Hi Mauro, Hans,

This patch set contains two drivers
 - Renesas R-Car Digital Radio Interface (DRIF) driver
 - Maxim's MAX2175 RF to Bits tuner driver

These patches were based on top of media_tree.
commit: 47f910f0e0deb880c2114811f7ea1ec115a19ee4

These two drivers combined together expose a V4L2 SDR device that is compliant
with the V4L2 framework [1]. Agreed review comments are incorporated in this
series.

The rcar_drif device is modelled using "renesas,bonding" property. The
discussion on this property is available here [2].

Change history:

v7 -> v8:
 - Added MAINTAINERS entry for both drivers
 - Fixed smatch warnings on both drivers (Thank you Hans)

v6 -> v7:
 - MAX2175 I2S enable/disable control is made private (Mauro #v4l)
 - Added COMPILE_TEST to rcar_drif in Kconfig (Hans)

v5 -> v6:
 - Addressed Sakari's comments & rebased to his branch.
 - Used fwnode_ instead of of_ apis whereever applicable.

v4 -> v5:
 - Minor documentation changes. Refer individual patches.

v3 -> v4:
 - Added ACKs
rcar_drif:
 - Incorporated a number of review comments from Laurent on DRIF driver.
 - Addressed comments from Rob and Laurent on bindings.
max2175:
 - Minor changes addressing Hans and Laurent's comments

v2 -> v3:
rcar_drif:
 - Reduced DRIF DT properties to expose tested I2S mode only (Hans - discussion 
on #v4l)
 - Fixed error path clean up of ctrl_hdl on rcar_drif

v1 -> v2:
 - SDR formats renamed as "planar" instead of sliced (Hans)
 - Documentation formatting correction (Laurent)

 rcar_drif:
 - DT model using "bonding" property
 - Addressed Laurent's coments on bindings - DT optional parameters rename & 
rework
 - Addressed Han's comments on driver
 - Addressed Geert's comments on DT

 max2175:
 - Avoided scaling using method proposed by Antti. Thanks
 - Bindings is a separate patch (Rob)
 - Addressed Rob's comment on bindings
 - Added Custom controls documentation (Laurent)
