Subject: [PATCH v1 00/15] auxdisplay: linedisp: Clean up and add new driver

Add a new initial driver for Maxim MAX6958/6959 chips.
While developing that driver I realised that there is a lot
of duplication between ht16k33 and a new one. Hence set of
cleanups and refactorings.

Note, the new driver has minimum support of the hardware and
I have plans to cover more features in the future.

Andy Shevchenko (15):
  auxdisplay: img-ascii-lcd: Make container_of() no-op for struct
    linedisp
  auxdisplay: linedisp: Free allocated resources in ->release()
  auxdisplay: linedisp: Use unique number for id
  auxdisplay: linedisp: Unshadow error codes in ->store()
  auxdisplay: linedisp: Add missing header(s)
  auxdisplay: linedisp: Move exported symbols to a namespace
  auxdisplay: linedisp: Group line display drivers together
  auxdisplay: linedisp: Provide struct linedisp_ops for future extension
  auxdisplay: linedisp: Add support for overriding character mapping
  auxdisplay: linedisp: Provide a small buffer in the struct linedisp
  auxdisplay: ht16k33: Move ht16k33_linedisp_ops down
  auxdisplay: ht16k33: Switch to use line display character mapping
  auxdisplay: ht16k33: Use buffer from struct linedisp
  dt-bindings: auxdisplay: Add Maxim MAX6958/6959
  auxdisplay: Add driver for MAX695x 7-segment LED controllers
