The series is an based off v5.2-rc1 and has the following driver dependencies for a successful boot: 1. https://lore.kernel.org/lkml/20190429131533.25122-1-afd@ti.com (for newer firmware) 2. https://lore.kernel.org/linux-arm-kernel/1555093342-428-1-git-send-email-t-kristo@ti.com/ - Clock IDs cannot be guarenteed to be sequential, has to be discovered from hardware description in dts - Clock IDs on this massive chip also exceeds 255, so, the support for the same is expected in follow on patches. The full series is available here (including dependencies): https://github.com/nmenon/linux-2.6-playground/commits/upstream/v5.2-rc1/j7es-base-v1 Boot Log: https://pastebin.ubuntu.com/p/j3NtfF8FQr/ NOTE: - If Greg is ok, we can pick up the uart compatibility via the k3 tree, else, I can spawn it off the series. - I will resubmit patch 6 (defconfig update) separately once again once patches 1-5 hit the next tree or for 5.3-rc2 which ever is convenient. The J721E SoC belongs to the K3 Multicore SoC architecture platform for automotive applications such as infotainment, cluster, premium Audio, Gateway, industrial and a range of broad market applications. This SoC is designed around reducing the system cost by eliminating the need of an external system MCU and is targeted towards ASIL-B/C certification/requirements in addition to allowing complex software and system use-cases. The Linux development follows AM654 in most of the configurations, but adds new capabilities (details in follow on patches).
