* drm/msm: Separate locking of buffer resources from struct_mutexSushmita Susheelendra2017-06-171-2/+0
| | | | | | | | | | | | | | Buffer object specific resources like pages, domains, sg list need not be protected with struct_mutex. They can be protected with a buffer object level lock. This simplifies locking and makes it easier to avoid potential recursive locking scenarios for SVM involving mmap_sem and struct_mutex. This also removes unnecessary serialization when creating buffer objects, and also between buffer object creation and GPU command submission.

* | drm: convert drivers to use of_graph_get_remote_nodeRob Herring2017-04-061-27/+1
|/ | | | | | | | | | | | | | | | | | | | | Convert drivers to use the new of_graph_get_remote_node() helper instead of parsing the endpoint node and then getting the remote device node. Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages. Plus the kernel is not a DT validator.

* drm/msm: Construct only one encoder for DSIArchit Taneja2017-02-061-16/+12
| | | | | | | | | | | | | | We currently create 2 encoders for DSI interfaces, one for command mode and other for video mode operation. This isn't needed as we can't really use both the encoders at the same time. It also makes connecting bridges harder. Switch to creating a single encoder. For now, we assume that the encoder is configured only in video mode. Later, the same encoder would be usable in both modes.

| | | | | | | | | | | | | | | | The LVDS port is the first in the list of the output ports in MDP4. The driver assumed that if the port and its corresponding endpoint is defined, then there should be a panel node too. This isn't necessary since boards may not really use a LVDS panel. Don't fail if there isn't a panel node available. While we're at it, use of_graph_get_endpoint_by_regs instead of of_graph_get_next_endpoint to make it more explicit that the LVDS output is at port 0.

* drm/msm: Call pm_runtime_enable/disable for newly created devicesArchit Taneja2016-07-161-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm/msm: Get irq number within kms driver itselfArchit Taneja2016-07-161-1/+10
| | | | | | | | | | | | | | | | | | | | | | 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>
* drm/msm/mdp4: Clean up some MDP4 clocksArchit Taneja2016-07-161-1/+1
| | | | | | | | | | | | | | | | | 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.

Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should be handled in the DSI driver. Secondly, it shouldn't try to set a fixed voltage for regulators. Voltage constraints should be specified on the regulator via DT and managed by the regulator core. Remove all the DSI PLL regulator related code from the MDP4 driver.

Make the lcdc encoder initialization independent of the availability of the drm panel. We only check if there is a panel node specified in DT. If it isn't, then we don't initialize the encoder at all. The panel node is passed to the lcdc encoder and lvds connector drivers. The connector driver takes the responsibility to retrieve the drm_panel from the panel node, and update the status on whether the panel is connected or not.

* drm/msm: fix fallout of atomic dpms changesRob Clark2015-02-011-0/+34
| | | | | | | | | | | | | | | | | | | | | As a result of atomic DPMS support, the various prepare/commit hooks get called in a way that msm dislikes. We were expecting prepare/commit to bracket a modeset, which is no longer the case. This was needed to hold various extra clk's (such as interface clks) on while we are touching registers, and in the case of mdp4 holding vblank enabled. The most straightforward way to deal with this, since we already have our own atomic_commit(), is to just handle prepare/commit internally to the driver (with some additional vfuncs for mdp4 vs mdp5), and switch everything over to instead use the new enable/disable hooks. It doesn't really change too much, despite the code motion. What used to be in the encoder/crtc dpms() fxns is split out into enable/disable. We should be able to drop our own enable-state tracking, as the atomic helpers should do this for us. But keeping that for the short term for extra debugging as atomic stablizes.

| | | | | | | | | | | | | | | | | | The hw cursor is relatively adept at triggering underflows, which manifest as a "blue flash" (since blue is configured as the underflow color). Juggle a few things around to tighten up the timing for setting cursor registers in DONE irq. And most importantly, don't ever disable the hw cursor. Instead flip it to a blank/empty cursor. This seems far more reliable, as even simply clearing the cursor-enable bit (with no other updates in previous/ following frames) can in some cases cause underflow. v1: original v2: add missing locking spotted by Micah Cc: Micah Richert <richert@braincorporation.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm: add hdmi support for apq8x74/mdp5Rob Clark2014-01-091-4/+6
| | | | | | | | | | | | | | | | The HDMI block is basically the same between older SoC's with mdp4 display controller, and newer ones with mdp5. So mostly this consists of better abstracting out the different sets of regulators, clks, etc. In particular, for regulators and clks we can split it up by what is needed for hot plug detect to work, and what is needed to light up the display. Also, 8x74 has a new phy.. a very simple one, but split out into a different mmio space. And with mdp5, the irq is shared with mdp, so we don't directly register our own irq handler.

* drm/msm: move irq utils to mdp_kmsRob Clark2014-01-091-6/+10
| | | | | | | We'll want basically the same thing for mdp5, so refactor it out so it can be shared. Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm: mdp4_format -> mdp_formatRob Clark2014-01-091-1/+1
| | | | | | | This can be shared between mdp4 and mdp5. Both use the same set of parameters to describe the format to the hw. Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm: move mdp4 -> mdp/mdp4Rob Clark2014-01-091-0/+391
There are some little bits and pieces that mdp4 and mdp5 can share, so move things around so that we can have both in a common parent directory. Signed-off-by: Rob Clark <robdclark@gmail.com>
