[libcamera-devel] [PATCH 10/10] android: camera_device: Handle LENS_SHADING_MAP_MODES

[Jacopo Mondi]

Register the ANDROID_STATISTICS_INFO_AVAILABLE_LENS_SHADING_MAP_MODES
static metadata property inspecting the values retuned by the pipeline
handler through the properties::draft::AvailableLensShadingMapModes
libcamera property.

Reserve in static metadata pack enough space to support all the 2
available lens shading map modes Android defines.
