In other words this driver isn't usable due to lack of other drivers. Even if they'd be in place, this hasn't been tested. What would be the likelihood of it functioning in the end? Would it make sense to first get the other drivers to upstream and then see what's the status of atomisp? The atomisp driver has a number of entries in its TODO file, one of which is making the sensor drivers to use the standard kernel interfaces to work with the main driver (atomisp), so that they could be used with any ISP / bridge driver. Also, the interface the atomisp uses with the sensor drivers as well as how the board specific information from firmware is conveyed to the sensor drivers will change to what the rest of the sensor drivers are using. I think a most straightforward way would be to amend the ACPI tables to include the necessary information. Therefore, applying this patch would not have an effective improvement to the users in form of support for new systems and would make the upcoming interface changes more difficult as there would be one more driver to change (and test). For this reason I'm tempted to postpone applying this patch at least until the other drivers are available. Andy, Alan; any opinion? -- Kind regards, Sakari Ailus sakari.ailus@xxxxxxxxxxxxxxx
