0e09c4fa72 drm: Nuke mode->private_flags 
The last two uses of mode->private_flags (in i915 and gma500)
are now gone. So let's remove mode->private_flags entirely.

v2: Drop the earlier int->u8 conversion

adb48b2698 drm/dp_mst: Support remote i2c writes 
For DP MST outputs, the i2c device currently only supports transfers
that can be implemented using remote i2c reads. Such transfers must
consist of zero or more write transactions followed by one read
transaction. DDC/CI commands require standalone write transactions and
hence aren't supported.

Since each remote i2c write is handled as a separate transfer, remote
i2c writes can support transfers consisting of write transactions, where
all but the last have I2C_M_STOP set. According to the DDC/CI 1.1
standard, DDC/CI commands only require a single write or read
transaction in a transfer, so this is sufficient.

For i2c transfers meeting the above criteria, generate and send a remote
i2c write message for each transaction. Add the trivial remote i2c write
reply parsing support so remote i2c write acks bubble up correctly.

05ca530268 drm/vkms: avoid warning in vkms_get_vblank_timestamp 
This patch avoid the warning in vkms_get_vblank_timestamp when vblanks
aren't enabled. When running igt test kms_cursor_crc just after vkms
module, the warning raised like below. Initial value of vblank time is
zero and hrtimer.node.expires is also zero if vblank aren't enabled
before. vkms module isn't real hardware but just virtual hardware
module. so vkms can't generate a resonable timestamp when hrtimer is
off. it's best to grab the current time.

39cba5cf8c drm/vkms: add alpha-premultiplied color blending 
The VKMS blend function was ignoring the alpha channel and just
overwriting vaddr_src with vaddr_dst. This XRGB approach triggers a
warning when running the kms_cursor_crc/cursor-alpha-transparent test
case. In IGT, cairo_format_argb32 uses premultiplied alpha (according to
documentation). Also current DRM assumption is that alpha is
premultiplied. Therefore, this patch considers premultiplied alpha
blending eq to compose vaddr_src with vaddr_dst.

This change removes the following cursor-alpha-transparent warning:

 "Suspicious CRC: All values are 0."

V2:
- static for local functions
- const for the read-only variable argb_src
- replaces variable names
- drops unnecessary comment

3bc46a083f drm/sun4i: lvds: Invert the LVDS polarity 
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.

8b87014f23 drm/tidss: implement WA for AM65xx erratum i2000 
This patch implements WA for AM65xx erratum i2000, which causes YUV
formats to show wrong colors.

An earlier patch removed a partial WA:

a8d9d7da15 ("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.

The GPIO look-up-table is associated with the device directly
in the GMA500 Medfield chip driver since no explicit platform
type device (such as in x86/platform/intel-mid) exists: the
GMA500 probes directly from the PCI device. Apparently GPIOs
128 and 34 are used on all of these so just go ahead and
register those for resetting the DSI pipes.
