Merge tag 'char-misc-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc driver updates from Greg KH:
 "Here is the large set of char/misc and other driver subsystem changes
  for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of
  new driver development and minor fixes.

  Highlights include:

   - fastrpc driver updates

   - iio new drivers and updates

   - habanalabs driver updates for new hardware and features

   - slimbus driver updates

   - speakup module parameters added to aid in boot time configuration

   - i2c probe_new conversions for lots of different drivers

   - other small driver fixes and additions

  One semi-interesting change in here is the increase of the number of
  misc dynamic minors available to 1048448 to handle new huge-cpu
  systems.

  All of these have been in linux-next for a while with no reported
  problems"

Description:

		CBMEM is a downwards-growing memory region created by Coreboot,

		and contains tagged data structures to be shared with payloads

		in the boot process and the OS.  Each CBMEM entry is given a

		directory in /sys/bus/coreboot/devices based on its id.

		A list of ids known to Coreboot can be found in the coreboot

		source tree at

		that this file does not support mmap(), as coreboot

		does not guarantee that the data will be page-aligned.



		The mode of this file is 0600.  While there shouldn't be

		anything security-sensitive contained in CBMEM, read access

		requires root privileges given this is exposing a small subset

		of physical memory.

Description:

		Reading returns a list with the possible filter modes.



		  * "sinc4"       - Sinc 4. Excellent noise performance. Long

                    1st conversion time. No natural 50/60Hz rejection.



		  * "sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion

		    time.



		  * "sinc3"	      - Sinc3. Moderate 1st conversion time.

		    Good noise performance.



		  * "sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling

		    frequency of 50Hz, achieves simultaneous 50Hz and 60Hz

		    rejection.



		  * "sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion

		    time. Best used with a sampling frequency of at least

		    216.19Hz.
