Subject: [GIT PULL 6/6] soc: driver updates for 6.19, part 2
The following changes since commit 6a23ae0a96a600d1d12557add110e0bb6e32730c:

Merge tag 'samsung-drivers-6.19-2-late' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into soc/drivers-late (2025-12-05 15:31:33 +0100)

soc: driver updates for 6.19, part 2
These updates came a little late, or were based on a later 6.18-rc
tag than the others:
- A new driver for cache management on cxl devices with memory shared
in a coherent cluster. This is part of the drivers/cache/ tree, but
unlike the other drivers that back the dma-mapping interfaces, this
one is needed only during CPU hotplug.
- A shared branch for reset controllers using swnode infrastructure
- Added support for new SoC variants in the Amlogic soc_device
identification
- Minor updates in Freescale, Microchip, Samsung, and Apple SoC drivers
