Hi all,
I am playing around with some parameters in the previewer on the ISP.
With ioctl VIDIOC_OMAP3ISP_PRV_CFG I am able to write the various
parameters but what I'm missing is a way to read them. For example, I
have no way to adjust only coef2 in 'struct omap3isp_prev_wbal' while
leaving the others unchanged. If I could first read the whole
omap3isp_prev_wbal structure, then I could change just the things I want
to change. This seems like it would be common functionality for such
ioctls. I didn't find any previous discussion related to this.
I could imagine either adding a r/w flag to 'struct
omap3isp_prev_update_config' or adding a new ioctl entirely. I think I
would prefer the r/w flag. Feedback?
I noticed that other ISP subdevs have similar ioctls. Perhaps a similar
thing would be useful there, but right now I'm only looking at the
previewer.
