2016-03-02drm/dsi: Get DSI host by DT device nodeArchit Taneja1-0/+39
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().

2016-03-02drm/amdgpu: return from atombios_dp_get_dpcd only when errorArindam Nath1-1/+1
In amdgpu_connector_hotplug(), we need to start DP link training only after we have received DPCD. The function amdgpu_atombios_dp_get_dpcd() returns non-zero value only when an error condition is met, otherwise returns zero. So in case the function encounters an error, we need to skip rest of the code and return from amdgpu_connector_hotplug() immediately. Only when we are successfull in reading DPCD pin, we should carry on with turning-on the monitor.

2016-03-02drm/dsi: Try to match non-DT DSI devicesArchit Taneja1-1/+17
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 <[email protected]> Signed-off-by: Archit Taneja <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2016-03-02drm/dsi: Use mipi_dsi_device_register_full() for DSI device creationArchit Taneja1-17/+47
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.

2016-03-01drm/exynos: use real device for DMA-mapping operationsMarek Szyprowski7-46/+69
This patch changes device pointer provided to all calls to DMA-mapping subsystem from the virtual exynos-drm 'device' to the real device pointer of one of the CRTC devices (decon, fimd or mixer). This way no more hacks will be needed to configure proper DMA-mapping address space on the common virtual exynos-drm device. This change also removes the need for some hacks in IOMMU related code. It also finally solves the problem of Exynos DRM driver not working on ARM64 architecture, which provides noop-based DMA-mapping operations for virtual platform devices.

This patch adds a exynos5420 driver data to support mic_bypass option to bypass the mic from display out path. The mic(Mobile image compressor) compresses RGB data from fimd and send the compressed data to the mipi dsi. The bypass option can be founded from system register and the bit is 11. The option bit has been introduced since exynos5420. The only difference between exynos5250 and exynos5420/exynos5422 is existence of the bit.
