TSP build fails

[ballestrerod]

hi, you're the only one that answers about rockchip devel. I'm facing a build problem related to RK3328 TSP. seems that devel is incomplete or something is incomplete. build fails because of missing rk_tsp_api.h file.

is TSP support broken for my chip? Can you help me? I really need this interface for a project I'm working on and I'm a little bit worried about it.

thank you davide

sorry, i mostly working on userspace...

that driver seems to be broken from the beginning, and the author is no longer working at rockchip now :(

if you are a rockchip official customer, maybe try to ask it in rockchip redmine issue system, maybe someone can try to port the driver again
