an outdated commit)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.

Subject: [PATCH v5 1/3] dt-bindings: pinctrl: qcom: add sdm670 pinctrl

There is a new driver for the Snapdragon 670 TLMM (Top-Level Mode
Multiplexer). Document it.

Adapted from qcom,sm6350-pinctrl.yaml.

You can drop it (and move the ref just after description). This will be
handled with common schema:
https://lore.kernel.org/linux-devicetree/[email protected]/T/#m48dedb167f16315dbacd5c56c57f9033fe28a5d9

This however is not a dependency - if you remove these lines, your patch
can still be applied independently of mine.
