mfd: ucb1x00: Register software node for GPIO controller

2026-07-30T13:33:04+00:00

Define a static software node for the UCB1x00 GPIO controller and attach it to the core MFD device in ucb1x00_probe(). This node will also be used by the created GPIO chip. This allows machine subdrivers (such as Assabet evaluation board support) to reference the UCB1x00 GPIO controller in property entries when converting legacy platform data to software nodes, resolving pin bindings directly via the attached firmware node without relying on name matching.

mfd: db8500-prcmu: Fold dbx500 header into db8500

2026-07-30T13:32:45+00:00

Move the DBx500 PRCMU definitions into the DB8500 PRCMU header and delete the wrapper header. Convert users of simple PRCMU wrappers to call the DB8500 helpers directly. The dbx500-prcmu.h header was the result of an earlier attempt to abstract several DBx5x SoC PRCMU units to use the same abstract header. They are deleted from the kernel and this is not just causing maintenance burden and build errors. The stub code is using -ENOSYS in a way checkpatch complains about so replace these with -EINVAL while we're at it.

mfd: si476x: Modernize GPIO handling

2026-07-30T13:32:34+00:00

The SI476X driver depends on the legacy GPIO API. As it only really use a single GPIO for reset, and this can be easily converted to use a GPIO descriptor, modernize the driver. The "reset" GPIO is obtained from a device property, such as a device tree ("reset-gpios", which is standard, but this hardware has no DT bindings as of now) or a software node for static platforms. Out-of-tree users can easily adopt to providing a GPIO descriptor this way.
