Pull pin control updates from Linus Walleij:
 "Nothing stands out, apart from maybe the interesting Eswin EIC7700, a
  RISC-V SoC I've never seen before.

  Core changes:

   - Open code PINCTRL_FUNCTION_DESC() instead of defining a complex
     macro only used in one place

   - Add pinmux_generic_add_pinfunction() helper and use this in a few
     drivers

  New drivers:

   - Amlogic S7, S7D and S6 pin control support

   - Eswin EIC7700 pin control support

   - Qualcomm PMIV0104, PM7550 and Milos pin control support

     Because of unhelpful numbering schemes, the Qualcomm driver now
     needs to start to rely on SoC codenames

   - STM32 HDP pin control support

   - Mediatek MT8189 pin control support

  Improvements:

   - Switch remaining pin control drivers over to the new GPIO set
     callback that provides a return value

   - Support RSVD (reserved) pins in the STM32 driver

   - Move many fixed assignments over to pinctrl_desc definitions

   - Handle multiple TLMM regions in the Qualcomm driver"
