Krzysztof Kozlowski Nov. 18, 2020, 8:27 p.m. UTC 
Add bindings for the IMX258 camera sensor.  The bindings, just like the
driver, are quite limited, e.g. do not support regulator supplies.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
Reviewed-by: Rob Herring <robh@kernel.org>

---

Changes since v4:
1. Add clock-lanes,
2. Add Rob's review,
3. Add one more example and extend existing one,
4. Add common clock properties (assigned-*).

Changes since v3:
1. Document also two lane setup.

Changes since v2:
1. Remove clock-frequency, add reset GPIOs, add supplies.
2. Use additionalProperties.

Changes since v1:
1. None

This is redundant. Please remove, same for the examples. Can be a separate
patch, too.

With this change the set seems good to me.

OK, I'll remove it and send a v7.

Before I remove too much - you mean "clock-lanes" is redundant or entire
set of properties in "port" node?

+description: |-
+  IMX258 is a diagonal 5.867mm (Type 1/3.06) 13 Mega-pixel CMOS active pixel
+  type stacked image sensor with a square pixel array of size 4208 x 3120. It
+  is programmable through I2C interface.  Image data is sent through MIPI
+  CSI-2.
