Namely: 1) The driver doesn't get compiled when using the ARM64 defconfig [1]. 2) The children of the SPBA bus do not get probed [2]. These issues are addressed here by: 1) Enabling the driver config option in the ARM64 defconfig. 2) Replacing devm_of_platform_populate() with of_platform_populate() and passing a reference to the bus OF match table to it.
