2019-06-20drm/msm/mdp5: Use the interconnect APIGeorgi Djakov1-0/+38
The interconnect API provides an interface for consumer drivers to express their bandwidth needs in the SoC. This data is aggregated and the on-chip interconnect hardware is configured to the most appropriate power/performance profile. Use the API to configure the interconnects and request bandwidth between DDR and the display hardware (MDP port(s) and rotator downscaler). v2: update the path names to be consistent with dpu, handle the NULL path case, updated commit msg from Georgi. v3: split out icc setup into it's own function, and rework logic slightly so no interconnect paths is not fatal.

2019-06-20drm/msm/dpu: add icc voting in dpu_mdss_initAbhinav Kumar1-4/+14
dpu_mdss_destroy() can get called not just from msm_drm_uninit() but also from msm_drm_bind() in case of any failures. dpu_mdss_destroy() removes the icc voting by calling icc_put. This could accidentally remove the voting done by pm_runtime_enable. To make the voting balanced add a minimum vote in dpu_mdss_init() to avoid any unclocked access. This change depends on the following patch which introduces interconnect binding to MDSS driver: https://patchwork.codeaurora.org/patch/708155/ Signed-off-by: Abhinav Kumar <abhinavk@codeaurora.org> Reviewed-by: Sean Paul <sean@poorly.run> Signed-off-by: Rob Clark <robdclark@chromium.org>
2019-06-20drm/msm/dpu: Integrate interconnect API in MDSSJayant Shekhar1-4/+45
The interconnect framework is designed to provide a standard kernel interface to control the settings of the interconnects on a SoC. The interconnect API uses a consumer/provider-based model, where the providers are the interconnect buses and the consumers could be various drivers. MDSS is one of the interconnect consumers which uses the interconnect APIs to get the path between endpoints and set its bandwidth requirement for the given interconnected path. Changes in v2: - Remove error log and unnecessary check (Jordan Crouse) Changes in v3: - Code clean involving variable name change, removal of extra paranthesis and variables (Matthias Kaehlcke) Changes in v4: - Add comments, spacings, tabs, proper port name and icc macro (Georgi Djakov) Changes in v5: - Commit text and parenthesis alignment (Georgi Djakov) Changes in v6: - Change to new icc_set API's (Doug Anderson) Changes in v7: - Fixed a typo Changes in v8: - Handle the of_icc_get() returning NULL case. In practice icc_set_bw() will gracefully handle the case of a NULL path, but it's probably best for clarity to keep num_paths=0 in this case.

But during unbind, the pm_suspend functions are called blindly resulting in a bit of a when the hardware wasn't already active (or booted, in the case of the GMU).

2019-05-24drm/msm/a6xx: Remove devm calls from gmu driverSean Paul1-11/+22
The gmu driver is initialized and cleaned up with calls from the gpu driver. As such, the platform device stays valid after a6xx_gmu_remove is called and the device managed resources are not freed. In the case of gpu probe failures or unbind, these resources will remain managed. If the gpu bind is run again (eg: if there's a probe defer somewhere in msm), these resources will be initialized again for the same device, creating multiple references. In the case of irqs, this causes failures since the irqs are not shared (nor should they be). This patch removes all devm_* calls and manually cleans things up in gmu_remove.

2019-05-24drm/msm/a6xx: Avoid freeing gmu resources multiple timesSean Paul2-5/+10
The driver checks for gmu->mmio as a sign that the device has been initialized, however there are failures in probe below the mmio init. If one of those is hit, mmio will be non-null but freed. In that case, a6xx_gmu_probe will return an error to a6xx_gpu_init which will in turn call a6xx_gmu_remove which checks gmu->mmio and tries to free resources for a second time. This causes a great boom. Fix this by adding an initialized member to gmu which is set on successful probe and cleared on removal.
