Subject: [PATCH v10 0/3] SDM670 Pin Control Driver

Changes since v9:
 - add arm64 kconfig check (3/3):
   https://lore.kernel.org/r/20220925112103.148836-1-krzysztof.kozlowski@linaro.org

Changes since v8:
 - change dt schema description (1/3)
 - change comment (2/3)
 - remove reference to generic pinctrl (1/3)
 - change to double quotes (1/3)

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   instead of an outdated commit)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.
