We are currently leaking a drm_crtc_commit struct for every atomic commit containing plane state.

2018-10-04drm/msm/a6xx: Add devfreq support for a6xxSharat Masetty
Implement routines to estimate GPU busy time and fetching the current frequency for the polling interval. This is required by the devfreq framework which recommends a frequency change if needed. The driver code then tries to set this new frequency on the GPU by sending an Out Of Band(OOB) request to the GMU.

2018-10-04drm/msm: re-factor devfreq codeSharat Masetty
The devfreq framework requires the drivers to provide busy time estimations. The GPU driver relies on the hardware performance counteres for the busy time estimations, but different hardware revisions have counters which can be sourced from different clocks. So the busy time estimation will be target dependent. Additionally on targets where the clocks are completely controlled by the on chip microcontroller, fetching and setting the current GPU frequency will be different. This patch aims to embrace these differences by re-factoring the devfreq code a bit. Signed-off-by: Sharat Masetty <smasetty@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2018-10-04drm/msm: suspend devfreq on initSharat Masetty
Devfreq turns on and starts recommending power level as soon as it is initialized. The GPU is still not powered on by the time the devfreq init happens and this leads to problems on GPU's where register access is needed to get/set power levels. So we start suspended and only restart devfreq when GPU is powered on. Signed-off-by: Sharat Masetty <smasetty@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

The point of the 'force_dma' parameter for of_dma_configure is to force the device to be set up even if DMA capability is not described by the firmware which is exactly the use case we have for GMU - we need SMMU to get set up but we have no other dma capabilities since memory is managed by the GPU driver. Currently we pass false so of_dma_configure() fails and subsequently GMU and GPU probe does as well.
