add a title:, please, otherwise this will look really odd/wrong in boards' documentation
I guess you want something like "GPIO pins exposed on the Raspberry Pi CSI Camera connector".

| There are 2 variants of the Raspberry Pi CSI camera connector. Either 15pins |
There was a problem hiding this comment.
kind of a nit but since you need to add the title anyway:
15pins --> 15-pin
22pins --> 22-pin
fix everywhere

…ctor Update the RaspberryPi CSI camera connector nexus gpio in order to only expose the list of GPIO pins in order to support both 15-pin and 22-pin connectors as well as 15-pin to 22-pin conversion cables. Signed-off-by: Alain Volmat <alain.volmat@foss.st.com>
Following renaming of the raspberry csi connector nexus, rename all places when csi 22pins is mentioned to only keep csi instead. Signed-off-by: Alain Volmat <alain.volmat@foss.st.com>

Thanks @kartben, I updated the yaml file and used your proposal as title. |

A first nexus has been introduced for the raspberry pi 22pins CSI connector. There are also 15pins CSI connectors as well as also 15pins to 22pins conversion cables.
As far as GPIO are concerned there are only 4 pins importants in those connectors, IO0 / IO1 / I2C_SCL and I2C_SDA.
The other pins are directly connected to CSI PHY for which Zephyr doesn't have much to do.
In order to avoid having to deal with 2 kinds of connectors / nexus and having to figure a way to deal with cases when a conversion cable is being used, simply have the gpio-nexus list only the 4 GPIOs.
The other commits update DTSI and overlay to update the csi-22pins into simply csi.
Follwing this, I will update the PR #91837 and PR #88011 should also be updated.
