Merge tag 'pinctrl-v5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.4 kernel cycle:

  Core changes:

   - Fix errors in example code in the documentation.

  New drivers:

   - Add support for JZ4760, JZ4760B, X1000, X1000E and X1500 to the
     Ingenic driver.

   - Support Cirrus Logic Madera CS47L92 and CS47L15.

   - Support Allwinner Sunxi V3S.

   - Support Aspeed 2600 BMC.

   - Support Qualcomm SC7180.

   - Support Marvell MVEBU CS115.

  Driver improvements:

   - Clean up a few drivers to use the devm_platform_ioremap_resource()
     helper.

   - Pass the irqchip when registering the gpio_chip in some pin
     controllers that are also GPIO controllers.

   - Support suspend/resume in the Tegra driver.

   - Support pull-up on the Broadcom BCM2711.

   - The Intel driver can now request locked pads.

   - Fix the UFS reset pin in the Qualcomm SDM845 driver"
