[PATCH v4 00/24] drm/i2c: tda998x: add DT support and other improvements

[Jean-Francois Moine]

This patch set contains various extensions to the tda998x driver:

- simplify the i2c read/write
- code cleanup and fix some small errors
- use global constants
- don't read write-only registers
- add DT support
- use irq for connection status and EDID read

- v4
    - remarks from Russell King (thank you, Russell)
	- more comments about the patches
	- remove 'fix a NULL pointer dereference'
	- get the IRQ number from the i2c client
	- remove 'get a better status of the connection'
	- split the previous 'fix the ENABLE_SPACE register'
	- add asounddef.h variables in 'change the frequence in the audio channel'
    - add 'always enable EDID read IRQ'
    - remove audio changes which will be in a next patch set about
      information exchanges with the audio subsystem
- v3
    - remarks from Russell King
	- more comments about the patches
	- change variable name instead of copy (patch 7)
	- add 'fix bad value in the AIF' (patch 8)
	- add 'fix a NULL pointer dereference' (patch 13)
	- add 'add DT documentation' (patch 16)
	- remove 'use the tda998x video format when cea mode'
	- remove 'change the video quantization
	- remove 'fix the value of the TBG_CNTRL_1 register'
	- remove 'tda998x: move the TBG_CNTRL_0 register setting'
	- change fields of the register AIP_CLKSEL (patch 19)
	- remove 'adjust the audio CTS to the mode clock'
	- don't put a comment between field definition (patch 23)
    - some more remarks may be found in the patches 10, 14, 15
    - removal of the tda codec interface which will be the subject
		of an other patch series
- v2
	- decompose patches with different topics
	- fix some bad i2c register values
	- add audio codec interface
