[PATCH 0/3]

[Gareth Williams]

This series adds DRM support for the Digital Blocks db9000
LCD controller with RZ/N1 specific changes and updates simple-panel to
include the associated panel. As this has not previously been
documented, also include a yaml file to provide this.

+description: |
+  This is an LCD controller by Digital Blocks available for SoCs. The DB9000
+  controller reads from the framebuffer to display on a single RGB interface.
+  Output may be formatted in RGB or BGR. The driver also supports the PWM
+  logic that is included with the controller.

RE: [PATCH 0/3]

[Gareth Williams]

Hi All,

I noticed some API changes that were not present when I first wrote this driver. 
This will need correcting so I will send out a second version and respond 
to Sam Ravnborg's feedback at the same time. I recommend waiting for that
version before reviewing as this will not function on Linux-next otherwise.

My bot found errors running 'make dt_binding_check' on your patch:

Documentation/devicetree/bindings/display/db9000,du.example.dts:28.35-30.15: Warning (unit_address_vs_reg): /example-0/drm@53004000/port/endpoint@0: node has a unit name, but no reg or ranges property
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/display/db9000,du.example.dt.yaml: drm@53004000: clock-names:0: 'lcd_eclk' was expected

See https://patchwork.ozlabs.org/patch/1277401

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

[PATCH 0/3]

[Antoniu Miclaus]

The ADMV1014 is a silicon germanium (SiGe), wideband,
microwave downconverter optimized for point to point microwave
radio designs operating in the 24 GHz to 44 GHz frequency range.

Datasheet:
https://www.analog.com/media/en/technical-documentation/data-sheets/ADMV1014.pdf

NOTE:
Currently depends on 64-bit architecture since the input
clock that server as Local Oscillator should support values
in the range 24 GHz to 44 GHz.

We might need some scaling implementation in the clock
framework so that u64 types are supported when using 32-bit
architectures.
