Hi Amin, Thanks for the patch! On 9/21/26 17:30, Amin Gattout wrote:
The RK3576 Video Capture (VICAP) unit features a Digital Video Port (DVP) and five MIPI CSI-2 capture interfaces. Compared to the RK3588 variant, the MIPI register blocks are laid out differently (there is no block at offset 0x200), the ID_CTRL0 bit layout has changed, and the VC/DT filter has moved from ID_CTRL0 to ID_CTRL1. The capture size, which the other variants configure in ID_CTRL1, lives in the ID_SET_SIZE register. On the RK3576 the pixel clock of each MIPI port enters the VICAP through a dedicated CRU gate (CLK_VICAP_I0CLK to CLK_VICAP_I4CLK), so the variant claims these five clocks in addition to aclk, hclk and dclk.
