gpio: qcom_pmic: drop gpio-count property

2024-01-16T12:26:53+00:00

This property is not part of the dt bindings and all boards use the new
gpio-ranges property instead. Drop support for this.

msm_gpio: Add support for Qualcomm IPQ40xx

2020-07-29T12:43:40+00:00

Snapdragon SoCs and IPQ40xx use common TLMM IP,
so existing driver supports IPQ40xx as well.

So lets simply add a compatible for IPQ40xx.

dt-bindings: gpio: alignment with kernel v5.3

2020-04-17T03:06:54+00:00

Update the binding file for gpio, it is just an alignment
with kernel v5.3.
The U-Boot code example for gpio-hog (not directly linked
to binding) is moved in a new file doc/README.gpio.

dt-bindings: gpio: document the new pull-up/pull-down flags

2020-04-17T03:06:54+00:00

This commit extends the flags that can be used in GPIO specifiers to
indicate if a pull-up resistor or pull-down resistor should be
enabled.

It is the backport of linux commit ede033e1e863c ('dt-bindings:
gpio: document the new pull-up/pull-down flags')
from Thomas Petazzoni 
and integrated in v5.1-rc1

gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal

2020-03-31T14:06:52+00:00

Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.

This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.

Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.

It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit 69b921acae8a)

x86: p2sb: Drop 'apl' prefix

2020-03-05T10:25:21+00:00

Drop the Apollo Lake prefix 'apl' from the functions, types and
variables in the P2SB driver.

The P2SB is not Apollo Lake specific, and as such it was moved in
commit 2999846c1127 ("x86: Move P2SB from Apollo Lake to a more generic
location") from the Apollo Lake folder to the intel_common folder.

Add a GPIO driver which uses the pinctrl driver to access the pad
