Some of the serial interfaces are exposed on the camera daughter board.
The camera daughter board can be connected to the carrier board
by means of expansion connectors 1, 2 and 3. The carrier board may host
an RZ/G1M or an RZ/G1N based SoM.
While adding support for the serial interfaces on the camera daughter
board we faced the dilemma of how to properly describe all of the
possible HW configurations and how to maximize code reuse.
The best option would be to use device tree overlays, however there is
still some work to be done on that front before actually using them,
therefore for the time being we decided to provide .dtsi files to
describe the carrier board and the camera daughter board, and provide
.dts files to describe the HW configurations we need to support.
Best regards,

Since the same carrier board may host RZ/G1M and RZ/G1N based
Systems on Module, the DT architecture for iwg20d-q7 needs
better decoupling. This patch provides:
* iwg20d-q7-common.dtsi - its purpose is to define the carrier
board definitions, and its content is basically the same
as the previous version of r8a7743-iwg20d-q7.dts, only it
has no reference to the SoM .dtsi, and that's why the
filename doesn't mention the SoC name any more.
* r8a7743-iwg20d-q7.dts - its new purpose is to put together
the SoM .dtsi (r8a7743-iwg20m.dtsi) and the carrier board
.dtsi defined by this very patch, along with "model" and
"compatible" properties.
The final DT architecture to describe the board is now:
r8a7743-iwg20d-q7.dts # Carrier Board + SoM
├── r8a7743-iwg20m.dtsi # SoM
│ └── r8a7743.dtsi # SoC
└── iwg20d-q7-common.dtsi # Carrier Board
and maximizes the reuse of the definitions for the carrier board
and for the SoM.

This patch adds a .dtsi that describes the camera daughter board
and a .dts to describe the HW made of iWave's RZ/G1M SoM, iWave's
RZ/G1M/G1N Qseven carrier board, and the camera daughter board.
The camera daughter board .dtsi adds support for ttySC[14].

Because it matches the configuration iWave had in their official release based on
kernel 3.10. We decided to keep the same numbering scheme as a precaution to
avoid breaking existing code.

Some of the serial interfaces are exposed on the camera daughter board.
The camera daughter board can be connected to the carrier board
by means of expansion connectors 1, 2 and 3. The carrier board may host
an RZ/G1M or an RZ/G1N based SoM.
While adding support for the serial interfaces on the camera daughter
board we faced the dilemma of how to properly describe all of the
possible HW configurations and how to maximize code reuse.
The best option would be to use device tree overlays, however there is
still some work to be done on that front before actually using them,
therefore for the time being we decided to provide .dtsi files to
describe the carrier board and the camera daughter board, and provide
.dts files to describe the HW configurations we need to support.

Since the same carrier board may host RZ/G1M and RZ/G1N based
Systems on Module, the DT architecture for iwg20d-q7 needs
better decoupling. This patch provides:
* iwg20d-q7-common.dtsi - its purpose is to define the carrier
board definitions, and its content is basically the same
as the previous version of r8a7743-iwg20d-q7.dts, only it
has no reference to the SoM .dtsi, and that's why the
filename doesn't mention the SoC name any more.
* r8a7743-iwg20d-q7.dts - its new purpose is to put together
the SoM .dtsi (r8a7743-iwg20m.dtsi) and the carrier board
.dtsi defined by this very patch, along with "model" and
"compatible" properties.
The final DT architecture to describe the board is now:
r8a7743-iwg20d-q7.dts # Carrier Board + SoM
├── r8a7743-iwg20m.dtsi # SoM
│ └── r8a7743.dtsi # SoC
└── iwg20d-q7-common.dtsi # Carrier Board
and maximizes the reuse of the definitions for the carrier board
and for the SoM.

* [PATCH v2 1/2] ARM: dts: iwg20d-q7: Rework DT architecture
@ 2017-10-06 17:59 ` Fabrizio Castro
0 siblings, 0 replies; 26+ messages in thread
From: Fabrizio Castro @ 2017-10-06 17:59 UTC (permalink / raw)
To: linux-arm-kernel
Since the same carrier board may host RZ/G1M and RZ/G1N based
Systems on Module, the DT architecture for iwg20d-q7 needs
better decoupling. This patch provides:
* iwg20d-q7-common.dtsi - its purpose is to define the carrier
board definitions, and its content is basically the same
as the previous version of r8a7743-iwg20d-q7.dts, only it
has no reference to the SoM .dtsi, and that's why the
filename doesn't mention the SoC name any more.
* r8a7743-iwg20d-q7.dts - its new purpose is to put together
the SoM .dtsi (r8a7743-iwg20m.dtsi) and the carrier board
.dtsi defined by this very patch, along with "model" and
"compatible" properties.
The final DT architecture to describe the board is now:
r8a7743-iwg20d-q7.dts # Carrier Board + SoM
??? r8a7743-iwg20m.dtsi # SoM
??? ??? r8a7743.dtsi # SoC
??? iwg20d-q7-common.dtsi # Carrier Board
and maximizes the reuse of the definitions for the carrier board
and for the SoM.

This patch adds a .dtsi that describes the camera daughter board
and a .dts to describe the HW made of iWave's RZ/G1M SoM, iWave's
RZ/G1M/G1N Qseven carrier board, and the camera daughter board.
The camera daughter board .dtsi adds support for ttySC[14].

This patch adds a .dtsi that describes the camera daughter board
and a .dts to describe the HW made of iWave's RZ/G1M SoM, iWave's
RZ/G1M/G1N Qseven carrier board, and the camera daughter board.
The camera daughter board .dtsi adds support for ttySC[14].
