2019-11-05drm/msm/dsi: Add configuration for 8x76AngeloGioacchino Del Regno2-0/+23
MSM8976, MSM8976 and APQ variants have DSI version 3:10040002 (DSI 6G V1.4.2), featuring two DSIs. They need three clocks (mdp_core, iface, bus), one GDSC and two vregs, VDDA at 1.2V and VDDIO at 1.8V.

2019-10-24drm/msm/dsi: Implement qcom, dsi-phy-regulator-ldo-mode for 28nm PHYStephan Gerhold1-8/+34
The DSI PHY regulator supports two regulator modes: LDO and DCDC. This mode can be selected using the "qcom,dsi-phy-regulator-ldo-mode" device tree property. However, at the moment only the 20nm PHY driver actually implements that option. Add a check in the 28nm PHY driver to program the registers correctly for LDO mode.

2019-10-11drm/msm/dsi: Implement reset correctlyJeffrey Hugo1-2/+4
On msm8998, vblank timeouts are observed because the DSI controller is not reset properly, which ends up stalling the MDP. This is because the reset logic is not correct per the hardware documentation. The documentation states that after asserting reset, software should wait some time (no indication of how long), or poll the status register until it returns 0 before deasserting reset. wmb() is insufficient for this purpose since it just ensures ordering, not timing between writes. Since asserting and deasserting reset occurs on the same register, ordering is already guaranteed by the architecture, making the wmb extraneous. Since we would define a timeout for polling the status register to avoid a possible infinite loop, lets just use a static delay of 20 ms, since 16.666 ms is the time available to process one frame at 60 fps.

2018-12-11drm/msm: Add a name field for gem objectsJordan Crouse1-0/+2
For debugging purposes it is useful to assign descriptions to buffers so that we know what they are used for. Add a field to the buffer object and use that to name the various kernel side allocations which ends up looking like like this in /d/dri/X/gem: flags id ref offset kaddr size madv name 00040000: I 0 ( 1) 00000000 0000000070b79eca 00004096 memptrs vmas: [gpu: 01000000,mapped,inuse=1] 00020000: I 0 ( 1) 00000000 0000000031ed4074 00032768 ring0 Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-12-11drm/msm: Count how many times iova memory is pinnedJordan Crouse1-1/+1
Add a reference count to track how many times a particular chunk of iova memory is pinned (mapped) in the iomu and add msm_gem_unpin_iova to give up references. It is important to note that msm_gem_unpin_iova replaces msm_gem_put_iova because the new implicit behavior that an assigned iova in a given vma is now valid for the life of the buffer and what we are really focusing on is the use of that iova. For now the unmappings are lazy; once the reference counts go to zero they *COULD* be unmapped dynamically but that will require an outside force such as a shrinker or mm_notifiers. For now, we're just focusing on getting the counting right and setting ourselves up to be ready for the future.

2018-12-11drm/msm: Add msm_gem_get_and_pin_iova()Jordan Crouse1-1/+1
Add a new function to get and pin the iova memory in one step (basically renaming the old msm_gem_get_iova function) and switch msm_gem_get_iova() to only allocate an iova but not map it in the IOMMU. This is only currently used by msm_ioctl_gem_info() since all other users of of the iova expect that the memory be immediately available.

2018-10-04drm/msm: dsi: Initialize msm_dsi->id to -1Sean Paul2-1/+4
Currently msm_dsi->id is initialized to 0 during kzalloc. If bind fails for a secondary dsi device before its id can be properly set (such as during dt parsing), the id will point to the primary dsi device, causing its reference to be removed from dsi_manager's global (msm_dsim_glb) array. This patch initializes the id to -1 and checks for negative in the manager cleanup.
