|
|
* The HDMI_DDC_INT_CTRL0 register is intended for HDCP 2.2 RxStatus
|
|
* register manipulation. It reads like this:
|
|
*
|
|
* Bit 31: RXSTATUS_MESSAGE_SIZE_MASK (1 = generate interrupt when size > 0)
|
|
* Bit 30: RXSTATUS_MESSAGE_SIZE_ACK (1 = Acknowledge message size intr)
|
|
* Bits 29-20: RXSTATUS_MESSAGE_SIZE (Actual size of message available)
|
|
* Bits 19-18: RXSTATUS_READY_MASK (1 = generate interrupt when ready = 1
|
|
* 2 = generate interrupt when ready = 0)
|
|
* Bit 17: RXSTATUS_READY_ACK (1 = Acknowledge ready bit interrupt)
|
|
* Bit 16: RXSTATUS_READY (1 = Rxstatus ready bit read is 1)
|
|
* Bit 15: RXSTATUS_READY_NOT (1 = Rxstatus ready bit read is 0)
|
|
* Bit 14: RXSTATUS_REAUTH_REQ_MASK (1 = generate interrupt when reauth is
|
|
* requested by sink)
|
|
* Bit 13: RXSTATUS_REAUTH_REQ_ACK (1 = Acknowledge Reauth req interrupt)
|
|
* Bit 12: RXSTATUS_REAUTH_REQ (1 = Rxstatus reauth req bit read is 1)
|
|
* Bit 10: RXSTATUS_DDC_FAILED_MASK (1 = generate interrupt when DDC
|
|
* tranasaction fails)
|
|
* Bit 9: RXSTATUS_DDC_FAILED_ACK (1 = Acknowledge ddc failure interrupt)
|
|
* Bit 8: RXSTATUS_DDC_FAILED (1 = DDC transaction failed)
|
|
* Bit 6: RXSTATUS_DDC_DONE_MASK (1 = generate interrupt when DDC
|
|
* transaction completes)
|
|
* Bit 5: RXSTATUS_DDC_DONE_ACK (1 = Acknowledge ddc done interrupt)
|
|
* Bit 4: RXSTATUS_DDC_DONE (1 = DDC transaction is done)
|
|
* Bit 2: RXSTATUS_DDC_REQ_MASK (1 = generate interrupt when DDC Read
|
|
* request for RXstatus is made)
|
|
* Bit 1: RXSTATUS_DDC_REQ_ACK (1 = Acknowledge Rxstatus read interrupt)
|
|
* Bit 0: RXSTATUS_DDC_REQ (1 = RXStatus DDC read request is made)
