Sakari Ailus 33e17ea2d4 media: dt-bindings: smia: Remove documentation of nokia,nvm-size
The nokia,nvm-size property was used to tell the size of the NVM memory
accessible through the sensor's register interface. However, while the
size isn't directly readable through the sensor's register interface, it
can be detected reading the NVM memory until the selected page is no
longer available.

Thus remove this property.

SMIA/SMIA++ sensor
SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension
of that. These definitions are valid for both types of sensors.
More detailed documentation can be found in
Documentation/devicetree/bindings/media/video-interfaces.txt .
The device node should contain a "port" node which may contain one or more
endpoint nodes, in accordance with video interface bindings defined in
Documentation/devicetree/bindings/media/video-interfaces.txt .
Mandatory properties
--------------------
- compatible: "nokia,smia"
- reg: I2C address (0x10, or an alternative address)
- vana-supply: Analogue voltage supply (VANA), typically 2,8 volts (sensor
dependent).
- clocks: External clock to the sensor
- clock-frequency: Frequency of the external clock to the sensor
- link-frequencies: List of allowed data link frequencies. An array of
64-bit elements.
Optional properties
-------------------
- reset-gpios: XSHUTDOWN GPIO
- flash-leds: See ../video-interfaces.txt
- lens-focus: See ../video-interfaces.txt
- rotation: Integer property; valid values are 0 (sensor mounted upright)
and 180 (sensor mounted upside down). See
../video-interfaces.txt .
Endpoint node mandatory properties
----------------------------------
- data-lanes: <1..n>

clock-frequency = <400000>;

link-frequencies = /bits/ 64 <199200000 210000000 499200000>;
