drm/bridge/synopsys: dw-hdmi: fix dw_hdmi_setup_rx_sense

2018-05-30T17:42:39Z

The dw_hdmi_setup_rx_sense exported function should not use struct device to recover the dw-hdmi context using drvdata, but take struct dw_hdmi directly like other exported functions.

drm/bridge: analogix_dp: Split the platform-specific poweron in two parts

2018-04-24T06:34:49Z

Some of the platform-specific stuff in rockchip_dp_poweron() needs to happen before the generic code. Some needs to happen after. Let's split the callback in two. Specifically we can't start doing PSR work until _after_ the whole controller is up, so don't set the enable until the end. Cc: Kristian H.

drm/bridge: analogix_dp: Don't change psr while bridge is disabled

There is a race between AUX CH bring-up and enabling bridge which will cause link training to fail. To avoid hitting it, don't change psr state while enabling the bridge.

drm/bridge: analogix_dp: Don't create useless connectors

2018-03-07T15:18:00Z

If there is another bridge after analogix_dp, then the connector object should not be created. This fixes following timeouts on Exynos5420-based Chromebook2 Peach-PIT board during boot: exynos-dp 145b0000.dp-controller: AUX CH cmd reply timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout! exynos-dp 145b0000.dp-controller: AUX CH enable timeout!

drm/bridge: analogix: Do not use device's drvdata

2018-03-01T14:43:26Z

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.

drm/bridge/synopsys: dw-hdmi: don't clobber drvdata

2018-02-16T08:33:07Z

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.

drm/bridge/synopsys: dw-hdmi: Export some PHY related functions

2018-02-16T08:32:29Z

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.

drm/bridge/synopsys: stop clobbering drvdata

2018-01-09T13:34:38Z

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.

drm/bridge/sii8620: add remote control support

2017-10-11T11:14:25Z

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.
