2019-01-09drm/bridge: tc358767: use DP connector if no panel setTomi Valkeinen
tc358767 driver sets the connector type always to eDP. This patch sets the type to DP if there is no panel defined, which implies that there's a DP connector on the board.

The current driver accepts any videomode with pclk < 154MHz. This is not correct, as with 1 lane and/or 1.62Mbps speed not all videomodes can be supported.

2019-01-09drm/bridge: tc358767: fix initial DP0/1_SRCCTRL valueTomi Valkeinen
Initially DP0_SRCCTRL is set to a static value which includes DP0_SRCCTRL_LANES_2 and DP0_SRCCTRL_BW27, even when only 1 lane of 1.62Gbps speed is used. DP1_SRCCTRL is configured to a magic number. This patch changes the configuration as follows: Configure DP0_SRCCTRL by using tc_srcctrl() which provides the correct value. DP1_SRCCTRL needs two bits to be set to the same value as DP0_SRCCTRL: SSCG and BW27. All other bits can be zero.

2018-11-15drm/bridge/sii902x: Fix EDID readbackFabrizio Castro
While adding SiI9022A support to the iwg23s board, it came up that when the HDMI transmitter is in pass through mode the device is not compliant with the I2C specification anymore, as it requires a far bigger tbuf, due to a delay the HDMI transmitter is adding when relaying the STOP condition on the monitor i2c side of things. When not providing an appropriate delay after the STOP condition the i2c bus would get stuck. Also, any other traffic on the bus while talking to the monitor may cause the transaction to fail or even cause issues with the i2c bus as well. I2c-gates seemed to reach consent as a possible way to address these issues, and as such this patch is implementing a solution based on that. Since others are clearly relying on the current implementation of the driver, this patch won't require any DT changes. Since we don't want any interference during the DDC Bus Request/Grant procedure and while talking to the monitor, we have to use the adapter locking primitives rather than the i2c-mux locking primitives.

2018-10-30drm/bridge/synopsys: dsi: add ability to have glue-specific attach and detachHeiko Stuebner
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.

2018-10-30drm/bridge/synopsys: dsi: don't call __dw_mipi_dsi_probe from dw_mipi_dsi_bindHeiko Stuebner
__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.

2018-10-29drm/bridge: ti-sn65dsi86: Remove the mystery delayDouglas Anderson
Let's solve the mystery of commit bf1178c98930 ("drm/bridge: ti-sn65dsi86: Add mystery delay to enable()"). Specifically the reason we needed that mystery delay is that we weren't paying attention to HPD. Looking at the datasheet for the same panel that was tested for the original commit, I see there's a timing "t3" that times from power on to the aux channel being operational. This time is specced as 0 - 200 ms. The datasheet says that the aux channel is operational at exactly the same time that HPD is asserted. Scoping the signals on this board showed that HPD was asserted 84 ms after power was asserted. That very closely matches the magic 70 ms delay that we had. ...and actually, in my testing the 70 ms wasn't quite enough of a delay and some percentage of the time the display didn't come up until I bumped it to 100 ms (presumably 84 ms would have worked too). To solve this, we tried to hook up the HPD signal in the bridge. ...but in doing so we found that that the bridge didn't report that HPD was asserted until ~280 ms after we powered it (!). This is explained by looking at the sn65dsi86 datasheet section "8.4.5.1 HPD (Hot Plug/Unplug Detection)". Reading there we see that the bridge isn't even intended to report HPD until 100 ms after it's asserted. ...but that would have left us at 184 ms. The extra 100 ms (presumably) comes from this part in the datasheet: > The HPD state machine operates off an internal ring oscillator. The > ring oscillator frequency will vary [ ... ]. The min/max range in > the HPD State Diagram refers to the possible times based off > variation in the ring oscillator frequency. Given that the 280 ms we'll end up delaying if we hook up HPD is _slower_ than the 200 ms we could just hardcode, for now we'll solve the problem by just hardcoding a 200 ms delay in the panel driver using the patch in this series ("drm/panel: simple: Support panels with HPD where HPD isn't connected"). If we later find a panel that needs to use this bridge where we need HPD then we'll have to come up with some new code to handle it. Given the silly debouncing in the bridge chip, though, it seems unlikely. One last note is that I tried to solve this through another way: In ti_sn_bridge_enable() I tried to use various combinations of dp_dpcd_writeb() and dp_dpcd_readb() to detect when the aux channel was up. In theory that would let me detect _exactly_ when I could continue and do link training. Unfortunately even if I did an aux transfer w/out waiting I couldn't see any errors. Possibly I could keep looping over link training until it came back with success, but that seemed a little overly hacky to me.

If we don't have the delay, link training fails.

2018-07-27drm/bridge: add support for sn65dsi86 bridge driverSandeep Panda
Add support for TI's sn65dsi86 dsi2edp bridge chip. The chip converts DSI transmitted signal to eDP signal, which is fed to the connected eDP panel. This chip can be controlled via either i2c interface or dsi interface. Currently in driver all the control registers are being accessed through i2c interface only. Also as of now HPD support has not been added to bridge chip driver. Changes in v1: - Split the dt-bindings and the driver support into separate patches (Andrzej Hajda). - Use of gpiod APIs to parse and configure gpios instead of obsolete ones (Andrzej Hajda). - Use macros to define the register offsets (Andrzej Hajda). Changes in v2: - Separate out edp panel specific HW resource handling from bridge driver and create a separate edp panel drivers to handle panel specific mode information and HW resources (Sean Paul). - Replace pr_* APIs to DRM_* APIs to log error or debug information (Sean Paul). - Remove some of the unnecessary structure/variable from driver (Sean Paul). - Rename the function and structure prefix "sn65dsi86" to "ti_sn_bridge" (Sean Paul / Rob Herring). - Remove most of the hard-coding and modified the bridge init sequence based on current mode (Sean Paul). - Remove the existing function to retrieve the EDID data and implemented this as an i2c_adapter and use drm_get_edid() (Sean Paul). - Remove the dummy irq handler implementation, will add back the proper irq handling later (Sean Paul). - Capture the required enable gpios in a single array based on dt entry instead of having individual descriptor for each gpio (Sean Paul). Changes in v3: - Remove usage of irq_gpio and replace it as "interrupts" property (Rob Herring). - Remove the unnecessary header file inclusions (Sean Paul). - Rearrange the header files in alphabetical order (Sean Paul). - Use regmap interface to perform i2c transactions. - Update Copyright/License field and address other review comments (Jordan Crouse). Changes in v4: - Update License/Copyright (Sean Paul). - Add Kconfig and Makefile changes (Sean Paul). - Drop i2c gpio handling from this bridge driver, since i2c sda/scl gpios will be handled by i2c master. - Update required supplies names. - Remove unnecessary goto statements (Sean Paul). - Add mutex lock to power_ctrl API to avoid race conditions (Sean Paul). - Add support to parse reference clk frequency from dt(optional). - Update the bridge chip enable/disable sequence. Changes in v5: - Fixed Kbuild test service reported warnings. Changes in v6: - Use PM runtime based ref-counting instead of local ref_count mechanism (Stephen Boyd). - Clean up some debug logs and indentations (Sean Paul). - Simplify dp rate calculation (Sean Paul). - Add support to configure refclk based on input REFCLK pin or DACP/N pin (Stephen Boyd). Changes in v7: - Use static supply entries instead of dynamic allocation (Andrzej Hajda). - Defer bridge driver probe if panel is not probed (Andrzej Hajda). - Update of_graph APIs for correct node reference management. (Andrzej Hajda). - Remove local display_mode object (Andrzej Hajda). - Remove version id check function from driver. Changes in v8: - Move dsi register/attach function to bridge driver probe (Andrzej Hajda). - Introduce a new helper function to write 16bit words into consecutive registers (Andrzej Hajda). - Remove unnecessary macros (Andrzej Hajda). Changes in v9: - Remove dsi register/attach from bridge probe, since dsi dev register completion also waits for any panel or bridge to get added. This creates deadlock situation when bridge driver calls dsi dev register and attach before bridge add, in its probe function. - Fix issues faced during testing of bridge driver on actual HW. - Remove unnecessary initializations (Stephen Boyd). - Use local refclk lut size instead of global macro (Sean Paul). Changes in v10: - Use refclk to determine if continuous dsi clock is needed or not.

2018-07-10drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULLBoris Brezillon
Right now, the DRM panel logic returns NULL when a panel pointing to the passed OF node is not present in the list of registered panels. Most drivers interpret this NULL value as -EPROBE_DEFER, but we are about to modify the semantic of of_drm_find_panel() and let the framework return -ENODEV when the device node we're pointing to has a status property that is not equal to "okay" or "ok". Let's first patch the of_drm_find_panel() implementation to return ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace the '!panel' check by an 'IS_ERR(panel)' one.
