6fd9c99334 gpiolib: use gpiochip_dup_line_label() in for_each helpers 
Rework for_each_requested_gpio_in_range() to use the new helper to
retrieve a dynamically allocated copy of the descriptor label and free
it at the end of each iteration. We need to leverage the CLASS()'
destructor to make sure that the label is freed even when breaking out
of the loop.

27030ff787 pinctrl: qcom: fail to retrieve configuration from invalid pin groups 
The pinconf-groups debugfs file dumps each valid configuration item of
all pin groups. Some platforms and devices may have pin groups which
cannot be accessed, according to commit 691bf5d5a7 ("pinctrl: qcom:
Don't allow protected pins to be requested"). Fail for each
configuration item of an invalid pin group by checking the GPIO chip's
valid mask.

The validity of the pin group cannot be checked in the generic pinconf
dump (function "pinconf_generic_dump_one"), as it does not directly
interact with the gpiochip or the pinmux callbacks (which would give it
access to the request callback). Instead, an entry contains the ID and
name of the pingroup with no properties when all items fail.

It's naturally better to assign what it's returned to the err variable

901b277eaf pinctrl: tps6594: Add driver for TPS6594 pinctrl and GPIOs 
TI TPS6594 PMIC has 11 GPIOs which can be used
for different functions.

This patch adds a pinctrl and GPIO drivers in
order to use those functions.

6ea5c72b04 pinctrl: qcom: lpass-lpi: allow slew rate bit in main pin config register 
Existing Qualcomm SoCs have the LPASS pin controller slew rate control
in separate register, however this will change with upcoming Qualcomm
SoCs.  The slew rate will be part of the main register for pin
configuration, thus second device IO address space is not needed.

Prepare for supporting new SoCs by adding flag customizing the driver
behavior for slew rate.

Setting slew rate for each pin will grow with upcoming Qualcomm SoCs,
so split the code responsible for this into separate function for easier

76b446f5b8 pinctrl: qcom: handle intr_target_reg wakeup_present/enable bits 
New platforms uses a new set of bits to control the wakeirq
delivery to the PDC block.

The intr_wakeup_present_bit indicates if the GPIO supports
wakeirq and intr_wakeup_enable_bit enables wakeirq delivery
to the PDC block.

While the name seems to imply this only enables wakeup events,
it is required to allow interrupts events to the PDC block.

Enable this bit in the irq resource request/free if:
- gpio is in wakeirq map
- has the intr_wakeup_present_bit
- the intr_wakeup_enable_bit is set

Add driver for the pin controller in Low Power Audio SubSystem (LPASS)
of Qualcomm SM8650 SoC.

Notable differences against SM8550 LPASS pin controller:
1. Additional address space for slew rate thus driver uses
   LPI_FLAG_SLEW_RATE_SAME_REG and sets slew rate via different
   register.

2. Two new pin mux functions: qca_swr_clk and qca_swr_data

The function that a pin is muxed to can be read from the top-level
pinctrl-maps debugfs file. However, this only reflects the values that
were specified in device tree, so they will only show deviations from
the hardware default setting. Display the current pinmux setting in the
per-controller pinconf-groups debugfs file along with the rest of the
per-pin configuration settings.
