Rob Herring 85d29c4d6e UPSTREAM: amba: Retry adding deferred devices at late_initcall ... If amba bus devices defer when adding, the amba bus code simply retries adding the devices every 5 seconds. This doesn't work well as it completely unsynchronized with starting the init process which can happen in less than 5 secs. Add a retry during late_initcall. If the amba devices are added, then deferred probe takes over. If the dependencies have not probed at this point, then there's no improvement over previous behavior. To completely solve this, we'd need to retry after every successful probe as deferred probe does. The list_empty() check now happens outside the mutex, but the mutex wasn't necessary in the first place. This needed to use deferred probe instead of fragile initcall ordering on 32-bit VExpress systems where the apb_pclk has a number of probe dependencies (vexpress-sysregs, vexpress-config).
