2020-11-12drm: bridge: dw-hdmi: Avoid resetting force in the detect functionJonathan Liu1-6/+0
It has been observed that resetting force in the detect function can result in the PHY being powered down in response to hot-plug detect being asserted, even when the HDMI connector is forced on. Enabling debug messages and adding a call to dump_stack() in dw_hdmi_phy_power_off() shows the following in dmesg: [ 160.637413] dwhdmi-rockchip ff940000.hdmi: EVENT=plugin [ 160.637433] dwhdmi-rockchip ff940000.hdmi: PHY powered down in 0 iterations Call trace: dw_hdmi_phy_power_off dw_hdmi_phy_disable dw_hdmi_update_power dw_hdmi_detect dw_hdmi_connector_detect drm_helper_probe_detect_ctx drm_helper_hpd_irq_event dw_hdmi_irq irq_thread_fn irq_thread kthread ret_from_fork Fixes: 381f05a7a842 ("drm: bridge/dw_hdmi: add connector mode forcing") Signed-off-by: Jonathan Liu <[email protected]> Reviewed-by: Sam Ravnborg <[email protected]> Signed-off-by: Sam Ravnborg <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Add a new DRM bridge driver for Cadence MHDP8546 DPTX IP used in TI J721E SoC. MHDP DPTX IP is the component that complies with VESA DisplayPort (DP) and embedded Display Port (eDP) standards. It integrates uCPU running the embedded Firmware (FW) interfaced over APB interface. Basically, it takes a DPI stream as input and outputs it encoded in DP format. Currently, it supports only SST mode.

2020-09-15drm/bridge: ps8640: Rework power state handlingEnric Balletbo i Serra1-10/+58
The get_edid() callback can be triggered anytime by an ioctl, i.e drm_mode_getconnector (ioctl) -> drm_helper_probe_single_connector_modes -> drm_bridge_connector_get_modes -> ps8640_bridge_get_edid Actually if the bridge pre_enable() function was not called before get_edid(), the driver will not be able to get the EDID properly and display will not work until a second get_edid() call is issued and if pre_enable() is called before. The side effect of this, for example, is that you see anything when `Frecon` starts, neither the splash screen, until the graphical session manager starts. To fix this we need to make sure that all we need is enabled before reading the EDID. This means the following: 1. If get_edid() is called before having the device powered we need to power on the device. In such case, the driver will power off again the device. 2. If get_edid() is called after having the device powered, all should just work. We added a powered flag in order to avoid recurrent calls to ps8640_bridge_poweron() and unneeded delays. 3. This seems to be specific for this device, but we need to make sure the panel is powered on before do a power on cycle on this device. Otherwise the device fails to retrieve the EDID.

"Biggest" thing in here is the device link exposure in sysfs, to help to tame the madness that is SoC device tree representations and driver interactions with it. Other stuff in here that is interesting is: - device probe log helper so that drivers can report problems in a unified way easier. - devres functions added - DEVICE_ATTR_ADMIN_* macro added to make it harder to write incorrect sysfs file permissions - documentation cleanups - ability for debugfs to be present in the kernel, yet not exposed to userspace. Needed for systems that want it enabled, but do not trust users, so they can still use some kernel functions that were otherwise disabled. - other minor fixes and cleanups The patches outside of drivers/base/ all have acks from the respective subsystem maintainers to go through this tree instead of theirs.

With the bridge operations implemented the last step to prepare this driver for a chained setup is the use of the bridge panel driver. The bridge panel driver is only used when a port@2 is present in the DT. So when the display driver requests a connector support both situations: - connector created by bridge panel driver - connector created by this driver And on top, support that the display driver creates the connector, which is the preferred setup.

2020-07-27drm/bridge: parade-ps8622: add drm_panel_bridge supportSam Ravnborg1-87/+13
Prepare the bridge driver for use in a chained setup by replacing direct use of drm_panel with drm_panel_bridge support. The connecter is now either created by the panel bridge or the display driver. So all code for connector creation in this driver is no longer relevant and thus dropped. The connector code had some special polling handling: connector.polled = DRM_CONNECTOR_POLL_HPD; drm_helper_hpd_irq_event(ps8622->bridge.dev); This code was most likely added to speed up detection of the connector. If really needed then this functionality belongs somewhere else. Note: the bridge panel will use the connector type from the panel. v2: - Fix to avoid creating connector twice (Laurent) - Drop all connector code - defer to bridge panel - Use panel_bridge for local variable to align with other drivers - Set bridge.type to DRM_MODE_CONNECTOR_LVDS; Signed-off-by: Sam Ravnborg <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]> Cc: Andrzej Hajda <[email protected]> Cc: Neil Armstrong <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Jonas Karlman <[email protected]> Cc: Jernej Skrabec <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
