Teaches the software ISP's AGC the IMX896 gain law (gain = 16384/(16384-code), inverted from the vendor driver and round-tripped against all 3009 vendor gain-table entries, max error 0.049%) and adds the sensor properties (1.0um unit cell, test-pattern map). Same shape as the OV13B10 pair; both verified to apply and compile on v0.7.2 after 0001-0004. The extracted-CCM tuning yaml is deliberately NOT packaged yet - the color matrices come from the vendor Chromatix blob and the licensing call is open (see the camera journal).

Subject: [PATCH] libcamera: sensor: Add IMX896 sensor properties
|
|
|
|
Add the Sony IMX896 (Fairphone 6 main camera, 50 MP, 8192x6144) to
|
|
the static properties database: 1.0 um unit cell and the test pattern
|
|
modes exposed by the kernel driver (V4L2 menu indices map 1:1 to
|
|
register 0x0600 values). Removes the "No static properties available
|
|
for 'imx896'" warning.
