drm/bridge: Drivers for megachips-stdpxxxx-ge-b850v3-fw (LVDS-DP++) The video processing pipeline on the second output on the GE B850v3: Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output Each bridge has a dedicated flash containing firmware for supporting the custom design. The result is that in this design neither the STDP4028 nor the STDP2690 behave as the stock bridges would. The compatible strings include the suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with the firmware which is specific for the GE B850v3. The driver is powerless to control the video processing pipeline, as the two bridges behaves as a single one. The driver is only needed for telling the host about EDID / HPD, and for giving the host powers to ack interrupts. This driver adds one i2c_device for each bridge, but only one drm_bridge. This design allows the creation of a functional connector that is capable of reading EDID from the STDP2690 while handling interrupts on the STDP4028.

drm/bridge: sil_sii8620: make remote control optional. commit d6abe6df706c ("drm/bridge: sil_sii8620: do not have a dependency of RC_CORE") changed the driver to select both RC_CORE and INPUT. However, this causes problems with other drivers, in particular an input driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate commit): drivers/clk/Kconfig:9:error: recursive dependency detected! drivers/clk/Kconfig:9: symbol COMMON_CLK is selected by MFD_INTEL_LPSS drivers/mfd/Kconfig:566: symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI drivers/mfd/Kconfig:580: symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI drivers/input/keyboard/Kconfig:73: symbol KEYBOARD_APPLESPI depends on INPUT drivers/input/Kconfig:8: symbol INPUT is selected by DRM_SIL_SII8620 drivers/gpu/drm/bridge/Kconfig:83: symbol DRM_SIL_SII8620 depends on DRM_BRIDGE drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_PL111 drivers/gpu/drm/pl111/Kconfig:1: symbol DRM_PL111 depends on COMMON_CLK According to the docs and general consensus, select should only be used for non user-visible symbols, but both RC_CORE and INPUT are user-visible. Furthermore almost all other references to INPUT throughout the kernel config are depends, not selects. For this reason the first part of this change reverts the commit. In order to address the original reason for the commit, namely that not all boards use the remote controller functionality and hence should not need have to deal with RC_CORE, the second part of this change now makes the remote control support in the driver optional and contingent on RC_CORE being defined. And with this the hard dependency on INPUT also goes away as that is only needed if RC_CORE is defined (which in turn already depends on INPUT).

drm/bridge: add support for sn65dsi86 bridge driver 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. Changes in v11: - Read DPPLL_SRC register to determine continuous clock instead of using refclk handle (Stephen Boyd). Changes in v12: - Explain in comment as in why dsi dev registration is done in bridge_attach (Andrzej Hajda). - Move HPD disable to bridge_pre_enable (Andrzej Hajda). - Make panel/DDC exclusive until HPD support is added (Andrzej Hajda). Changes in v13: - eDP panels report EDID via DP-AUX channel, so remove support for dedicated DDC line (Andrzej Hajda). Changes in v14: - Remove unnecessary drm_panel checks (Andrzej Hajda).
