pinctrl: renesas: r8a77990: JTAG pins do not have pull-down capabilities

2021-07-14T15:06:56+00:00

[ Upstream commit 702a5fa2fe4d7e7f28fed92a170b540acfff9d34 ]

Hence remove the SH_PFC_PIN_CFG_PULL_DOWN flags from their pin
descriptions.

R-Car Gen3 Hardware Manual Errata for Rev. 0.52 of Nov 30, 2016, added
the configuration bit for bias pull-down control for the PRESET# pin on
R-Car M3-W.  Add driver support for controlling pull-down on this pin.

pinctrl: stm32: fix the reported number of GPIO lines per bank

2021-06-18T12:56:54+00:00

Each GPIO bank supports a variable number of lines which is usually 16, but
is less in some cases : this is specified by the last argument of the
"gpio-ranges" bank node property.
Report to the framework, the actual number of lines, so the libgpiod
gpioinfo command lists the actually existing GPIO lines.

pinctrl: microchip-sgpio: Put fwnode in error case during ->probe()

2021-06-18T09:17:47+00:00

device_for_each_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.

pinctrl: qcom: Make it possible to select SC8180x TLMM

2021-06-09T11:15:20+00:00

It's currently not possible to select the SC8180x TLMM driver, due to it
selecting PINCTRL_MSM, rather than depending on the same. Fix this.

pinctrl: ralink: rt2880: avoid to error in calls is pin is already enabled

2021-06-07T07:08:53+00:00

In 'rt2880_pmx_group_enable' driver is printing an error and returning
-EBUSY if a pin has been already enabled. This begets anoying messages
in the caller when this happens like the following:

rt2880-pinmux pinctrl: pcie is already enabled
mt7621-pci 1e140000.pcie: Error applying setting, reverse things back

To avoid this just print the already enabled message in the pinctrl
driver and return 0 instead to not confuse the user with a real
bad problem.

linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in

2021-05-08T15:29:45+00:00

 is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.

IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.

Also,  is no longer self-contained because NULL is
defined in .

Move IF_ENABLED() out to  as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in .

Merge tag 'pinctrl-v5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2021-04-30T20:04:30+00:00

Pull pin control updates from Linus Walleij:
"There is a lot going on!

Core changes:

- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the device
tree. The device tree is a functional programming language and does
not imply any order, so the right thing is for the pin control core
to provide these semantics.

- Add a new pinmux-select debugfs file which makes it possible to go
in and select functions for a pin manually (iteratively, at the
prompt) for debugging purposes.

- Fixes to gpio regmap handling for a new pin control driver making
use of regmap-gpio.

- Use octal permissions on debugfs files.

New drivers:

- A massive rewrite of the former custom pin control driver for MIPS
Broadcom devices to instead use the pin control subsystem. New pin
control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368,
BCM63268 and BCM6318 SoC variants are implemented.

- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B
in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are
supported.

- Support for the Rockchip RK3568/RK3566 pin controller.

- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000.

- Support for Mediatek MTK8195.

- Add a new Xilinx ZynqMP pin control driver.

Driver improvements and non-urgent fixes:

- Modularization and improvements of the Rockchip drivers.

- Some new pins added to the description of new Renesas SoCs.

- Clarifications of the GPIO base calculation in the Intel driver.

- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.

- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.

- Support for ACPI probing of the Qualcomm SC8180x.

- Fix interrupt clear status on rockchip

- Fix some missing pins on the Ingenic JZ4770, some semantic fixes
for the behaviour of the Ingenic pin controller. Add DMIC pins for
JZ4780, X1000, X1500 and X1830.

- A slew of janitorial like of_node_put() calls"
