It receives commands over SCCB, an I2C-compatible protocol, at I2C address 0x36 and transmits data over CSI-MIPI. I confirmed this address experimentally. The pin control mapping was again extracted from the PinePhone Pro schematic v1.0 as well as the RK3399 datasheet revision 1.8. Table 2-3 in section 2.8 of the RK3399 datasheet contains the mapping of IO functions for the SoC pins. Page 52 shows GPIO1_A4, page 54 shows GPIO2_B4.
