This series adds support for ARM's HDLCD display controller found in Juno and ARM TC2 Coretile. The HDLCD outputs an RGB stream that feeds into a single digital encoder (DVI or HDMI).
This series depends on Sudeep Holla's SCPI driver (now in mainline) and on the tda998x patches that have been queued on Russell's patch system here [1]. Only the Juno functionality has been tested as the TC2 Coretile require a working SiI9022 driver for VExpress that is not subject of this patchset. Changelog: v3: Changed the driver to use the memory-region phandle for bespoke framebuffers. v2: Added support for atomic modeset [2] v1: Original DRM submission [3] [1] http://www.arm.linux.org.uk/developer/patches/search.php?uid=2895 [2] http://lists.freedesktop.org/archives/dri-devel/2015-November/094177.html [3] http://lists.freedesktop.org/archives/dri-devel/2015-August/087685.html Best regards, Liviu Liviu Dudau (4): drm: arm: Add DT bindings documentation for HDLCD driver. drm: Add support for ARM's HDLCD controller. arm64: Juno: Add HDLCD support to the Juno boards.
