Following, are the new features added and fixes from this patch-set: 1. Add support for drm_bridge On 8MQ and 8MM, the LCDIF block is not directly connected to a parallel display connector, where an LCD panel can be attached, but instead it is connected to DSI controller. Since this DSI stands between the display controller (eLCDIF) and the physical connector, the DSI can be implemented as a DRM bridge. So, in order to be able to connect the mxsfb driver to the DSI driver, the support for a drm_bridge was needed in mxsfb DRM driver (the actual driver for the eLCDIF block). 2. Add support for additional pixel formats Some of the pixel formats needed by Android were not implemented in this driver, but they were actually supported. So, add support for them. 3. Add support for horizontal stride Having support for horizontal stride allows the use of eLCDIF with a GPU (for example) that can only output resolution sizes multiple of a power of 8. For example, 1080 is not a power of 16, so in order to support 1920x1080 output from GPUs that can produce linear buffers only in sizes multiple to 16, this feature is needed. 3. Few minor features and bug-fixing The addition of max-res DT property was actually needed in order to limit the bandwidth usage of the eLCDIF block. This is need on systems where multiple display controllers are presend and the memory bandwidth is not enough to handle all of them at maximum capacity (like it is the case on 8MQ, where there are two display controllers: DCSS and eLCDIF). The rest of the patches are bug-fixes. v3: - Removed the max-res property patches and added support for max-memory-bandwidth property, as it is also implemented in other drivers - Removed unnecessary drm_vblank_off in probe v2: - Collected Tested-by from Guido - Split the first patch, which added more than one feature into relevant patches, explaining each feature added - Also split the second patch into more patches, to differentiate between the feature itself (additional pixel formats support) and the cleanup of the register definitions for a better representation (guido) - Included a patch submitted by Guido, while he was testing my patch-set Guido Günther (1): drm/mxsfb: Read bus flags from bridge if present Mirela Rabulea (1): drm/mxsfb: Signal mode changed when bpp changed Robert Chiras (13): drm/mxsfb: Update mxsfb to support a bridge drm/mxsfb: Add defines for the rest of registers drm/mxsfb: Reset vital registers for a proper initialization drm/mxsfb: Update register definitions using bit manipulation defines drm/mxsfb: Update mxsfb with additional pixel formats drm/mxsfb: Fix the vblank events drm/mxsfb: Add max-memory-bandwidth property for MXSFB dt-bindings: display: Add max-memory-bandwidth property for mxsfb drm/mxsfb: Update mxsfb to support LCD reset drm/mxsfb: Improve the axi clock usage drm/mxsfb: Clear OUTSTANDING_REQS bits drm/mxsfb: Add support for horizontal stride drm/mxsfb: Add support for live pixel format change .../devicetree/bindings/display/mxsfb.txt | 5 + drivers/gpu/drm/mxsfb/mxsfb_crtc.c | 287 ++++++++++++++++++--- drivers/gpu/drm/mxsfb/mxsfb_drv.c | 203 +++++++++++++-- drivers/gpu/drm/mxsfb/mxsfb_drv.h | 12 +- drivers/gpu/drm/mxsfb/mxsfb_out.c | 26 +- drivers/gpu/drm/mxsfb/mxsfb_regs.h | 193 +++++++++----- 6 files changed, 589 insertions(+), 137 deletions(-) -- 2.7.4
