Rename and add parameters to layer functions so they would represent HW more accurately and start using then. It turns out that overlays don't fit well in current DRM design, because they can't be blended together or scaled independetly when they are set to same channel.

2017-12-04drm/i915: Add "panel orientation" property to the panel connector, v6.Hans de Goede
Ideally we could use the VBT for this, that would be simple, in intel_dsi_init() check dev_priv->vbt.dsi.config->rotation, set connector->display_info.panel_orientation accordingly and call drm_connector_init_panel_orientation_property(), done. Unfortunately vbt.dsi.config->rotation is always 0 even on tablets with an upside down LCD and where the GOP is properly rotating the EFI fb in hardware. So instead we end up reading the rotation from the primary plane. This commit only implements the panel orientation property for DSI panels on BYT / CHT hardware, as all known non normal oriented panels sofar are only found on this hardware.

2017-12-04drm: Add support for a panel-orientation connector property, v6Hans de Goede
On some devices the LCD panel is mounted in the casing in such a way that the up/top side of the panel does not match with the top side of the device (e.g. it is mounted upside-down). This commit adds the necessary infra for lcd-panel drm_connector-s to have a "panel orientation" property to communicate how the panel is orientated vs the casing. Userspace can use this property to check for non-normal orientation and then adjust the displayed image accordingly by rotating it to compensate. Changes in v2: -Store panel_orientation in drm_display_info, so that drm_fb_helper.c can access it easily -Have a single drm_connector_init_panel_orientation_property rather then create and attach functions. The caller is expected to set drm_display_info.panel_orientation before calling this, then this will check for platform specific quirks overriding the panel_orientation and if the panel_orientation is set after this then it will attach the property.

2017-12-04drm: Add panel orientation quirks, v6.Hans de Goede
Some x86 clamshell design devices use portrait tablet screens and a display engine which cannot rotate in hardware, so the firmware just leaves things as is and we cannot figure out that the display is oriented non upright from the hardware. So at least on x86, we need a quirk table for this. This commit adds a DMI based quirk table which is initially populated with 5 such devices: Asus T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17. This quirk table will be used by the drm code to let userspace know that the display is not mounted upright inside the devices case through a new panel orientation drm-connector property, as well as to tell fbcon to rotate the console so that it shows the right way up. Changes in v5: -Add a kernel-doc comment documenting drm_get_panel_orientation_quirk() -Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop, keeping only the (identical) sys_vendor and product_name matches.

2017-12-04drm/prime: skip CPU sync in map/unmap dma_bufLucas Stach
Dma-bufs should already be device coherent, as they are only pulled in the CPU domain via the begin/end cpu_access calls. As we cache the mapping set up by dma_map_sg a CPU sync at this point will not actually guarantee proper coherency on non-coherent architectures, so we can as well stop pretending. This is an important performance fix for architectures which need explicit cache synchronization and userspace doing lots of dma-buf imports. Improves Weston on Etnaviv performance 5x, where before this patch > 90% of Weston CPU time was spent synchronizing caches for buffers which are already device coherent.
