* | | drm/exynos/hdmi: add PHY power off signal handlingAndrzej Hajda2016-04-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDMI-PHY power off bit defaults to 0 in older HDMI versions. In case of Exynos5433 it defaults to 1. To make code consistent across all versions this bit is always unset/set in power on/off sequences. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
* | | drm/exynos/hdmi: fix PHY configuration sequenceAndrzej Hajda2016-04-301-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Proper PHY configuration should be as follow: 1. set HDMI clock parents to OSCCLK. 2. reconfigure PHY. 3. set HDMI clock parents to PHY. 4. wait for PLL stabilization. The patch fixes it and consolidates the code. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HDMI on Exynos5433 differs from previous versions: - different HDMI-PHY settings, - different clocks, - SYSREG registers for enabling reference clock, - MODE_SET register in HDMI-PHY.

* | | drm/exynos: Use VIDEO_SAMSUNG_S5P_G2D=n as G2D Kconfig dependencyJavier Martinez Canillas2016-04-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 254d4d111ee1 ("drm/exynos: Add dependency for G2D in Kconfig") made the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver is not enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m if VIDEO_SAMSUNG_S5P_G2D=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the dp core driver from exynos directory to bridge directory, and rename the core driver to analogix_dp_*, rename the platform code to exynos_dp. Beside the new analogix_dp driver would export six hooks. "analogix_dp_bind()" and "analogix_dp_unbind()" "analogix_dp_suspned()" and "analogix_dp_resume()" "analogix_dp_detect()" and "analogix_dp_get_modes()" The bind/unbind symbols is used for analogix platform driver to connect with analogix_dp core driver. And the detect/get_modes is used for analogix platform driver to init the connector. They reason why connector need register in helper driver is rockchip drm haven't implement the atomic API, but Exynos drm have implement it, so there would need two different connector helper functions, that's why we leave the connector register in helper driver.

| | | | | | | | | | | | | | 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.

The option bit has been introduced since exynos5420. The only difference between exynos5250 and exynos5420/exynos5422 is existence of the bit.
