Immutable branch between the GPIO, ASoC and regulator trees for v6.19-rc1

From: Bartosz Golaszewski <[email protected]>

Hi Mark!

Please pull the following changes into the ASoC and regulator trees as a prerequisite to applying patches 8-10 for v6.19-rc1 from the series improving support for shared GPIOs[1].

Please note that there's a small conflict between v6.18-rc1 and my gpio/for-next branch where gpio_chip_hwgpio() has been renamed to gpiod_hwgpio().

In linux-next it can be fixed like this:

 			pr_debug("Device %s acquired a reference to the shared GPIO %u owned by %s\n",
-				 dev_name(&adev->dev), gpio_chip_hwgpio(shared_desc->desc),
+				 dev_name(&adev->dev), gpiod_hwgpio(shared_desc->desc),
 				 gpio_device_get_label(shared_desc->desc->gdev));
 

Thanks!

arm64: select HAVE_SHARED_GPIOS for ARCH_QCOM (2025-11-17 10:16:51 +0100)

----------------------------------------------------------------
Immutable branch between the GPIO, ASoC and regulator trees for v6.19-rc1

Add better support for GPIOs shared by multiple consumers.
