* gpu: nvgpu: remove gk20a_handleDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | Remove static variable gk20a_handle used to store pointer to struct gk20a Use below device tree APIs to get pointer to platform_device and then struct gk20a device_node = of_find_matching_node() platform_device = of_find_device_by_node(device_node) Also, use two versions of do_idle()/do_unidle() APIs - one will receive void (to be used from outside GPU driver) and another will receive platform_device (to be used within GPU driver where it is available) Change-Id: I9f2c7610646c5fbcd3d99a1b03dc0364201272a8 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/496508 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: Ken Adams <kadams@nvidia.com> GVS: Gerrit_Virtual_Submit

* gpu: nvgpu: remove hard coded GPU nameDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | In gk20a_do_idle(), to get pointer to platform_device of gk20a, we use bus_find_device_by_name() and pass "gk20a.0" to it But this hard coding fails on gm20b since GPU device name there is "gpu" Hence to fix this add a static pointer handle "gk20a_handle" to struct gk20a in gk20a.c Now we can access this global pointer inside do_idle() to get gk20a pointer and from that we can get pointer to platform_device Change-Id: I1a65588e34ad36efed0fa587bb365f0ee81e253d Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/486887 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: Fall-back to generic platformArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | | Currently the generic platform is used only if the device tree defines that we have a generic platform available, however, the generic platform is fully compatible with the gk20a we have in tegra. This patch modifies the definitions so that we use generic platform also for tegra - even if if tegra configuration option is not enabled.
