Merge tag 'char-misc-5.13-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 big set of various smaller driver subsystem updates for 5.13-rc1. Major bits in here are: - habanalabs driver updates - hwtracing driver updates - interconnect driver updates - mhi driver updates - extcon driver updates - fpga driver updates - new binder features added - nvmem driver updates - phy driver updates - soundwire driver updates - smaller misc and char driver fixes and updates. - bluetooth driver bugfix that maintainer wanted to go through this tree. All of these have been in linux-next with no reported issues" * tag 'char-misc-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (330 commits) bluetooth: eliminate the potential race condition when removing the HCI controller coresight: etm-perf: Fix define build issue when built as module phy: Revert "phy: ti: j721e-wiz: add missing of_node_put" phy: ti: j721e-wiz: Add missing include linux/slab.h phy: phy-twl4030-usb: Fix possible use-after-free in twl4030_usb_remove() stm class: Use correct UUID APIs intel_th: pci: Add Alder Lake-M support intel_th: pci: Add Rocket Lake CPU support intel_th: Consistency and off-by-one fix intel_th: Constify attribute_group structs intel_th: Constify all drvdata references stm class: Remove an unused function habanalabs/gaudi: Fix uninitialized return code rc when read size is zero greybus: es2: fix kernel-doc warnings mei: me: add Alder Lake P device id. dw-xdata-pcie: Update outdated info and improve text format dw-xdata-pcie: Fix documentation build warns fbdev: zero-fill colormap in fbcmap.c firmware: qcom-scm: Fix QCOM_SCM configuration speakup: i18n: Switch to kmemdup_nul() in spk_msg_set() ...

+What: /sys/class/misc/drivers/dw-xdata-pcie.<device>/write
+Date: April 2021
+KernelVersion: 5.13
+Contact: Gustavo Pimentel <gustavo.pimentel@synopsys.com>
+Description: Allows the user to enable the PCIe traffic generator which
+ will create write TLPs frames - from the Root Complex to the
+ Endpoint direction or to disable the PCIe traffic generator
+ in all directions.
+
+ Write y/1/on to enable, n/0/off to disable
+
+ Usage e.g.
+ echo 1 > /sys/class/misc/dw-xdata-pcie.<device>/write
+ or
+ echo 0 > /sys/class/misc/dw-xdata-pcie.<device>/write
+
+ The user can read the current PCIe link throughput generated
+ through this generator in MB/s.
+
+ Usage e.g.
+ cat /sys/class/misc/dw-xdata-pcie.<device>/write
+ 204
+
+ The file is read and write.
