Add driver for TI SN65DSI83 Single-link DSI to Single-link LVDS bridge and TI SN65DSI84 Single-link DSI to Dual-link or 2x Single-link LVDS bridge. TI SN65DSI85 is unsupported due to lack of hardware to test on, but easy to add. The driver operates the chip via I2C bus. Currently the LVDS clock are always derived from DSI clock lane, which is the usual mode of operation. Support for clock from external oscillator is not implemented, but it is easy to add if ever needed. Only RGB888 pixel format is implemented, the LVDS666 is not supported, but could be added if needed. Reviewed-by:

The ChromeOS EC ANX7688 bridge is connected to a ChromeOS Embedded Controller, and is accessed using I2C tunneling through the Embedded Controller. Hence add a dependency on I2C_CROS_EC_TUNNEL, to prevent asking the user about this driver when configuring a kernel without support for the ChromeOS EC tunnel I2C bus.

This driver adds support for the ChromeOS EC ANX7688 HDMI to DP converter For our use case, the only reason the Linux kernel driver is necessary is to reject resolutions that require more bandwidth than what is available on the DP side. DP bandwidth and lane count are reported by the bridge via 2 registers and, as far as we know, only chips that have a firmware version greater than 0.85 support these two registers. Signed-off-by:

Douglas Anderson authored
Let's use the newly minted aux bus to break up the driver into sub drivers. We're not doing a full breakup here: all the code is still in the same file and remains largely untouched. The big goal here of using sub-drivers is to allow part of our code to finish probing even if some other code needs to defer. This can solve some chicken-and-egg problems. Specifically: - In commit 48834e60 ("drm/panel-simple: Support hpd-gpios for delaying prepare()") we had to add a bit of a hack to simpel-panel to support HPD showing up late. We can get rid of that hack now since the GPIO part of our driver can finish probing early. - We have a desire to expose our DDC bus to simple-panel (and perhaps to a backlight driver?). That will end up with the same chicken-and-egg problem. A future patch to move this to a sub-driver will fix it. - If/when we support the PWM functionality present in the bridge chip for a backlight we'll end up with another chicken-and-egg problem. If we allow the PWM to be a sub-driver too then it solves this problem. Signed-off-by:

This is a driver for video encoder with VGA and DVI/HDMI outputs. There is no documentation for the chip -- the operation was guessed from what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names come from the ch7035 driver in Mediatek's GPL code dump. Only bare minimum is implemented -- no fancy stuff, such as scaling. That would only worsen our misery. We don't load the firmware and we don't need to even bother enabling the MCU. There are probably no distributable firmware images anyway. Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60, with VGA as well as DVI. Signed-off-by:

Display connectors are modelled in DT as a device node, but have so far been handled manually in several bridge drivers. This resulted in duplicate code in several bridge drivers, with slightly different (and thus confusing) logics. In order to fix this, implement a bridge driver for display connectors. The driver centralises logic for the DVI, HDMI, VGAn composite and S-video connectors and exposes corresponding bridge operations. This driver in itself doesn't solve the issue completely, changes in bridge and display controller drivers are needed to make use of the new connector driver. Signed-off-by:

commit d6abe6df ("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).

Add a drm_bridge driver for the Toshiba TC358764 DSI to LVDS bridge. Changes in v4: - removed license blob, - ordered includes, - added error handling, - fixed reset GPIO handling, - added missing calls to the panel, - custom OF graph code replaced with helpers, - removed tc358764_poweroff from remove callback. v5: - fixed supply names, - fixed broken console - added connector to fb_helper, - added detach callback - unbinding works, - fixed typo in error checking code, - removed sparse bridge->encoder check - core does it already.
