[RFT,v8,0/6] ARM: pxa: GPIO descriptor conversions

Message

Duje Mihanović Oct. 11, 2023, 1:23 p.m. UTC

Hello,

Small series to convert some of the board files in the mach-pxa directory
to use the new GPIO descriptor interface.

Most notably, the am200epd, am300epd and Spitz matrix keypad among
others are not converted in this series.

- Link to v7: https://lore.kernel.org/r/[e-mail]

Changes in v7:
- Address maintainer comments:
  - Drop gpiod_put in OHCI
  - Make "struct gpio_descs *leds" in Spitz LEDs global
- Link to v6: https://lore.kernel.org/r/[e-mail]

Changes in v6:
- Address maintainer comments:
  - Use devm_gpiod_get_optional() in OHCI
  - Use gpiod_get_array() in Spitz LEDs

- Link to v5: https://lore.kernel.org/r/[e-mail]

Changes in v5:
- Address maintainer comments:
  - Rename "reset generator" GPIO to "reset"
  - Rename ads7846_wait_for_sync() to ads7846_wait_for_sync_gpio()
  - Properly bail out when requesting USB host GPIO fails
  - Use dev_err_probe() when requesting touchscreen sync GPIO fails
  - Use static gpio_desc for gumstix bluetooth reset
- Pulse gumstix bluetooth reset line correctly (assert, then deassert)
- Fix style issue in ads7846_wait_for_sync_gpio()
- Update trailers
- Link to v4: https://lore.kernel.org/r/[e-mail]

Changes in v4:

  - Drop unnecessary NULL assignments
  - Don't give up on *all* SPI devices if hsync cannot be set up
- Add Linus' Acked-by
- Link to v2: https://lore.kernel.org/r/[e-mail]

Changes in v2:
- Address maintainer comments:
  - Change mentions of function to function()
  - Drop cast in OHCI driver dev_warn() call
  - Use %pe in OHCI and reset drivers
  - Use GPIO _optional() API in OHCI driver
