[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add definitions for registers grouped under Transcoder VRR function
with necessary bitfields.

Bspec: 50508 TRANS_VRR_CTL
Bspec: 50512 TRANS_VRR_VMAX
Bspec: 50514 TRANS_VRR_VMIN
Bspec: 50513 TRANS_VRR_VMAXSHIFT
Bspec: 50510 TRANS_VRR_STATUS
Bspec: 50515 TRANS_VRR_VTOTAL_PREV
Bspec: 50509 TRANS_VRR_FLIPLINE
Bspec: 50511 TRANS_VRR_STATUS2
Bspec: 50504 TRANS_PUSH
