…el/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.8 kernel cycle.

  It's just really boring this time. Zero core changes. Just linear
  development, cleanups and misc noncritical fixes. Some new drivers for
  very new Qualcomm and Intel chips.

  New drivers:

   - Intel Jasper Lake support.

   - NXP Freescale i.MX8DXL support.

   - Qualcomm SM8250 support.

   - Renesas R8A7742 SH-PFC support.

  Driver improvements:

   - Severe cleanup and modernization of the MCP23s08 driver.

   - Mediatek driver modularized.

   - Setting config supported in the Meson driver.

   - Wakeup support for the Broadcom BCM7211"
