Hello, third iteration for adv748x dynamic selection of video source. Please refer to v1 and v2 cover letter for more details: https://patchwork.kernel.org/cover/10723971/ https://patchwork.kernel.org/cover/10749535/ This version includes comments from Laurent and Kieran, on patches 1/6 and mostly on 6/6, which resulted in a better implementation. Thanks. I have tested this on Ebisu E3 where I can capture HDMI and CVBS inputs from TXA, and on Salvator-x M3-W where I can capture HDMI from TXA, and CVBS from both TXA and TXB, but only when setting the number of CSI-2 data lanes to 2 in DTS. It remains unresolved how to dynamically negotiate the number of CSI-2 data lanes to use between the video source and the CSI-2 receiver, which prevents using AFE->TXA routing on all Gen3 SoC which use 4 CSI-2 data lanes. The series is based on media tree master with the following series from Niklas applied on top: [PATCH v4 0/4] i2c: adv748x: add support for CSI-2 TXA to work in 1-, 2- and 4-lane mode Branch available for testing at: git://jmondi.org/linux adv748x_dynamic-routing_v3 Thanks j Jacopo Mondi (6): media: adv748x: Add is_txb() media: adv748x: Rename reset procedures media: adv748x: csi2: Link AFE with TXA and TXB media: adv748x: Store the source subdevice in TX media: adv748x: Store the TX sink in HDMI/AFE media: adv748x: Implement TX link_setup callback drivers/media/i2c/adv748x/adv748x-afe.c | 2 +- drivers/media/i2c/adv748x/adv748x-core.c | 74 +++++++++++++++++++----- drivers/media/i2c/adv748x/adv748x-csi2.c | 64 +++++++++++++------- drivers/media/i2c/adv748x/adv748x-hdmi.c | 2 +- drivers/media/i2c/adv748x/adv748x.h | 10 ++++ 5 files changed, 112 insertions(+), 40 deletions(-) -- 2.20.1
