2016-07-16drm/msm/mdp5: Update compatible strings for MDSS/MDP5Archit Taneja
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: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16drm/msm/mdp5: Add missing mdp5_enable/disable callsArchit Taneja

2016-07-16drm/msm: Call pm_runtime_enable/disable for newly created devicesArchit Taneja
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.

2016-07-16drm/msm/mdp5: Update the register offsets of MDP5 sub-blocksArchit Taneja
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 <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16drm/msm/mdp5: Use updated MDP5 register namesArchit Taneja
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.

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.

2016-07-16drm/msm/mdp5: Prepare new kms_init funcsArchit Taneja
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.

2016-07-16drm/msm/mdp5: Create a separate MDP5 deviceArchit Taneja
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.

2016-07-16drm/msm/mdp5: Add MDSS top level driverArchit Taneja
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: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16drm/msm: Get irq number within kms driver itselfArchit Taneja
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: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-07-16drm/msm/mdp4: Clean up some MDP4 clocksArchit Taneja
Fix some issues with MDP4 clocks: - mdp4_dtv_encoder tries to get "src_clk", which is a RCG(TV_SRC) in MSM8960 and APQ8064. This isn't something the driver should access or configure. Instead of this, configure the "mdp_clk" (MDP_TV_CLK), a branch clock in MMCC that has the TV_SRC as its parent. Setting rate/enabling the "mdp_clk" will eventually configure "src_clk", which is what we want. - Rename "mdp_clk" to "tv_clk" because that's slightly less confusing. - Rename "mdp_axi_clk" to "bus_clk" because that's what we do elsewhere too.

Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers to the msm platform driver. This will simplify the task of ensuring that the connectors are registered only after the drm_device itself is registered. The connectors' destroy ops are made to use kzalloc instead of devm_kzalloc to ensure that that the connectors can be successfully unregistered when the msm driver module is removed.

Global symbols in the kernel should be prefixed by the name of the subsystem and/or driver to avoid conflicts when all code is built-in.

2015-12-11drm: Pass 'name' to drm_universal_plane_init()Ville Syrjälä
Done with coccinelle for the most part. It choked on msm/mdp/mdp5/mdp5_plane.c like so: "BAD:!!!!! enum drm_plane_type type;" No idea how to deal with that, so I just fixed that up by hand. Also it thinks '...' is part of the semantic patch, so I put an 'int DOTDOTDOT' placeholder in its place and got rid of it with sed afterwards. I didn't convert drm_plane_init() since passing the varargs through would mean either cpp macros or va_list, and I figured we don't care about these legacy functions enough to warrant the extra pain. @@ typedef uint32_t; identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ) { ... } @@ identifier dev, plane, possible_crtcs, funcs, formats, format_count, type; @@ int drm_universal_plane_init(struct drm_device *dev, struct drm_plane *plane, unsigned long possible_crtcs, const struct drm_plane_funcs *funcs, const uint32_t *formats, unsigned int format_count, enum drm_plane_type type + ,const char *name, int DOTDOTDOT ); @@ expression E1, E2, E3, E4, E5, E6, E7; @@ drm_universal_plane_init(E1, E2, E3, E4, E5, E6, E7 + ,NULL ) v2: Split crtc and plane changes apart Pass NUL for no-name instead of "" Leave drm_plane_init() alone v3: Add ', or NULL...' to @name kernel doc (Jani) Annotate the function with __printf() attribute (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1449670795-2853-1-git-send-email-ville.syrjala@linux.intel.com

2015-10-22drm/msm/mdp5: Basic support for MDP5 v1.7 (MSM8996)Stephane Viau
This change adds the basic MDP5 support for MSM8996. Signed-off-by: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-10-22drm/msm/mdp: Add Software Pixel Extension supportStephane Viau
In order to produce an image, the scalar needs to be fed extra pixels. These top/bottom/left/right values depend on a various of factors, including resolution, scaling type, phase step and initial phase. Pixel Extension are programmed by hardware in most targets - and can be overwritten by software. For some targets (e.g.: msm8996), software *must* program those registers. In order to ease this computation, let's always use bilinear filters, which are easier to program from kernel. Eventually, all of these values will come down from user space for better quality.

2015-10-22drm/msm/mdp5: Use the newly introduced enum mdp_component_typeStephane Viau
When calculating phase steps, let's use the same enum mdp_component_type in order to ease the readability; 0/1 indexes are a bit confusing and we now have explicit values to index this type of arrays. Signed-off-by: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-10-22drm/msm/mdp5: Avoid printing error messages for optional clocksStephane Viau
The current behavior is to try to get optional clocks and print a dev_err message in case of failure. This looks rather confusing and may increase with the amount of optional clocks. We may need a cleaner way to handle per-device clocks but in the meantime, let's reduce the amount of dev_err messages during the probe.

2015-10-22drm/msm: Fix IOMMU clean up path in case msm_iommu_new() failsStephane Viau
msm_iommu_new() can fail and this change makes sure that we detect the failure and free the allocated domain before going any further. Signed-off-by: Stephane Viau <sviau@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
