Looks like we never opened an issue for this. Cameras are:

• NEC CE147 (5MP rear camera)
• Samsung S5KA3DFX (comment in vendor kernel source code says 1/4" 2.0Mp CMOS image sensor but the driver only supports 0.3MP)

Is connected to the FIMC; based on pawitp/android_kernel_samsung_aries@359bccf S5K is connected to FIMC0; but Android userspace opens both FIMC0 and FIMC2 for both cameras regardless.
