Merge tag 'char-misc-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc 

Pull char/misc/IIO driver updates from Greg KH:
 "Here is the big set of char/misc/iio driver updates for 6.19-rc1. Lots
  of stuff in here including:

   - lots of IIO driver updates, cleanups, and additions

   - large interconnect driver changes as they get converted over to a
     dynamic system of ids

   - coresight driver updates

   - mwave driver updates

   - binder driver updates and changes

   - comedi driver fixes now that the fuzzers are being set loose on
     them

   - nvmem driver updates

   - new uio driver addition

   - lots of other small char/misc driver updates, full details in the
     shortlog

  All of these have been in linux-next for a while now"

What:		/sys/bus/pci/drivers/uio_pci_sva/<pci_dev>/pasid

Description:

		Process Address Space ID (PASID) assigned by IOMMU driver to

		the device for use with Shared Virtual Addressing (SVA).



		This read-only attribute exposes the PASID (A 20-bit identifier

		used in PCIe Address Translation Services and iommu table walks)

		allocated by the IOMMU driver during sva device binding.



		User-space UIO applications must read this attribute to obtain

		the PASID and program it into the device's configuration registers.

		This enables the device to perform DMA using user-space virtual

		address, with address translation handled by IOMMU.



		UIO User-space applications must:

		- Opening device and Mapping the device's register space via /dev/uioX

		(This triggers the IOMMU driver to allocate the PASID)

		- Reading the PASID from sysfs

		- Writing the PASID to a device-specific register (with example offset)

		The code may be like:



		map = mmap(..., "/dev/uio0", ...);



		f = fopen("/sys/.../pasid", "r");

		fscanf(f, "%d", &pasid);



		map[REG_PASID_OFFSET] = pasid;
