Remove static class definition and registration for iGPU and dGPU. Create the class dynamically in gk20a_user_init() and setup the callback function to create devnode name based on GPU type. For now add nvgpu_pci_devnode() callback for dGPU that sets correct dev node path for dGPUs. For iGPU, Android apparently does not honor dev node path set in callback and hence override the device name for iGPU with function nvgpu_devnode(). Destroy the class in gk20a_user_deinit(). This will overall be helpful in adding multiple classes and dev nodes for each GPU instance in MIG mode. Set GPU device pointer as the parent of new devices created with device_create(). This is helpful in getting GPU device name in callback function nvgpu_pci_devnode(). Update functions to not pass class structure and interface names : nvgpu_probe() gk20a_user_init() gk20a_user_deinit() nvgpu_remove() Remove static interface name format like INTERFACE_NAME since it is no longer needed. Update GK20A_NUM_CDEVS to 10 since there are 10 dev nodes per GPU right now.
