pinctrl: Switch back to struct platform_driver::remove()

2024-10-11T19:45:47+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/pinctrl to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

pinctrl: rockchip: improve error message for incorrect rockchip,pins property

2024-10-02T14:12:00+00:00

If one improperly writes a rockchip,pins property, the pinctrl driver
basically just states that one in the myriad of pinctrl nodes is
improper but does not tell you which one.

Instead, let's print the full name of the Device Tree node that is
improper as well as provide more context on what the expected content
is.

Note that this should be rather unnecessary if one reads the output of
the dtbs_check as it would be highlighted as an error.

pinctrl: rockchip: correct RK3328 iomux width flag for GPIO2-B pins

2024-08-24T14:39:51+00:00

The base iomux offsets for each GPIO pin line are accumulatively
calculated based off iomux width flag in rockchip_pinctrl_get_soc_data.
If the iomux width flag is one of IOMUX_WIDTH_4BIT, IOMUX_WIDTH_3BIT or
IOMUX_WIDTH_2BIT, the base offset for next pin line would increase by 8
bytes, otherwise it would increase by 4 bytes.

Despite most of GPIO2-B iomux have 2-bit data width, which can be fit
into 4 bytes space with write mask, it actually take 8 bytes width for
whole GPIO2-B line.

Commit e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328
GPIO2-B pins") wrongly set iomux width flag to 0, causing all base
iomux offset for line after GPIO2-B to be calculated wrong. Fix the
iomux width flag to IOMUX_WIDTH_2BIT so the offset after GPIO2-B is
correctly increased by 8, matching the actual width of GPIO2-B iomux.
