Hi Kieran,
Thank you for the patch.
On Thursday, 3 May 2018 16:36:17 EEST Kieran Bingham wrote:
The VSP1 devices define their specific capabilities through features marked in their device info structure. Various parts of the code read this info structure to infer if the features are available.
Wrap this into a more readable vsp1_feature(vsp1, f) macro to ensure that usage is consistent throughout the driver.
