The controller on J722S SoC is similar to the one present on TI's AM64 SoC, with the difference being that the controller on AM64 SoC supports up to Gen2 link speed while the one on J722S SoC supports Gen3 link speed. Update the bindings with a new compatible for J722S SoC. Technical Reference Manual of J722S SoC: https://www.ti.com/lit/zip/sprujb3 Signed-off-by: Siddharth Vadapalli --- Hello, This patch is based on linux-next tagged next-20240122. v1: https://lore.kernel.org/r/20240117102526.557006-1-s-vadapalli@ti.com/ Changes since v1: - Dropped patches 1/3 and 2/3 of the v1 series as discussed in the v1 thread. - Updated patch 3/3 which is the v1 for this patch by dropping the checks for the "num-lanes" property and "max-link-speed" property since the PCI driver already validates the "num-lanes" property. Regards, Siddharth.
