Pull char / misc / other smaller driver subsystem updates from Greg KH: "Here is the large set of char, misc, and other driver subsystem updates for 5.19-rc1. The merge request for this has been delayed as I wanted to get lots of linux-next testing due to some late arrivals of changes for the habannalabs driver. Highlights of this merge are: - habanalabs driver updates for new hardware types and fixes and other updates - IIO driver tree merge which includes loads of new IIO drivers and cleanups and additions - PHY driver tree merge with new drivers and small updates to existing ones - interconnect driver tree merge with fixes and updates - soundwire driver tree merge with some small fixes - coresight driver tree merge with small fixes and updates - mhi bus driver tree merge with lots of updates and new device support - firmware driver updates - fpga driver updates - lkdtm driver updates (with a merge conflict, more on that below) - extcon driver tree merge with small updates - lots of other tiny driver updates and fixes and cleanups, full details in the shortlog. All of these have been in linux-next for almost 2 weeks with no reported problems" * tag 'char-misc-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (387 commits) habanalabs: use separate structure info for each error collect data habanalabs: fix missing handle shift during mmap habanalabs: remove hdev from hl_ctx_get args habanalabs: do MMU prefetch as deferred work habanalabs: order memory manager messages habanalabs: return -EFAULT on copy_to_user error habanalabs: use NULL for eventfd habanalabs: update firmware header habanalabs: add support for notification via eventfd habanalabs: add topic to memory manager buffer habanalabs: handle race in driver fini habanalabs: add device memory scrub ability through debugfs habanalabs: use unified memory manager for CB flow habanalabs: unified memory manager new code for CB flow habanalabs/gaudi: set arbitration timeout to a high value habanalabs: add put by handle method to memory manager habanalabs: hide memory manager page shift habanalabs: Add separate poll interval value for protocol habanalabs: use get_task_pid() to take PID habanalabs: add prefetch flag to the MAP operation ...

dt-bindings: nvmem: sfp: Add compatible binding for TA 2.1 SFPs

2022-05-09T13:46:29+00:00

Trust Architecture (TA) 2.1 devices include the LS1012A, LS1021A, LS1043A, and LS1046A. The SFP device on TA 2.1 devices is very similar to the SFP on TA 3.0 devices. The primary difference is a few fields in the control register. Add a compatible string.

dt-bindings: nvmem: sfp: Add TA_PROG_SFP supply

2022-05-09T13:46:29+00:00

The TA_PROG_SFP supply must be enabled to program the fuses, and disabled to read the fuses (such as at power-on-reset). On many boards, this supply is controlled by a jumper. The user must manually insert or remove it at the appropriate time in the programming process. However, on other boards this supply is controlled by an FPGA or a GPIO. In these cases, the driver can automatically enable and disable it as necessary.

dt-bindings: nvmem: sfp: Add clock properties

2022-05-09T13:46:29+00:00

To program fuses, it is necessary to set the fuse programming time. This is determined based on the value of the platform clock. Add a clock property. Because this property is necessary for programming, it is made mandatory. Since these bindings have not yet been present in a stable release (though they are on track for 5.18), it is not an ABI break to change them in this manner.

dt-bindings: nvmem: add U-Boot environment variables binding

2022-03-23T23:10:00+00:00

U-Boot uses environment variables for storing device setup data. It usually needs to be accessed by a bootloader, kernel and often user-space. This binding allows describing environment data located in a raw flash partition. It's treated as NVMEM device and can be reused later for other storage devices. Using DT should be cleaner than hardcoding & duplicating such info in multiple places. Bootloader & kernel can share DTS and user-space can try reading it too or just have correct data exposed by a kernel. A custom "compatible" string allows system to automatically load relevant NVMEM driver but phandle can be also used for reading raw location.

dt-bindings: nvmem: brcm,nvram: add basic NVMEM cells

2022-03-18T13:08:36+00:00

NVRAM doesn't have cells at hardcoded addresses. They are stored in internal struct (custom & dynamic format). It's still important to define relevant cells in DT so NVMEM consumers can reference them. Update binding to allow including basic cells as NVMEM device subnodes.
