* drm/bridge: analogix: Don't return -EINVAL when panel doesn't support PSRzain wang2016-12-071-2/+2
| | | | | | | | | | | We will ignored PSR setting if panel not support it. So, in this case, we should return from analogix_dp_enable/disable_psr() without any error code. Let's retrun 0 instead of -EINVAL when panel not support PSR in analogix_dp_enable/disable_psr().

| | * drm/bridge: Add ti-tfp410 DVI transmitter driverJyri Sarha2016-11-303-0/+325
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add very basic ti-tfp410 DVI transmitter driver. The only feature separating this from a completely dummy bridge is the EDID read support trough DDC I2C. Even that functionality should be in a separate generic connector driver. However, because of missing DRM infrastructure support the connector is implemented within the bridge driver. Some tfp410 HW specific features may be added later if needed, because there is a set of registers behind i2c if it is connected. This implementation is tested against my new tilcdc bridge support and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document is also updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reference from drm_dp_aux description (about transfer): Upon success, the implementation should return the number of payload bytes that were transferred, or a negative error-code on failure. Helpers propagate errors from the .transfer() function, with the exception of the -EBUSY error, which causes a transaction to be retried. On a short, helpers will return -EPROTO to make it simpler to check for failure. The analogix_dp_transfer will return num_transferred, but if there is none byte been transferred, the return value will be 0, which means success, we should return error-code if transfer none byte. for (retry = 0; retry < 32; retry++) { err = aux->transfer(aux, &msg); if (err < 0) { if (err == -EBUSY) continue; goto unlock; } } Cc: zain wang <wzz@rock-chips.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Jianqun Xu <jay.xu@rock-chips.com> Signed-off-by: Archit Taneja <architt@codeaurora.org> Link: http://patchwork.freedesktop.org/patch/msgid/1479255219-7243-1-git-send-email-jay.xu@rock-chips.com

The main purpose of this functionality is to support reading EDID from an HDMI monitor on boards, which don't have an I2C bus connected to DDC pins. The current implementation does not support "I2C Master Interface Extended Read Mode" to read data addressed by non-zero segment pointer, this means that if EDID has more than 1 extension blocks, EDID reading operation won't succeed, in my practice all tested HDMI monitors have at maximum one extension block.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to reduce the time required to turn on the panel, this patch makes 2 assumptions: 1- In detect(): if there's a panel, we're connected. 2- In get_modes(): if there's a panel, let the panel driver decide if it should prepare/unprepare in order to get the modes. The first is straightforward, and shouldn't need further explanation. The second should eliminate the prepare/unprepare delays from get_modes() in most cases, since panels generally hardcode their modes in the driver as opposed to reading EDID. If a panel does need to read EDID, it should be responsible for ensuring it's in a state in which it can. Signed-off-by: Sean Paul <seanpaul@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ADV7533 provides an internal timing generator for certain modes that it can't use the DSI clock directly. We've observed that HDMI is more stable with the internal timing generator, especially if there are instabilities in the DSI clock source. The data spec also seems to recommend the usage of the timing generator for all modes. However, on some platforms, it's reported that enabling the timing generator causes instabilities with the HDMI output. Create a DT parameter that lets a platform explicitly disable the timing generator. The timing generator is enabled by default. Signed-off-by: Archit Taneja <architt@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to pass DSI specific parameters to the DSI host, we need the driver to create a mipi_dsi_device DSI device that attaches to the host. Use of_graph helpers to get the DSI host DT node. Create a MIPI DSI device using this host. Finally, attach this device to the DSI host. Populate DT parameters (number of data lanes for now) that are required for DSI RX to work correctly. Hardcode few other parameters (rgb, embedded_sync) for now. Select DRM_MIPI_DSI config option only when ADV7533 support is enabled. Signed-off-by: Archit Taneja <architt@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ADV7533 is a DSI to HDMI encoder chip. It is a derivative of ADV7511, with additional blocks to translate input DSI data to parallel RGB data. Besides the ADV7511 I2C register map, it has additional registers that require to be configured to activate the DSI Rx block. Create a new config that enables ADV7533 support. Use DT compatible strings to populate the ADV7533 type enum. Add minimal register configurations belonging to the DSI/CEC register map. Keep the ADV7533 code in a separate file.
