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:

Use DPCD defines of drm_dp_helper.h; thus, duplicated DPCD defines of exynos_dp_core.h can be removed. Also, DP_TEST_EDID_CHECKSUM define is added to drm_dp_helper.h. There is no functional change. 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:

Exynos drm driver is a single driver so pm operation for kms drivers should be done by connector->dpms at top level driver. If kms driver has its own pm interfaces, single driver model would be broken so this patch removes unnecessary pm interfaces from dsi driver. Signed-off-by:

subdrv_probe callback of virtual display driver will be called by exynos_drm_device_subdrv_probe() to create crtc and encoder/connector for virtual display driver. So it fixes comments to exynos_drm_device_subdrv probe call. Signed-off-by:

Inki Dae authored
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:

This patch adds component framework support to resolve the probe order issue. Until now, exynos drm had used codes specific to exynos drm to resolve that issue so with this patch, the specific codes are removed. 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:

Daniel Kurtz authored
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:

DRM is pretty much the main user of this stuff (if we ignore the sysfs interface used by X, i.e. by the same gang of people writing the drm drivers). So shovel it into Dave's responsibility to avoid patches getting lost on lkml. With this get_maintainers will rout vgaarb and switcheroo patches correctly.

Started documenting drm properties for drm drivers. This patch provides information about properties in drm, i915, psb and cdv/gma-500. Information about other properties can be added on top of these. v2: Added description of drm properties in armada, exynos, i2c/ch7006, noveau, omap, qxl, radeon, rcar-du v3: Removed "Property Object" column since it is implementation related. Property type column refined.[Ville's review comments] v4: Removed whitespace warnings and minor nits. [Randy's review comments] v5: Restructured output for ENUM properties v6: Review comments on formatting the table. [Laurent's review comments] v7: Minor restructuring.

The 800x600 (SVGA) screen resolution was lacking in the set of built-in selectable EDID screen resolutions that can be used to repair misbehaving monitor firmware. This patch adds the related data set and expands the documentation. Note that the SVGA bit occupies a different byte to all the existing users of the established timing bits forcing a rework of the ESTABLISHED_TIMINGS_BITS macro. Tested new EDID on an aged (and misbehaving) industrial LCD panel; existing EDIDs still pass edid-decode's checksum checks. Signed-off-by:
