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" * tag 'char-misc-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (330 commits) misc: Kconfig: exclude mrvl-cn10k-dpi compilation for 32-bit systems misc: delete Makefile.rej binder: fix hang of unregistered readers misc: Kconfig: add a new dependency for MARVELL_CN10K_DPI virtio: add missing MODULE_DESCRIPTION() macro agp: uninorth: add missing MODULE_DESCRIPTION() macro spmi: add missing MODULE_DESCRIPTION() macros dev/parport: fix the array out-of-bounds risk samples: configfs: add missing MODULE_DESCRIPTION() macro misc: mrvl-cn10k-dpi: add Octeon CN10K DPI administrative driver misc: keba: Fix missing AUXILIARY_BUS dependency slimbus: Fix struct and documentation alignment in stream.c MAINTAINERS: CC dri-devel list on Qualcomm FastRPC patches misc: fastrpc: use coherent pool for untranslated Compute Banks misc: fastrpc: support complete DMA pool access to the DSP misc: fastrpc: add missing MODULE_DESCRIPTION() macro misc: fastrpc: Add missing dev_err newlines misc: fastrpc: Use memdup_user() nvmem: core: Implement force_ro sysfs attribute nvmem: Use sysfs_emit() for type attribute ...

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. | ||

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. | ||
