2018-12-03drm/msm/hdmi: Enable HPD after HDMI IRQ is set upTodor Tomov1-0/+6
SoCs that contain MDP5 have a top level wrapper called MDSS that manages locks, power and irq for the sub-blocks within it. Irq for HDMI is also routed through the MDSS. Shortly after the Hot Plug Detection (HPD) is enabled in HDMI, HDMI interrupts are recieved by the MDSS interrupt handler. However at this moment the HDMI irq is still not mapped to the MDSS irq domain so the HDMI irq handler cannot be called to process the interrupts. This leads to a flood of HDMI interrupts on CPU 0. If we are lucky to have the HDMI initialization running on a different CPU, it will eventually map the HDMI irq to MDSS irq domain, the next HDMI interrupt will be handled by the HDMI irq handler, the interrupt flood will stop and we will recover. If the HDMI initialization is running on CPU 0, then it cannot complete and there is nothing to stop the interrupt flood on CPU 0. The system is stuck. Fix this by moving the HPD enablement after the HDMI irq is mapped to the MDSS irq domain.

2018-10-01drm: Convert to using %pOFn instead of device_node.nameRob Herring1-1/+1
In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier. For drm_modes.c, the full node path is already printed out, so printing just the node name a 2nd time is redundant and can be removed.

2018-06-12treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook1-8/+16
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

2016-09-15drm/msm/hdmi: Clean up HDMI gpio DT bindingsArchit Taneja1-2/+19
Make the following changes in the HDMI gpio bindings: - Use "-gpios" as the suffix for all the gpio names - Move all the gpios to optional, since there are platforms that use none of them. - The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from it. - Remove the HDMI DDC clk/data gpios. They are just leftovers of an old way to configure pinctrl properties. - Add a missing lpm gpio used on some platforms. Make the necessary changes in the driver to incorporate these changes. There hasn't been any upstream DT that uses the HDMI bindings, so it's okay to change and move around these properties.

2016-03-03drm/msm: rename hdmi symbolsArnd Bergmann1-49/+49
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. In this case, function names like 'hdmi_register' or 'hdmi_set_mode' are way too generic for an MSM specific DRM driver, so I'm renaming them all to msm_hdmi_* here. I also rename a lot of the 'static' symbols along with the global names for consistency, even though those are relatively harmless; they might only be slightly confusing when they show up in backtraces.

2016-02-29drm/msm/hdmi: Create a separate HDMI PHY driverArchit Taneja1-0/+2
Create a PHY device that represents the TX PHY and PLL parts of the HDMI block. This makes management of PHY specific resources (regulators and clocks) much easier, and makes the PHY and PLL usable independently. It also simplifies the core HDMI driver, which currently assigns phy ops among many other things. The PHY driver implementation done here is very similar to the PHY driver we already have for DSI. Keep the old hdmi_phy_funcs ops for now. The driver will use these until the HDMI PHY/PLL register offsets aren't considered as separate domains (i.e. their offsets start from 0). The driver doesn't use the common PHY framework for now. This is because it's hard to map our ops with the ops provided by the framework. The bindings used for this is the generic phy bindings. So, this can be adapted to the PHY framework in the future, if possible. Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2016-02-29drm/msm/hdmi: Clean up connector gpio usageArchit Taneja1-7/+24
Make gpio allocation and usage iterative by parsing the gpios on a given platform from a list. This gives us flexibility over what all gpios exist for a platform, whether they are input or output, and what value they should be set to. In particular, this will make HDMI on 8x96 platforms easier to integrate with the driver, as it doesn't have a HPD gpio input to them. Also, it cleans things up a bit. We still use the legacy gpio api here, as we might need to backport this driver to downstream kernels.

2015-01-28drm/bridge: make bridge registration independent of drm flowAjay Kumar1-2/+2
Currently, third party bridge drivers(ptn3460) are dependent on the corresponding encoder driver init, since bridge driver needs a drm_device pointer to finish drm initializations. The encoder driver passes the drm_device pointer to the bridge driver. Because of this dependency, third party drivers like ptn3460 doesn't adhere to the driver model. In this patch, we reframe the bridge registration framework so that bridge initialization is split into 2 steps, and bridge registration happens independent of drm flow: --Step 1: gather all the bridge settings independent of drm and add the bridge onto a global list of bridges. --Step 2: when the encoder driver is probed, call drm_bridge_attach for the corresponding bridge so that the bridge receives drm_device pointer and continues with connector and other drm initializations. The old set of bridge helpers are removed, and a set of new helpers are added to accomplish the 2 step initialization. The bridge devices register themselves onto global list of bridges when they get probed by calling "drm_bridge_add". The parent encoder driver waits till the bridge is available in the lookup table(by calling "of_drm_find_bridge") and then continues with its initialization. The encoder driver should also call "drm_bridge_attach" to pass on the drm_device to the bridge object. drm_bridge_attach inturn calls "bridge->funcs->attach" so that bridge can continue with drm related initializations.

2014-11-21drm/msm/mdp5: use irqdomainsRob Clark1-18/+15
For mdp5, the irqs of hdmi/eDP/dsi0/dsi1 blocks get routed through the mdp block. In order to decouple hdmi/eDP/etc, register an irq domain in mdp5. When hdmi/dsi/etc are used with mdp4, they can directly setup their irqs in their DT nodes as normal. When used with mdp5, instead set the mdp device as the interrupt-parent, as in: mdp: qcom,mdss_mdp@fd900000 { compatible = "qcom,mdss_mdp"; interrupt-controller; #interrupt-cells = <1>; ... }; hdmi: qcom,hdmi_tx@fd922100 { compatible = "qcom,hdmi-tx-8074"; interrupt-parent = <&mdp>; interrupts = <8 0>; /* MDP5_HW_INTR_STATUS.INTR_HDMI */ ... }; There is a slight awkwardness, in that we cannot disable child irqs at the mdp level, they can only be cleared in the child block. So you must not use threaded irq handlers in the child. I'm not sure if there is a better way to deal with that. Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-11-16drm/msm/hdmi: refactor bind/initRob Clark1-38/+61
Split up hdmi_init() into hdmi_init() (done at hdmi sub-device bind/probe time) and hdmi_modeset_init() done from master driver's modeset_init(). Anything that can fail due to dependencies on other drivers which may be missing or not probed yet should go in hdmi_init(), so that devm error/cleanup paths work properly.

2014-09-16drm: backmerge tag 'v3.17-rc5' into drm-nextDave Airlie1-22/+24
This is requested to get the fixes for intel and radeon into the same tree for future development work. i915_display.c: fix missing dev_priv conflict.
2014-09-11drm/msm: Change nested function to static functionMark Charlebois1-22/+24
There is currently a nested function in Russel King's tree for the msm HDMI driver. The last nested function was removed from the Linux kernel when the Thinkpad driver was fixed. I believe nested functions are not desired upstream, and it also breaks compilation with clang so here is a patch to change the nested function into static function. The patch works with both clang and gcc. Signed-off-by: Mark Charlebois <charlebm@gmail.com> Signed-off-by: Rob Clark <robdclark@gmail.com>
2014-09-10drm/msm/mdp4: add LVDS panel supportRob Clark1-2/+2
LVDS panel support uses the LCDC (parallel) encoder. Unlike with HDMI, there is not a separate LVDS block, so no need to split things into a bridge+connector. Nor is there is anything re-used with mdp5. Note that there can be some regulators shared between HDMI and LVDS (in particular, on apq8064, ext_3v3p), so we should not use the _exclusive() variants of devm_regulator_get(). The drm_panel framework is used for panel-specific driver. Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-01-09drm/msm: add hdmi support for apq8x74/mdp5Rob Clark1-49/+150
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.

2013-08-24drm/msm: basic KMS driver for snapdragonRob Clark1-0/+235
The snapdragon chips have multiple different display controllers, depending on which chip variant/version. (As far as I can tell, current devices have either MDP3 or MDP4, and upcoming devices have MDSS.) And then external to the display controller are HDMI, DSI, etc. blocks which may be shared across devices which have different display controller blocks. To more easily add support for different display controller blocks, the display controller specific bits are split out into a "kms" module, which provides the kms plane/crtc/encoder objects. The external HDMI, DSI, etc. blocks are part encoder, and part connector currently. But I think I will pull in the drm_bridge patches from chromeos tree, and split them into a bridge+connector, with the registers that need to be set in modeset handled by the bridge. This would remove the 'msm_connector' base class. But some things need to be double checked to make sure I could get the correct ON/OFF sequencing.. This patch adds support for mdp4 crtc (including hw cursor), dtv encoder (part of MDP4 block), and hdmi. Signed-off-by: Rob Clark <robdclark@gmail.com>
