2015-10-02drm/amdgpu: add pm sysfs files lateAlex Deucher1-4/+6
They were added relatively early in the driver init process which meant that in some cases the driver was not finished initializing before external tools tried to use them which could result in a crash depending on the timing.

2015-06-10drm/amdgpu/cz: don't call smu_init on resumeAlex Deucher1-7/+8
smu_init allocates buffers and initializes them. It does not touch the hw. There is no need to do it again on resume. It should really be part of sw_init (and smu_fini should be part of sw_fini), but we need the firmware sizes from the other IPs for firmware loading so we have to wait until sw init is done for all other IPs.
