The following configuration options combination: CONFIG_DRM_EXYNOS_DP=y CONFIG_DRM_PTN3460=m currently leads to the following linker failure: drivers/built-in.o: In function `exynos_drm_attach_lcd_bridge': .../drivers/gpu/drm/exynos/exynos_dp_core.c:1004: undefined reference to `ptn3460_init' This is because ptn3460_init can't be implemented in a module while its caller is built into the kernel. So add the proper dependency in Kconfig so that the above can't happen. I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module section, so that the user has a chance to select it before moving to the Exynos-specific section. IMHO the proper way to solve the problem would be to turn ptn3460 into a clean I2C driver, similar to the other I2C helper chip drivers. It's the only way to not sink into impossible-to-guess dependencies. Then ptn3460 could even be moved together with the other I2C helper chip drivers. Signed-off-by:

In case of exynos, setting dma-burst to 16Word causes permanent tearing for very small buffers, e.g. cursor buffer. Burst Mode switching, which is based on overlay size is not recommended as overlay size varies a lot towards the end of the screen. This causes unstable DMA which results into tearing again. Rendering small buffers with lower burst size doesn't cause any noticable performance overhead. 128 pixel width is selected based on mulitple experiments with exynos5 SoCs. Signed-off-by:

Exynos drm hdmi driver used to get dummy hdmiphy clock to control the PMU bit for hdmiphy. This bit needs to be set before setting any resolution to hdmi hardware. This was handled using dummy hdmiphy clock which is removed here. PMU is already defined as system controller for exynos SoCs. Hdmi driver is modified to control the phy enable bit inside PMU using regmap interfaces. Devicetree binding document for hdmi is also updated. Signed-off-by:

Allow to allocate non-contigous buffers when iommu is enabled. Currently, it tries to allocates contigous buffer which consistently fail for large buffers and then fall back to non contigous. Apart from being slow, this implementation is also very noisy and fills the screen with alloc fail logs. Signed-off-by:

This patch considers legacy dt binding, and resolves the issue that the use of existing dtb is broken. To resove the dt broken issue, this path tries to get legacy dt nodes from existing dtb directly prior to getting new dt nodes. Signed-off-by:

In DVI mode the video preamble and Guard band should be disabled whereas it should be applied in HDMI mode, the re-applying of preamble and guard band was missing, which resulted in display failures when switched to HDMI mode from DVI mode. This patch ensures the setting is applied in HDMI mode. Signed-off-by:

Before setting the core and timing generation registers, hdmi driver resets the whole hdmi hardware, which also resets the audio related registers. Hdmi reset is replaced by hdmi disable which is called just before setting the core and timing registers. It also ensure that audio settings are not changed. Signed-off-by:

This patch adds a gpio read of hpd during the is_connected callback. This fixes the case where hdmi is off going into suspend and the cable is plugged in while suspended. In this case, the hpd interrupt does not fire and is_connected will return false. Signed-off-by:

This patch debounces hotplug interrupts generated by the HDMI hotplug gpio. The reason this is needed is that we get multiple (5) interrupts every time a monitor is inserted which causes us to needlessly enable and disable the IP block. Signed-off-by:

This patch removes the hdmiphy reset in hdmi_poweroff. The hdmiphy reset was added to take advantage of exynos clockgating, doing it would gate the entire TV domain. Unfortunately, mixer is included in the TV domain and its vsync interrupts are stopped when TV is gated. Signed-off-by:

The recent commit [3ea87855: drm/helper: lock all around force mode restore] introduced drm_modeset_lock_all() in drm_helper_resume_force_mode() itself, while exynos driver takes this lock before calling it. Move the function call outside the lock for avoiding a deadlock. Signed-off-by:

Certain bridge chips use a GPIO to indicate the cable status instead of the I_DP_HPD pin. This adds an optional device-tree property, "samsung,hpd-gpio", to the exynos-dp controller which indicates that the specified GPIO should be used for hotplug detection. The GPIO is then set up as an edge-triggered interrupt where the rising edge indicates hotplug-in and the falling edge indicates hotplug-out. Signed-off-by:

When connector is created, if connector->polled is DRM_CONNECTOR_POLL_CONNECT then drm_kms_helper_hotplug_event function isn't called at drm_helper_hpd_irq_event because the function will be called only in case of DRM_CONNECTOR_POLL_HPD. So this patch sets always DRM_CONNECTOR_POLL_HPD flag to connector->polled of parallel panel driver at connector creation. Signed-off-by:

AFAICT, the fb_base of a drm_device's mode_config is never used. It isn't accessed by core drm, it isn't used by fbmem, and it isn't exposed to user space. Furthermore, it is probably supposed to be a physical address, not the dma address mapped to the display controller, so this is just wrong. Signed-off-by:

Kernel access to the eyxnos fbdev framebuffer is via its gem object's kernel mapping (kvaddr, stored in info->screen_base). User space access is provided by mmap(), read() and write() of /dev/fb/fb0. These functions also only use screen_base/screen_size(). Therefore, it is not necessary to set fix->smem_{start,len} or fix->mmio_{start,len} fields. This avoids leaking kernel, physical and dma mapped addresses to user space via the ioctls FBIOGET_VSCREENINFO and FBIOGET_FSCREENINFO. Signed-off-by:
