Samsung Continues Advancing Its Exynos DRM

Samsung has added S3C64XX SoC support to their Exynos DRM graphics driver, updated their DeviceTree support, and has begun utilizing the Common Clock Framework.

The changes that Samsung engineers have been lining up for to get into the Linux 3.11 kernel for their Direct Rendering Manager display driver are now known.

The S3C64XX SoC is now supported by Exynos DRM, which isn't new and is in fact an earlier version of Exynos. The S3C6410 ARM11 is one of the more well known SoCs in this family and can be found in navigation devices, smartphones, and other older systems.

The updated Device Tree support for the next kernel corrects some strings and adds in Exynos 5420 SoC support for the HDMI subsystem. The 3.11 version of this driver also begins to take advantage of CCF, the Common Clock Framework, but it's really not an end-user feature.

Besides therese changes, there's also "big cleanups" for the driver and the removal of unnecessary debug logs. More details can be found in the exynos-drm-next pull request for going into the DRM subsystem tree prior to its mainline merge in the coming days.
