[PATCH v2 0/2] media: i2c: ds90ub960: VC mapping improvements and TX1 support

From: Rishikesh Donadkar

Date: Mon Jul 20 2026 - 07:29:45 EST


This series improves virtual channel (VC) handling and adds TX1 port
support to the DS90UB960/UB9702 deserializer driver.

PATCH 01: Enable CSI TX1 port by parsing active RX/TX ports from
device tree and configuring RX_PORT_CTL BCC mapping
PATCH 02: Replace hardcoded VC-to-port-number assignment with a
proper per-port VC map built from source frame descriptors,
fix loop termination bug in ub960_get_vc_maps() that caused
ports after the first unconnected RX port to be skipped, and
add UB9702-specific VC mapping (4 bits/VC, 2 VCs per port)
instead of incorrectly reusing the UB960 layout

Tested streaming with the following configurations:
1. IMX219 + v3link on AM62A
2. ov2312 + v3link on AM62A
3. ov2312 + fusion2 on AM62A
