CSIdrivers
CSIdrivers are software components that manage camera sensor interfaces in computing platforms. They implement the interface between image sensors that use the Camera Serial Interface (CSI), most commonly CSI-2, and the host processor. CSIdrivers are typically platform- and vendor-specific, delivered as kernel modules or drivers within an operating system's multimedia stack. They handle sensor initialization, clock and power management, lane configuration, and data routing to memory.
Core responsibilities include sensor enumeration and configuration over I2C or CCI, sensor power sequencing, MIPI D-PHY
Architectural context varies by platform. In Linux, CSI drivers are typically part of the media controller
Development and maintenance emphasize conformance with CSI-2 and its physical layer specifications, robust handling of clocking
