Hi Dmitry,
Do you mean to move qmp_ufs_serdes_init , qmp_ufs_lanes_init and
qmp_ufs_pcs_init into a different wrapper function and call this wrapper
from qmp_ufs_init_registers for each table.
But for tbls_hs_b, we just need qmp_ufs_serdes_init and
qmp_ufs_pcs_init. qmp_ufs_lanes_init is not required for tbls_hs_b.
So wrapper API won't be of much help.
Regards,
Nitin
