drm/amd/display: Fix 6x4K displays light-up on Vega20 (v2)

2018-11-29T19:36:03+00:00

[Why]
More than 4x4K didn't lightup on Vega20 due to low dcfclk value.
Powerplay expects valid min requirement for dcfclk from DC.

[How]
Update min_dcfclock_khz based on min_engine_clock value.

v2: backport to 4.20 (Alex)

drm/amd/display: Fix misleading buffer information

2018-11-06T21:24:42+00:00

RETIMER_REDRIVER_INFO shows the buffer as a decimal value with a '0x'
prefix, which is somewhat misleading.

Fix it to print hexadecimal, as was intended.

drm/amd/display: Disable 4k 60 HDMI on DCE11

2018-10-25T01:04:18+00:00

[Why]
Carrizo and Stoney have severe corruption when trying to power
4k 60 monitors over HDMI connectors that support 4k 60.

Carrizo and Stoney require retimers and redrivers to support 4k 60
over HDMI.  This driver does not currently support these.  Thus, 4k 60
HDMI (and all other modes requiring over 300MHz) should be disabled.

[How]
Reduce the dce11 HDMI pixel clock cap to 300000kHz.

amd-gpu: Don't undefine READ and WRITE

2018-10-23T23:36:12+00:00

Remove the undefinition of READ and WRITE because these constants may be
used elsewhere in subsequently included header files, thus breaking them.

These constants don't actually appear to be used in the driver, so the
undefinition seems pointless.
