2016-02-29drm/msm/hdmi: Clean up connector gpio usageArchit Taneja3-100/+67
Make gpio allocation and usage iterative by parsing the gpios on a given platform from a list. This gives us flexibility over what all gpios exist for a platform, whether they are input or output, and what value they should be set to. In particular, this will make HDMI on 8x96 platforms easier to integrate with the driver, as it doesn't have a HPD gpio input to them. Also, it cleans things up a bit. We still use the legacy gpio api here, as we might need to backport this driver to downstream kernels.

2016-02-27drm/amdgpu: Return -EPROBE_DEFER when amdkfd not loadedOded Gabbay3-39/+30
amdgpu must load only after amdkfd's loading has been completed. If that is not enforced, then amdgpu's call into amdkfd's functions will cause a kernel BUG. When amdgpu and amdkfd are built as kernel modules, that rule is enforced by the kernel's modules loading mechanism. When amdgpu and amdkfd are built inside the kernel image, that rule is enforced by ordering in the drm Makefile (amdkfd before amdgpu). Instead of using drm Makefile ordering, we can now use deferred loading as amdkfd now returns -EPROBE_DEFER in kgd2kfd_init() when it is not yet loaded. This patch defers amdgpu loading by propagating -EPROBE_DEFER to the kernel's drivers loading infrastructure. That will put amdgpu into the pending drivers list (see description in dd.c). Once amdkfd is loaded, a call to kgd2kfd_init() will return successfully and amdgpu will be able to load.

2016-02-27drm/amdkfd: Track when module's init is completeOded Gabbay4-8/+17
Current dependencies between amdkfd and radeon/amdgpu force the loading of amdkfd _before_ radeon and/or amdgpu are loaded. When all these kernel drivers are built as modules, this ordering is enforced by the kernel built-in mechanism of loading dependent modules. However, there is no such mechanism in case where all these drivers are compiled inside the kernel image (not as modules). The current way to enforce loading of amdkfd before radeon/amdgpu, is to put amdkfd before radeon/amdgpu in the drm Makefile, but that method is way too fragile. In addition, there is no kernel mechanism to check whether a kernel driver that is built inside the kernel image, has already been loaded. To solve this, this patch adds to kfd_module.c a new static variable, amdkfd_init_completed, that is set to 1 only when amdkfd's module initialization function has been completed (successfully). kgd2kfd_init(), which is the initialization function of the kgd-->kfd interface, and which is the first function in amdkfd called by radeon/amdgpu, will return successfully only if amdkfd_init_completed is equal 1. If amdkfd_init_completed is not equal to 1, kgd2kfd_init() will return -EPROBE_DEFER to signal radeon/amdgpu they need to defer their loading until amdkfd is loaded.
