[PATCH v2 0/3] ufs: Add callback for vendor-specific RTT capability

[ed.tsai at mediatek.com]

From: Ed Tsai <ed.tsai at mediatek.com>

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.

Changes in v2:
- Keep max_num_rtt field in patch 1 to maintain bisectability
- Split removal of max_num_rtt into a separate patch (patch 3)

Ed Tsai (3):
  ufs: core: Add get_hba_nortt callback for vendor-specific RTT
    capability
  ufs: mediatek: Implement get_hba_nortt callback for RTT capability
  ufs: core: Remove max_num_rtt field from ufs_hba_variant_ops
