Merge patch series "ufs: Add callback for vendor-specific RTT capability"
ed.tsai@mediatek.com says:
The first patch adds the get_hba_nortt() callback to the UFS core
layer, allowing vendor drivers to provide dynamic, platform-specific
RTT capability handling.
The second patch implements this callback in the MediaTek UFS driver,
distinguishing between legacy platforms (which require the RTT to be
limited to 2) and newer MT6995 B0+ platforms (which can use the value
from the capability register directly).
The third patch removes the max_num_rtt field from ufs_hba_variant_ops
as it is now replaced by the get_hba_nortt() callback.
