[media] atmel-isi: setup the ISI_CFG2 register directly

2015-09-25T20:35:15+00:00

In the function configure_geometry(), we will setup the ISI CFG2 according to the sensor output format. It make no sense to just read back the CFG2 register and just set part of it. So just set up this register directly makes things simpler. Currently only support YUV format from camera sensor.

[media] media: atmel-isi: increase the burst length to improve the performance

2015-03-02T16:27:11+00:00

The burst length could be BEATS_4/8/16. Before this patch, isi use default value BEATS_4. To imporve the performance we could set it to BEATS_16. Otherwise sometime it would cause the ISI overflow error. Reported-by: Bo Shen Signed-off-by: Josh Wu Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

[media] v4l: atmel-isi: Should clear bits before set the hardware register

2013-12-18T08:55:48+00:00

In the ISI driver it reads the config register to get original value, then set the correct FRATE_DIV and YCC_SWAP_MODE directly. This will cause some bits overlap. So we need to clear these bits first, then set correct value. This patch fix it. Signed-off-by: Josh Wu Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab
