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: lynxpoint: use new pinctrl GPIO helpers

2023-11-04T09:23:21+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.

Pull pin control updates from Linus Walleij:
 "No pin control core changes this time.

  New drivers:

   - Realtek RTD family pin control driver and RTD1619B, RTD1319D and
     RTD1315E subdrivers

   - Nuvoton NPCM8xx combined pin control and GPIO driver

   - Amlogic T7 pin control driver

   - Renesas RZ/G3S pin control driver

  Improvements:

   - A number of additional UART groups added to the Mediatek MT7981
     driver

   - MPM pin maps added for Qualcomm MSM8996, SM6115, SM6125 and SDM660

   - Extra GPIO banks for the Sunxi H616

   - MLSP I2C6 function support in Qualcomm MSM8226

   - Some __counted_by() annotations for dynamic arrays

   - Ongoing work to make remove() return void

   - LSBC groups and functions in the Renesas R8A7778"

pinctrl: cherryview: reduce scope of PIN_CONFIG_BIAS_HIGH_IMPEDANCE case

2023-10-11T20:40:56+00:00

We have a couple of pinconfig cases inside the braces which are meant for
PIN_CONFIG_BIAS_HIGH_IMPEDANCE case. Although it is valid C, it makes the
code less readable and prone to misinterpretation. Limit the braces to
PIN_CONFIG_BIAS_HIGH_IMPEDANCE case to avoid this.

pinctrl: cherryview: Convert to platform remove callback returning void

2023-10-11T20:40:49+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
