This patch adds new combatible strings for hdmi, mixer, ddc and hdmiphy. It follows the convention of using compatible string which represent the SoC in which the IP was added for the first time. Drivers continue to support the previous compatible strings but further addition of these compatible strings in device tree is deprecated.

Exynos5 is already using drm_display_mode for timings parameters. Exynos4 is also modifed to use the same. List of supported resolutions and corresponding timings are removed which helps is enabling some extra resolutions. It also cleans some of the duplicate code. Exynos4 and Exynos5 Mixers, work fine for the same range of resolutions. Hence same condition (to find the supported mode) is applied to both. More exynos4 phy configs can be added later to extend the mode supprot. Signed-off-by: NRahul Sharma <rahul.sharma@samsung.com> Signed-off-by: NInki Dae <inki.dae@samsung.com>

This patch adds the display mode check operation to exynos_mixer_ops in drm-common-hdmi. In Exynos SoCs, mixer IP can put certain restrictions on the proposed display modes. These restriction needs to be considered during mode negotiation, which happens immediately after edid parsing. Both, mixer check-mode and hdmi check-timing callbacks are called one after another and ANDed result is returned back.

Patch 9eb3e9e6 "drm/exynos: add support for ARCH_MULTIPLATFORM" allowed building the exynos hdmi driver on non-samsung platforms, which unfortunately broke compilation in combination with 22c4f428 "drm: exynos: hdmi: add support for exynos5 hdmi", which added an inclusion of the samsung-specific plat/gpio-cfg.h header file. Fortunately, that header file is not required any more here, so we can simply revert the inclusion in order to build the ARM allyesconfig again without getting this error: drivers/gpu/drm/exynos/exynos_hdmi.c:37:27: fatal error: plat/gpio-cfg.h: No such file or directory Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NInki Dae <inki.dae@samsung.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com>
