| * drm/exynos: replace hdmi reset with hdmi disableRahul Sharma2014-06-021-24/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

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

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

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

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

| * drm/exynos: restore parallel output interface supportAndrzej Hajda2014-03-245-0/+360
| | | | | | | | | | | | | | | | | | | | | | | | The patch adds parallel output interface to FIMD device driver. It also restores support for panels initialized by boot loader, but without proper kernel driver. Driver uses video interface bindings to find connected panel. It uses drm_panel interface to interact with the panel. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Reviewed-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

| * drm/exynos: delay fbdev initialization until an output is connectedAndrzej Hajda2014-03-242-12/+7
| | | | | | | | | | | | | | | | | | | | | | In case fbdev is initialized before any output is connected, fb resolution defaults to 1024x768. After that any output with bigger resolution is ignored and fbdev is not displayed. The patch postpones fbdev initialization to avoid such situation.
