By default, if using $debugfs/.../rd to log cmdstream, only the cmdstream buffers themselves are logged. But in some cases we want to capture other buffers in the submit (to see VBO's or shaders). So add a mod-param knob to control this. Signed-off-by: -

The MDP4/5 DT node now contains a list of ports that describe how it connects to external encoder interfaces like DSI and HDMI. These follow the standard of_graph bindings, and allow us to get rid of the 'connectors' phandle that contained a list of all the external encoders connected to MDP. Acked-by:

The DSI host and PHY driver currently expects the DT bindings to provide custom properties "qcom,dsi-host-index" and "qcom,dsi-phy-index" so that the driver can identify which DSI instance it is. The binding isn't acceptable, but the driver still needs to figure out what its instance id. This is now done by storing the mmio starting addresses for each DSI instance in every SoC version in the driver. The driver then identifies the index number by trying to match the stored address with comparing the resource start address we get from DT. We don't have compatible strings for DSI PHY on each SoC, but only the DSI PHY type. We only support one SoC version for each PHY type, so we get away doing the same thing above for the PHY driver. We can revisit this when we support two SoCs with the same DSI PHY. Signed-off-by:

Introduce new compatible strings for the top level MDSS wrapper device, and the MDP5 device. Previously, the "qcom,mdp5" and "qcom,mdss_mdp" compatible strings were used to match the top level platform_device (which was also tied to the top level drm_device struct). Now, these strings are used to match the MDP5 platform device. Use "qcom,mdss" as the compatible string for top level MDSS device. This is now used to match the top level platform_device (which is tied to the drm_device struct). Signed-off-by:

The driver currently identifies the GPU components it needs by parsing a phandle list from the 'gpus' DT property. This isn't the right binding to go with. So, for now, just search all device nodes and find the gpu node we need by parsing a list of compatible strings. Once we know how to link the kms and gpu drivers, we'll drop this method and use the correct binding. Signed-off-by:

For MDP5 based platforms, the master device isn't the MDP5 platform device, but the top level MDSS device, which is a parent to MDP5 and interface (DSI, HDMI, eDP etc) devices. In order to add components on MDP5 platforms, we first need to populate the MDSS children, locate the MDP5 child, and then parse its ports to get the display interfaces. Signed-off-by:

The kms driver currently identifies all the mdss components it needs by parsing a phandle list from the 'connectors' DT property. Instead of this, describe a list of ports that the MDP hardware provides to the external world. These ports are linked to external encoder interfaces such as DSI, HDMI. These are also the subcomponent devices that we need add. This description of ports complies with the generic graph bindings. The LVDS port is a special case since it is a part of MDP4 itself, and its output connects directly to the LVDS panel. In this case, we don't try to add it as a component. Signed-off-by:

Since runtime PM isn't implemented yet, we need to call mdp5_enable/disable in a few more places. These would later be replaced by runtime PM get/put calls. Signed-off-by:

Archit Taneja authored
With the new device hierarchy for MDP5, we need to enable runtime PM for both the toplevel MDSS device and the MDP5 device itself. Enable runtime PM for the new devices. Since MDP4 and MDP5 now have different places where runtime PM is enabled, remove the previous pm_runtime_enable/disable calls, and squash them in the respective kms drivers. The new device hierarchy (as expressed in the DT bindings) has the GDSC tied only to the MDSS wrapper device. This GDSC needs to be enabled for accessing any register in the MDSS sub-blocks. Once every driver is runtime adapted, the GDSC will be enabled when any sub-block device calls runtime_get because of the parent-child relationship with MDSS. Until then, we call pm_runtime_get_sync() once for the MDSS device to ensure the GDSC is never disabled. This will be removed once all the drivers are runtime PM adapted. The error handling paths become a bit tricky when we call these runtime PM funcs. There doesn't seem to be any helper that checks if runtime PM is enabled already. Add bool variables in mdp4_kms/mdp5_kms structs to check if the driver had managed to call pm_runtime_enable before bailing out. Signed-off-by:

The MDP5 sub-block register offsets are relative to the top level MDSS register address. Now that we have the start of MDP5 register address space, provide the offsets relative to that. This involves subtracting the offsets with 0x1000 or 0x100 depending on the MDP5 version. Signed-off-by:

Archit Taneja authored
Since MDSS registers were stuffed within the the MDP5 register space, we had an __offset_MDP() macro to identify the offset between the start of MDSS and MDP5 address spaces. This offset macro expected a MDP index argument, which didn't make much sense since we don't have multiple MDPs. The offset is no longer needed now that we have devices for the 2 different register address spaces. Also, remove the "REG_MDP5_MDP_" prefix to "REG_MDP5_". Update the generated headers in mdp5.xml.h We generally update headers as a separate patch, but we need to do these together to prevent breaking build. Signed-off-by:

With the new kms_init/destroy funcs in place for MDP5, we can get rid of the old kms funcs. Some members of the mdp5_kms struct also become redundant, so we remove those too. Signed-off-by:

Call msm_mdss_init in msm_drv to set up top level registers/irq line. Start using the new kms_init2/destroy2 funcs to inititalize MDP5 KMS. With the MDSS interrupt and irqdomain set up, the old MDP5 irq code can be dropped. The mdp5_hw_init kms func now uses the platform device tied to MDP5 instead of the one tied to the drm_device/MDSS.

With MDP5 as a new device, we need to do less for MDP when initializing modeset after all the components are bound. Create mdp5_kms_init2/destroy2 funcs that inits modeset. These will eventually replace the older kms_init/destroy funcs. In the new kms_init2, the platform_device used is the one corresponding to the new MDP5 platform_device. The new change here is that the irq is now retrieved using irq_of_parse_and_map(), since MDP5 is a child interrupt of the MDSS interrupt controller. Signed-off-by:

In order to have a tree-like device hierarchy between MDSS and its sub-blocks (MDP5, DSI, HDMI, eDP etc), we need to create a separate device/driver for MDP5. Currently, MDP5 and MDSS are squashed together are are tied to the top level platform_device, which is also the one used to create drm_device. The mdp5_kms_init code is split into two parts. The part where device resources are allocated are associated with the MDP5 driver's probe, the rest is executed later when we initialize modeset. With this change, unlike MDP4, the MDP5 platform_device isn't tied to the top level drm_device anymore. The top level drm_device is now associated with a platform device that corresponds to MDSS wrapper hardware. Create mdp5_init/destroy funcs that will be used by the MDP5 driver probe/remove. Use the HW_VERSION register in the MDP5 register address space. Both the MDSS and MDP VERSION registers give out identical version info. The older mdp5_kms_init code is left as is for now, this would be removed later when we have all the pieces to support the new device hierarchy. Signed-off-by:

SoCs that contain MDP5 have a top level wrapper called MDSS that manages clocks, power and irq for the sub-blocks within it. Currently, the MDSS portions are stuffed into the MDP5 driver. This makes it hard to represent the DT bindings in the correct way. We create a top level MDSS helper that handles these parts. This is essentially moving out some of the mdp5_kms irq code and MDSS register space and keeping it as a separate entity. We haven't given any clocks to the top level MDSS yet, but a AHB clock would be added in the future to access registers. One thing to note is that the resources allocated by this helper are tied to the top level platform_device (the one that allocates the drm_device struct too). This device would be the parent to MDSS sub-blocks like MDP5, DSI, eDP etc. Signed-off-by:

The driver gets the irq number using platform_get_irq on the main kms platform device. This works fine since both MDP4 and MDP5 currently have a flat device hierarchy. The platform device tied with the drm_device points to the MDP DT node in both cases. This won't work when MDP5 supports a tree-like hierarchy. In this case, the platform device tied to the top level drm_device is the MDSS DT node, and the irq we need for KMS is the one generated by MDP5, not MDSS. Get the irq number from the MDP4/5 kms driver itself. Each driver can later provide the irq number based on what device hierarchy it uses. While we're at it, call drm_irq_install only when we have a valid KMS driver. Signed-off-by:

The PLL in the DSI PHY block generates 2 clock outputs (Byte and Pixel clocks) that are fed into the Multimedia Clock Controller (MMCC). The MMCC uses these as source clocks for some of its RCGs to generate clocks that finally feed to the DSI host controller. Use the assigned clocks DT bindings to set up the MMCC RCGs that feed to the DSI host. Use the DSI PHY provided clocks to set up the parents of these assigned clocks. Acked-by:

The "qcom,data-lane-map" binding mentioned in the document is changed to the more generic "data-lanes" property specified in: Documentation/devicetree/bindings/media/video-interfaces.txt The previous binding expressed physical to logical data lane mappings, the standard "data-lanes" binding uses logical to physical data lane mappings. Update the docs to reflect this change. The example had the property incorrectly named as "lanes", update this too. The MSM DSI DT bindings aren't used anywhere at the moment, so it's okay to update this property. Acked-by:

A more standard DT binding describing data lanes already exists here: Documentation/devicetree/bindings/media/video-interfaces.txt Use this binding instead of "qcom,data-lane-map". One difference in the standard binding w.r.t to the existing binding is that it provides a logical to physical mapping instead of the other way round. Tweak the code to translate the data the way we want it. The MSM DSI DT bindings aren't used anywhere at the moment, so it's okay to update this property. Signed-off-by:
