Merge tag 'char-misc-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char / misc and other driver updates from Greg KH:
 "Here is the "big" set of char/misc and other driver subsystem changes
  for 6.11-rc1. Nothing major in here, just loads of new drivers and
  updates. Included in here are:

   - IIO api updates and new drivers added

   - wait_interruptable_timeout() api cleanups for some drivers

   - MODULE_DESCRIPTION() additions for loads of drivers

   - parport out-of-bounds fix

   - interconnect driver updates and additions

   - mhi driver updates and additions

   - w1 driver fixes

   - binder speedups and fixes

   - eeprom driver updates

   - coresight driver updates

   - counter driver update

   - new misc driver additions

   - other minor api updates

  All of these, EXCEPT for the final Kconfig build fix for 32bit
  systems, have been in linux-next for a while with no reported issues.
  The Kconfig fixup went in 29 hours ago, so might have missed the
  latest linux-next, but was acked by everyone involved"

KernelVersion:	6.11

Contact:	Marek Vasut <marex@denx.de>

Description:

		This read/write attribute allows users to set read-write

		devices as read-only and back to read-write from userspace.

		This can be used to unlock and relock write-protection of

		devices which are generally locked, except during sporadic

		programming operation.

		Read returns '0' or '1' for read-write or read-only modes

		respectively.

		Write parses one of 'YyTt1NnFf0', or [oO][NnFf] for "on"

		and "off", i.e. what kstrbool() supports.

		Note: This file is only present if CONFIG_NVMEM_SYSFS

		is enabled.

Date:		June 2024

KernelVersion:	6.11

Contact:	Gerhard Engleder <eg@keba.com>

Description:	Flag which signals if FPGA shall keep or reload configuration

		bitstream on reset. Normal FPGA behavior and default is to keep

		configuration bitstream and to only reset the configured logic.



		Reloading configuration on reset enables an update of the

		configuration bitstream with a simple reboot. Otherwise it is

		necessary to power cycle the device to reload the new

		configuration bitstream.



		This file is read/write. The values are as follows:

		1 = keep configuration bitstream on reset, default

		0 = reload configuration bitstream on reset

Description:

		Accelerometer power mode. Setting this attribute will set the

		requested power mode to use if the ODR support it. If ODR

		support only 1 mode, power mode will be enforced.

		Reading this attribute will return the current accelerometer

		power mode if the sensor is on, or the requested value if the

		sensor is off. The value between real and requested value can

		be different for ODR supporting only 1 mode.
