* gpu: nvgpu: Use timeout retry API in xveKonsta Holtta2017-06-19
| | | | | | | | | | | | | | | Get rid of manual timeout tracking with jiffies in xve_gp106.c by using the timeout API instead.

* gpu: nvgpu: remove duplicate \n from log messagesStephen Warren2017-05-26
| | | | | | | | | | | | | | | nvgpu_log/info/warn/err() internally add a \n to the end of the message. Hence, callers should not include a \n at the end of the message. Doing so results in duplicate \n being printed, which ends up creating empty log messages. Remove the duplicate \n from all err/warn messages.

* gpu: nvgpu: Scrub gk20a_platform dependenciesTerje Bergstrom2017-05-18
| | | | | | | | | | | | | | Remove gk20a_platform dependencies from gk20a.h. This makes gk20a_platform a Linux platform specific data structure. Add #include for platform_gk20a.h in the source files that still depend on Linux.

* gpu: nvgpu: Use correct register for ROM controlTerje Bergstrom2017-04-28
| | | | | | | | | | | | | | We access ROM control register with xve_writel, but we also add the base register address. This leads to adding the base address twice, and the access goes to wrong register.

* gpu: nvgpu: Put debugfs dependencies inside #ifdefTerje Bergstrom2017-04-24
| | | | | | | | | | | | | | | | | | | Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This includes some functions in allocators that were used only for debugging. Remove include of linux/debugfs.h on files that do not deal with debugfs. linux/debugfs.h implicitly included linux/fs.h, which we relied on. Add explicit include of linux/fs.h for all files where this is the case.
