FAMS is the successor to SubVP starting with DCN4x. Reuse the same
debug option to disable FAMS for debugging purposes.

drm/amd/display: Add a new dcdebugmask to allow skip detection LT2025-05-22T16:02:40ZWayne LinWayne.Lin@amd.com2025-05-20T01:34:42Zurn:sha1:076873e5b360ccd91687e23c6ca0042a0356b9eb
Under specific embedded scenarios, we might still use DP interface
rather than eDP interface. Under such case, detection link training
is unnecessary.
Add a new dcdebugmask value that can be used to skip the detection LT

drm/amd/display: Add a new dcdebugmask to allow turning off brightness curve2025-03-05T15:42:57ZMario Limonciellomario.limonciello@amd.com2025-02-28T18:51:45Zurn:sha1:36d63ce5dbc0dc37b5af90f6b7c3b92ab26403b7
Upgrading the kernel may cause some systems that were previously not using
a firmware specified brightness curve to use one.
In the event of problems with this curve (for example an interpolation
error) add a new dcdebugmask value that can be used to turn it off. Also
add an info message to show that custom brightness curves are currently in
use.

Some monitors flicker when subvp is enabled which maybe related to
an uncommon timing they use. To isolate such issues, add a debug
option to help isolate this the issue for debugging.
