gpio: pxa: disable pinctrl calls for MMP_GPIO

2023-10-10T19:46:45+00:00

commit f0575116507b981e6a810e78ce3c9040395b958b upstream.

Similarly to PXA3xx and MMP2, pinctrl-single isn't capable of setting
pin direction on MMP either.

gpio: aspeed: fix the GPIO number passed to pinctrl_gpio_set_config()

2023-10-10T19:46:45+00:00

commit f9315f17bf778cb8079a29639419fcc8a41a3c84 upstream.

pinctrl_gpio_set_config() expects the GPIO number from the global GPIO
numberspace, not the controller-relative offset, which needs to be added
to the chip base.

gpio: pmic-eic-sprd: Add can_sleep flag for PMIC EIC chip

2023-10-10T19:46:39+00:00

[ Upstream commit 26d9e5640d2130ee16df7b1fb6a908f460ab004c ]

The drivers uses a mutex and I2C bus access in its PMIC EIC chip
get implementation. This means these functions can sleep and the PMIC EIC
chip should set the can_sleep property to true.

This will ensure that a warning is printed when trying to get the
value from a context that potentially can't sleep.

gpio: tb10x: Fix an error handling path in tb10x_gpio_probe()

[ Upstream commit b547b5e52a0587e6b25ea520bf2f9e03d00cbcb6 ]

If an error occurs after a successful irq_domain_add_linear() call, it
should be undone by a corresponding irq_domain_remove(), as already done
in the remove function.

gpio: tps68470: Make tps68470_gpio_output() always set the initial value

Make tps68470_gpio_output() call tps68470_gpio_set() for output-only pins
too, so that the initial value passed to gpiod_direction_output() is
honored for these pins too.

gpio: mockup: Fix mode of debugfs files

commit 0a1bb16e0fe6650c3841e611de374bfd5578ad70 upstream.

This driver's debugfs files have had a read operation since commit
2a9e27408e12 ("gpio: mockup: rework debugfs interface"), but were
still being created with write-only mode bits.  Update them to
indicate that the files can also be read.

gpio: mxc: Always set GPIOs used as interrupt source to INPUT mode

2023-02-06T06:52:37+00:00

[ Upstream commit 8e88a0feebb241cab0253698b2f7358b6ebec802 ]

Always configure GPIO pins which are used as interrupt source as INPUTs.
In case the default pin configuration is OUTPUT, or the prior stage does
configure the pins as OUTPUT, then Linux will not reconfigure the pin as
INPUT and no interrupts are received.

Always configure the interrupt source GPIO pin as input to fix the above case.

gpio: amd8111: Fix PCI device reference count leak

2022-12-14T10:30:44+00:00

[ Upstream commit 45fecdb9f658d9c82960c98240bc0770ade19aca ]

for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.

If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL
input parameter, there is no problem for the 'Device not found' branch.
For the normal path, add pci_dev_put() in amd_gpio_exit().
