Here is the large set of char/misc/whatever driver subsystem updates for 5.12-rc1. Over time it seems like this tree is collecting more and more tiny driver subsystems in one place, making it easier for those maintainers, which is why this is getting larger. Included in here are: - coresight driver updates - habannalabs driver updates - virtual acrn driver addition (proper acks from the x86 maintainers) - broadcom misc driver addition - speakup driver updates - soundwire driver updates - fpga driver updates - amba driver updates - mei driver updates - vfio driver updates - greybus driver updates - nvmeem driver updates - phy driver updates - mhi driver updates - interconnect driver udpates - fsl-mc bus driver updates - random driver fix - some small misc driver updates (rtsx, pvpanic, etc.) All of these have been in linux-next for a while, with the only reported issue being a merge conflict in include/linux/mod_devicetable.h that you will hit in your tree due to the dfl_device_id addition from the fpga subsystem in here. The resolution should be simple.

This driver provides access to the DPFE interface of Broadcom

provide current information about the system's RAM, for instance
|

the DRAM refresh rate. This can be used as an indirect indicator

for the DRAM's temperature. Slower refresh rate means cooler RAM,
|

higher refresh rate means hotter RAM.
