I looked at it, but that doesn't actually tell me the touchscreen interface. It just tells me the bits they're currently using. If Apple had open sourced their driver it wouldn't have made a difference, as whatever they're doing differently wouldn't have been in it until now. In order for me to make a fully compatible touchscreen, I need the datasheet and programming manual for the touchscreen controller.
As much as open source is a thing for software, it is not for hardware and especially silicon.

This is not a full hardware specification, it just tells how the hardware should behave up until the driver was released. Modern open source hardware is still far in the future.
- axoltl 9y agoOpen source hardware's still far in the future, and I'm actively worried about open silicon. The RISC-V foundation is making steps in the right direction, but it'll be a long time coming before I have a document that isn't under several layers of NDA telling me how to configure the memory controller on the latest Snapdragon.
