* gpu: nvgpu: unify nvgpu and pci probeDeepak Nibade2016-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have completely different versions of probe for nvgpu and pci device Extract out common steps into nvgpu_probe() function and separate it out in new file nvgpu_common.c Divide task of nvgpu_probe() into further smaller functions Do platform specific things (like irq handling, memresource management, power management) only in individual probes and then call nvgpu_probe() to complete the common initialization Move all debugfs initialization to common gk20a_debug_init() This also helps to bringup all debug nodes to pci device Pass debugfs_symlink name as a parameter to gk20a_debug_init() This allows us to set separate debugfs symlink for nvgpu and pci device In case of railgating, cde and ce debugfs, check if platform supports them or not Copy vidmem_is_vidmem from platform to mm structure and set it to true for pci device Return from gk20a_scale_init() if we don't have either of governor or qos_notifier Fix gk20a_alloc_debugfs_init() and gk20a_secure_page_alloc() to receive device pointer instead of platform_device Export gk20a_railgating_debugfs_init() so that we can call it from gk20a_debug_init() Jira DNVGPU-56 Jira DNVGPU-58 Change-Id: I3cc048082b0a1e57415a9fb8bfb9eec0f0a280cd Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1204207 (cherry picked from commit add6bb0a3d5bd98131bbe6f62d4358d4d722b0fe) Reviewed-on: http://git-master/r/1204462 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
