This adds DW-HDMI driver a glue option to disable loading of the CEC sub-driver. On some SoCs, the CEC functionality is enabled in the IP config bits, but the CEC bus is non-functional like on Amlogic SoCs, where the CEC config bit is set but the DW-HDMI CEC signal is not connected to a physical pin, leading to some confusion when the DW-HDMI CEC controller can't communicate on the bus.

2020-04-09drm/bridge: analogix_dp: Split bind() into probe() and real bind()Marek Szyprowski1-2/+3
Analogix_dp driver acquires all its resources in the ->bind() callback, what is a bit against the component driver based approach, where the driver initialization is split into a probe(), where all resources are gathered, and a bind(), where all objects are created and a compound driver is initialized. Extract all the resource related operations to analogix_dp_probe() and analogix_dp_remove(), then call them before/after registration of the device components from the main Exynos DP and Rockchip DP drivers. Also move the plat_data initialization to the probe() to make it available for the analogix_dp_probe() function. This fixes the multiple calls to the bind() of the DRM compound driver when the DP PHY driver is not yet loaded/probed: [drm] Exynos DRM: using 14400000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 14400000.fimd (ops fimd_component_ops [exynosdrm]) exynos-drm exynos-drm: bound 14450000.mixer (ops mixer_component_ops [exynosdrm]) exynos-dp 145b0000.dp-controller: no DP phy configured exynos-drm exynos-drm: failed to bind 145b0000.dp-controller (ops exynos_dp_ops [exynosdrm]): -517 exynos-drm exynos-drm: master bind failed: -517 ...

2020-03-06drm/bridge/mhl.h: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-2/+2
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2019-12-16drm/bridge/synopsys: dsi: driver-specific configuration of phy timingsHeiko Stuebner1-0/+9
The timing values for dw-dsi are often dependent on the used display and according to Philippe Cornu will most likely also depend on the used phy technology in the soc-specific implementation. To solve this and allow specific implementations to define them as needed add a new get_timing callback to phy_ops and call this from the dphy_timing function to retrieve the necessary values for the specific mode. Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling according to the phy speed, while STM seems to be ok with static values. changes in v5: - rebase on 5.5-rc1 - merge into px30 dsi series to prevent ordering conflicts changes in v4: - rebase to make it directly fit on top of drm-misc-next after all changes in v3: - check existence of phy_ops->get_timing in __dw_mipi_dsi_probe() - emit actual error when get_timing() call fails - add tags from Philippe and Yannick changes in v2: - add driver-specific handling, don't force all bridge users to use the same timings, as suggested by Philippe Suggested-by: Philippe Cornu <philippe.cornu@st.com> Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> Reviewed-by: Philippe Cornu <philippe.cornu@st.com> Tested-by: Yannick Fertre <yannick.fertre@st.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191209143130.4553-2-heiko@sntech.de

2019-06-11drm: bridge: dw-hdmi: Add hook for resumeDouglas Anderson1-0/+2
On Rockchip rk3288-based Chromebooks when you do a suspend/resume cycle: 1. You lose the ability to detect an HDMI device being plugged in. 2. If you're using the i2c bus built in to dw_hdmi then it stops working. Let's add a hook to the core dw-hdmi driver so that we can call it in dw_hdmi-rockchip in the next commit. NOTE: the exact set of steps I've done here in resume come from looking at the normal dw_hdmi init sequence in upstream Linux plus the sequence that we did in downstream Chrome OS 3.14. Testing show that it seems to work, but if an extra step is needed or something here is not needed we could improve it. As part of this change we'll refactor the hardware init bits of dw-hdmi to happen all in one function and all at the same time. Since we need to init the interrupt mutes before we request the IRQ, this means moving the hardware init earlier in the function, but there should be no problems with that. Also as part of this we now unconditionally init the "i2c" parts of dw-hdmi, but again that ought to be fine.

2018-10-30drm/bridge/synopsys: dsi: add ability to have glue-specific attach and detachHeiko Stuebner1-0/+8
With the regular means of adding the dsi-component in probe it creates a race condition with the panel probing, as the panel device only gets created after the dsi-bus got created. When the panel-driver is build as a module it currently fails hard as the panel cannot be probed directly: dw_mipi_dsi_bind() __dw_mipi_dsi_probe() creates dsi bus creates panel device triggers panel module load panel not probed (module not loaded or panel probe slow) drm_bridge_attach fails with -EINVAL due to empty panel_bridge Additionally the panel probing can run concurrently with dsi bringup making it possible that the panel can already be found but dsi-attach hasn't finished running. To solve that cleanly we may want to only create the component after the panel has finished probing, by calling component_add from the host-attach dsi callback. As that is specific to glue drivers, add a new struct for host_ops so that glue drivers can tell the bridge to call specific functions after the common host-attach and before the common host-detach run.

__dw_mipi_dsi_probe() does all the grabbing of resources and does it using devm-helpers. So this is happening on each try of master bringup possibly slowing down things a lot. Drivers using the component framework may instead want to call dw_mipi_dsi_probe separately in their probe function to setup resources early. That way the dsi bus also gets created earlier and also not recreated on each bind-try, so that attached panels can load their modules and be probed way before the bridge-attach in the bind call. So drop the call to __dw_mipi_dsi_probe and modify the function to take a struct dw_mipi_dsi instead of the platform-device.

2018-03-01drm/bridge: analogix: Do not use device's drvdataJeffy Chen1-8/+11
The driver that instantiates the bridge should own the drvdata, as all driver model callbacks (probe, remove, shutdown, PM ops, etc.) are also owned by its driver struct. Moreover, storing two different pointer types in driver data depending on driver initialization status is barely a good practice and in fact has led to many bugs in this driver. Let's clean up this mess and change Analogix entry points to simply accept some opaque struct pointer, adjusting their users at the same time to avoid breaking the compilation.

2018-02-16drm/bridge/synopsys: dw-hdmi: don't clobber drvdataJernej Skrabec1-6/+7
dw_hdmi shouldn't set drvdata since some drivers might need to store it's own data there. Rework dw_hdmi in a way to return struct dw_hdmi instead to store it in drvdata. This way drivers are responsible to store and pass structure when needed.

2018-02-16drm/bridge/synopsys: dw-hdmi: Export some PHY related functionsJernej Skrabec1-0/+11
Parts of PHY code could be useful also for custom PHYs. For example, Allwinner A83T has custom PHY which is probably Synopsys gen2 PHY with few additional memory mapped registers, so most of the Synopsys PHY related code could be reused. Functions exported here are actually not specific to Synopsys PHYs but to DWC HDMI controller PHY interface. This means that even if the PHY is completely custom, i.e. not designed by Synopsys, exported functions can be useful.

2018-01-09drm/bridge/synopsys: stop clobbering drvdataBrian Norris1-6/+11
Bridge drivers/helpers shouldn't be clobbering the drvdata, since a parent driver might need to own this. Instead, let's return our 'dw_mipi_dsi' object and have callers pass that back to us for removal.

MHL specification defines Remote Control Protocol(RCP) to send input events between MHL devices. The driver now recognizes RCP messages and reacts to them by reporting key events to input subsystem, allowing a user to control a device using TV remote control.
