drm: dsi: Add lane clock rate fields to DSI device

2018-10-24T14:26:35Z

The DSI devices have a maximum operating frequency specified in their data sheet per the MIPI specification, and DSI hosts that can scale their frequency need this information to set their clock dividers right. As current panel drivers often lack this information, specify that setting it to zero will make the DSI host use some reasonable default.

drm/dsi: Order DCS helpers by command code

Most of these helpers had been introduced in the correct order, but some were simply appended, which wasn't detected when they were applied. Signed-off-by: Thierry Reding

drm/dsi: Add uevent callback

Implement a uevent callback for devices on the MIPI DSI bus. This callback will append MODALIAS information to the uevent and allow modules to be loaded when devices are added to the bus. Reviewed-by: Archit Taneja Signed-off-by: Thierry Reding

drm/dsi: Get DSI host by DT device node

2016-03-02T16:02:54Z

MIPI DSI devices are inherently aware of their host because they share a parent-child hierarchy in the device tree. Non-DSI drivers that create DSI device don't have this data. In order to get this information, they require to a phandle to the DSI host in the device tree. Maintain a list of all the DSI hosts that are currently registered. This list will be used to find the struct mipi_dsi_host corresponding to the device tree node passed to of_find_mipi_dsi_host_by_node().

drm/dsi: Add routine to unregister a DSI device

2016-03-02T16:02:10Z

A driver calling mipi_dsi_device_register_full() might want to remove the device once it's done. It might also require it in an error handling path in case something went wrong. Create mipi_dsi_device_unregister() for this purpose and use it within mipi_dsi_remove_device_fn() as it does the same thing.

drm/dsi: Try to match non-DT DSI devices

2016-03-02T16:01:09Z

Add a device name field in struct mipi_dsi_device. This name is not the same as the device name (which is of the format "hostname.reg"). When the device is created via DT, this name is set to the modalias string. In the non-DT case, the driver creating the DSI device provides the name by populating a field in struct mipi_dsi_device_info. Matching for DT case would be as it was before. For the non-DT case, we compare the device and driver names. Other buses (like I2C/SPI) perform a non-DT match by comparing the device name and entries in the driver's id_table. Such a mechanism isn't used for the DSI bus. Reviewed-by: Andrzej Hajda Signed-off-by: Archit Taneja Signed-off-by: Thierry Reding

drm/dsi: Use mipi_dsi_device_register_full() for DSI device creation

2016-03-02T16:00:18Z

Use mipi_dsi_device_register_full() for device creation. This takes in a struct mipi_dsi_device_info as a template to populate the DSI device information. The reason to introduce this is to have a way to create DSI devices not available via DT. Drivers that want to create a DSI device can populate a struct mipi_dsi_device_info and call this function. For DSI devices available via DT, of_mipi_dsi_device_add() is used as before, but this now calls mipi_dsi_device_register_full() internally. Signed-off-by: Archit Taneja Signed-off-by: Thierry Reding
