PROTOCOLS
DsiImpl
Defined in fuchsia.hardware.dsiimpl/dsiimpl.fidl
Config
This function is used to configure all the DSI parameters needed to operated in both
Command and Video Mode
Request
Response
EnableBist
This function enable BIST pattern generation. This is useful during development stages
Request
Response
IsPoweredUp
This function return true if the DSI block is powered on and not in reset
Request
Response
PhyConfig
This function configures the PHY IP (inf within the DSI block)
Request
Response
PhyPowerDown
This function is used to power up the MIPI D-PHY block
Request
Response
PhyPowerUp
This function is used to power up the MIPI D-PHY block
Request
Response
PhySendCode
This function is used to communicate the MIPI D-PHY

Response
PhyWaitForReady
This function checks two things in order to decide whether the PHY is
ready or not. LOCK Bit and StopStateClk bit. According to spec, once these
are set, PHY has completed initialization
Request
Response
PowerDown
This function is called to power down the DSI interface
Request
Response
PowerUp
This function is called to power up the DSI interface
Request
Response
PrintDsiRegisters
This function prints the value of all DSI registers
Request
Response
ReadReg
This function returns the value of any register within the DSI IP block
Request
Response
Reset
This function resets the DSI IP block
Request
Response
SendCmd
This function is used to send a MIPI-DSI command through the DSI block
Request
Response
SetMode
This function is used to change modes between Video and Command.
Request
Response
WriteReg
This function allows writing to any register within the DSI block. This could be used
for debug purposes during development stages without needing to modify the DSI IMPL
protocol or to write to registers that don't really belong in the DSI IP block.
