pinctrl: rockchip: add pinmux_ops.gpio_set_direction callback

2022-10-24T07:56:51+00:00

commit 4635c0e2a7f7f3568cbfccae70121f9835efa62c upstream.

Before the split of gpio and pinctrl sections in their own driver,
rockchip_set_mux was called in pinmux_ops.gpio_set_direction for
configuring a pin in its GPIO function.

This is essential for cases where pinctrl is "bypassed" by gpio
consumers otherwise the GPIO function is not configured for the pin and
it does not work. Such was the case for the sysfs/libgpiod userspace
GPIO handling.

Let's re-implement the pinmux_ops.gpio_set_direction callback so that
the gpio subsystem can request from the pinctrl driver to put the pin in
its GPIO function.

pinctrl: sunxi: Fix name for A100 R_PIO

[ Upstream commit 76648c867c6c03b8a468d9c9222025873ecc613d ]

The name of A100 R_PIO driver should be sun50i-a100-r-pinctrl,
not sun50iw10p1-r-pinctrl.

pinctrl: qcom: sc8180x: Fix wrong pin numbers

[ Upstream commit 48ec73395887694f13c9452b4dcfb43710451757 ]

pinctrl: qcom: sc8180x: Fix gpio_wakeirq_map

2022-09-23T12:14:01+00:00

[ Upstream commit 6124cec530c7d8faab96d340ab2df5161e5d1c8a ]

Currently in the wakeirq_map, gpio36 and gpio37 have the same wakeirq
number, resulting in gpio37 being unable to trigger interrupts.
It looks like that this is a typo in the wakeirq map. So fix it.

pinctrl: intel: Check against matching data instead of ACPI companion

2022-08-25T09:45:44+00:00

[ Upstream commit c551bd81d198bf1dcd4398d5454acdc0309dbe77 ]

In some cases we may get a platform device that has ACPI companion
which is different to the pin control described in the ACPI tables.
This is primarily happens when device is instantiated by board file.

In order to allow this device being enumerated, refactor
intel_pinctrl_get_soc_data() to check the matching data instead of
ACPI companion.

pinctrl: sunxi: Add I/O bias setting for H6 R-PIO

2022-08-25T09:45:18+00:00

commit fc153c8f283bf5925615195fc9d4056414d7b168 upstream.

H6 requires I/O bias configuration on both of its PIO devices.
Previously it was only done for the main PIO.

The setting for Port L is at bit 0, so the bank calculation needs to
account for the pin base. Otherwise the wrong bit is used.
