pinctrl: mediatek: Drop bogus slew rate register range for MT8192

2024-03-26T22:18:31+00:00

[ Upstream commit e15ab05a6b3ed42f2f43f8bd1a1abdbde64afecd ]

The MT8192 does not support configuring pin slew rate. This is evident
from both the datasheet, and the fact that the driver points the slew
rate register range at the GPIO direction register range.

Drop the bogus setting.

pinctrl: mediatek: common: drop the wrappers around pinctrl_gpio_direction_input()

2023-11-04T09:23:23+00:00

pinctrl_gpio_direction_input() now has the same signature as the
wrappers around it so we can drop them.

treewide: rename pinctrl_gpio_direction_output_new()

2023-11-04T09:23:22+00:00

Now that pinctrl_gpio_direction_output() is no longer used, let's drop
the '_new' suffix from its improved variant.

pinctrl: mediatek: paris: use new pinctrl GPIO helpers

2023-11-04T09:23:20+00:00

Replace the pinctrl helpers taking the global GPIO number as argument
with the improved variants that instead take a pointer to the GPIO chip
and the controller-relative offset.

pinctrl: mediatek: moore: handle mtk_hw_set_value() errors in mtk_pinmux_set_mux()

2023-09-27T08:39:29+00:00

mtk_pinmux_set_mux() doesn't check the result of mtk_hw_set_value()
despite it may return a negative error code. Propagate error code
to caller functions.
