Merge tag 'char-misc-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc and other driver subsystem updates from Greg KH:
 "Here is the big set of char/misc and other driver subsystem updates
  for 6.10-rc1. Nothing major here, just lots of new drivers and updates
  for apis and new hardware types. Included in here are:

   - big IIO driver updates with more devices and drivers added

   - fpga driver updates

   - hyper-v driver updates

   - uio_pruss driver removal, no one uses it, other drivers control the
     same hardware now

   - binder minor updates

   - mhi driver updates

   - excon driver updates

   - counter driver updates

   - accessability driver updates

   - coresight driver updates

   - other hwtracing driver updates

   - nvmem driver updates

   - slimbus driver updates

   - spmi driver updates

   - other smaller misc and char driver updates

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

Description:    Writing a non-zero value to this file will force devices to

                enter EDL (Emergency Download) mode. This entry only exists for

                devices capable of entering the EDL mode using the standard EDL

                triggering mechanism defined in the MHI spec v1.2. Once in EDL

                mode, the flash programmer image can be downloaded to the

                device to enter the flash programmer execution environment.

                This can be useful if user wants to use QDL (Qualcomm Download,

                which is used to download firmware over EDL) to update firmware.
