A specific driver for ipq806x has been found in Qualcomm SDK repo. https://source.codeaurora.org/quic/qsdk/oss/kernel/linux-msm/commit/?h=release/endive_preview_cc&id=c089e464cd7ce652419a0dc44d7959ce4d24b8a5 https://source.codeaurora.org/quic/qsdk/oss/kernel/linux-msm/commit/?h=release/endive_preview_cc&id=c23d94b702c4182862e7f5051a2b7d00bb922a29 https://source.codeaurora.org/quic/qsdk/oss/kernel/linux-msm/commit/?h=release/endive_preview_cc&id=742f3684b62a6b9f082cb49404b1a92dc0b16bf5 https://source.codeaurora.org/quic/qsdk/oss/kernel/linux-msm/commit/?h=release/endive_preview_cc&id=c0a9b2e2a382c152fa128f5b864c800dd6dfb311 Merging it into LEDE with this commit.
