* gpu: nvgpu: pmgr: fix MISRA Rule 10.4 ViolationsSai Nikhil2018-09-27
| | | | | | | | | | | | | | | | | | | | | | | MISRA Rule 10.4 only allows the usage of arithmetic operations on operands of the same essential type category. Adding "U" at the end of the integer literals to have same type of operands when an arithmetic operation is performed. This fixes violation where an arithmetic operation is performed on signed and unsigned int types.

| | | | | | | | | | | | | | | This is a big cleanup of return types across a number of modules in the nvgpu driver. Many functions were returning u32 but using negative return codes.

* gpu: nvgpu: De-linuxify pmgr codeAlex Waterman2018-04-05
| | | | | | | | | | | | | | | | | | | | The pmgr code is in theory common code. However there were uses of Linux stuff within this code. This patch cleans that up by deleting the unnecessary os_linux.h includes, usage of kfree() and adds several platform fields to the gk20a struct. The platform data is copied to the gk20a struct in the platform initialization code so that this common code can access said data without requiring any knowledge of the OS platform data.
