2020-08-30drm: panel: Fix bpc for OrtusTech COM43H4M85ULC panelLaurent Pinchart
The OrtusTech COM43H4M85ULC panel is a 18-bit RGB panel. Commit f098f168e91c ("drm: panel: Fix bus format for OrtusTech COM43H4M85ULC panel") has fixed the bus formats, but forgot to address the bpc value. Set it to 6.

2020-08-27drm/sun4i: lvds: Invert the LVDS polarityMaxime Ripard
The LVDS controller can invert the polarity / lanes of the LVDS output. The default polarity causes some issues on some panels. However, U-Boot has always used the opposite polarity without any reported issue, and the only currently supported LVDS panel in-tree (the TBS A711) seems to be able to work with both settings. Let's just use the same polarity than U-Boot to be more consistent and hopefully support all the panels.

2020-08-21drm/tidss: implement WA for AM65xx erratum i2000Tomi Valkeinen
This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da1546349f18eb2d6b6b3a04bdeb38719d ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does.

2020-08-18drm/virtio: Support virtgpu exported resourcesDavid Stevens
Add support for UUID-based resource sharing mechanism to virtgpu. This implements the new virtgpu commands and hooks them up to dma-buf's get_uuid callback.

2020-08-18virtio-gpu: add VIRTIO_GPU_F_RESOURCE_UUID featureDavid Stevens
This feature allows the guest to request a UUID from the host for a particular virtio_gpu resource. The UUID can then be shared with other virtio devices, to allow the other host devices to access the virtio_gpu's corresponding host resource.

2020-08-18virtio: add dma-buf support for exported objectsDavid Stevens
This change adds a new flavor of dma-bufs that can be used by virtio drivers to share exported objects. A virtio dma-buf can be queried by virtio drivers to obtain the UUID which identifies the underlying exported object. Signed-off-by: David Stevens <stevensd@chromium.org> Acked-by: Michael S.

2020-08-17drm/virtio: Use struct_size() helper in kmalloc()Gustavo A. R. Silva
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes.

2020-08-17drm/qxl: don't take vga ports on rev5+Gerd Hoffmann
qemu 5.0 introduces a new qxl hardware revision 5. Unlike revision 4 (and below) the device doesn't switch back into vga compatibility mode when someone touches the vga ports. So we don't have to reserve the vga ports any more to avoid that happening.

This reverts commit d323bb44e4d23802eb25d13de1f93f2335bd60d0.
