Hi Media, DT maintainers, All,
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-next repo
commit:6d95b3f24881c0fd0f345eca959a2a803a040930
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:
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)
