This patchset is primarily to enable iio support for the MCP2221 HID driver,
but requires several Kconfig changes and device resource management.

First attempt of this patchset is referenced here:

Link: https://lore.kernel.org/all/20220729154723.99947-1-matt.ranostay@xxxxxxxxxxxx/

Changes from v1:
* Fixing various Kconfig recursive dependencies that appear with 'imply IIO'
* Switch hid-mcp2221 driver to device managed resources for i2c support
* Reworking patchset per advice on lore.kernel.org link above

Changes from v2:
* add linux-iio list to CC

Changes from v3:
* replace .remove() tasks with devm_add_action_or_reset() in .probe()
* reschedule SRAM configuration read on failures
* add IIO_CHAN_INFO_SCALE values for ADC + DAC based on reference voltage

Matt Ranostay (5):
  i2c: muxes: ltc4306: fix future recursive dependencies
  iio: addac: stx104: fix future recursive dependencies
  iio: dac: fix future recursive dependencies
  HID: mcp2221: switch i2c registration to devm functions
  HID: mcp2221: add ADC/DAC support via iio subsystem
