pinctrl: pistachio: fix use of irq_of_parse_and_map()

2022-05-12T10:14:55+00:00

[ Upstream commit 0c9843a74a85224a89daa81fa66891dae2f930e1 ]

The irq_of_parse_and_map() function returns 0 on failure, and does not
return an negative value.

pinctrl: pinconf-generic: Print arguments for bias-pull-*

2022-04-20T07:06:40+00:00

commit 188e5834b930acd03ad3cf7c5e7aa24db9665a29 upstream.

The bias-pull-* properties, or PIN_CONFIG_BIAS_PULL_* pin config
parameters, accept optional arguments in ohms denoting the strength of
the pin bias.

Print these values out in debugfs as well.

pinctrl/rockchip: Add missing of_node_put() in rockchip_pinctrl_probe

pinctrl/amd: Add device HID for new AMD GPIO controller

2021-07-20T14:21:09+00:00

commit 1ca46d3e43569186bd1decfb02a6b4c4ddb4304b upstream.

Add device HID AMDI0031 to the AMD GPIO controller driver match table.
This controller can be found on Microsoft Surface Laptop 4 devices and
seems similar enough that we can just copy the existing AMDI0030 entry.

pinctrl: baytrail: Avoid clearing debounce value when turning it off

2020-12-29T12:44:50+00:00

[ Upstream commit 0b74e40a4e41f3cbad76dff4c50850d47b525b26 ]

Baytrail pin control has a common register to set up debounce timeout.
When a pin configuration requested debounce to be disabled, the rest
of the pins may still want to have debounce enabled and thus rely on
the common timeout value. Avoid clearing debounce value when turning
it off for one pin while others may still use it.
