Pull pin control updates from Linus Walleij:
"An especially linear and sparse improvement and new drivers release.
Nothing exciting. The biggest change in Bartosz changes to make
gpiochip set/get calls return error codes (something we should have
fixed ages ago but is now finally getting fixed.)
Core changes:
- Add the devres devm_pinctrl_register_mappings() call that can
register some pin control machine mappings and have them go away
with the associated device
New drivers:
- Support for the Mediatek MT6893 and MT8196 SoCs
- Support for the Renesas RZ/V2N SoC
- Support for the NXP Freescale i.MX943 SoC
Improvements:
- Per-SoC suspend/resume callbacks in the Samsung drivers
- Set all pins as input (High-Z) at probe in the MCP23S08 driver
- Switch most GPIO chips to use the setters/getters with a return
value
- EGPIO support in the Qualcomm QCM2290 driver
- Fix up the number of available GPIO lines in Qualcomm QCS8300 and
QCS615"
