ARM: SoC fixes

We've been accruing these for a couple of weeks, so the batch is a bit bigger than usual. Largest delta is due to a led-bl driver that is added -- there was a miscommunication before the merge window and the driver didn't make it in. Due to this, the platforms needing it regressed. At this point, it seemed easier to add the new driver than unwind the changes. Besides that, there are a handful of various fixes: - AMD tee memory leak fix - A handful of fixlets for i.MX SCU communication - A few maintainers woke up and realized DEBUG_FS had been missing for a while, so a few updates of that. ... and the usual collection of smaller fixes to various platforms. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAl5lhi0PHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3C6gQAJHXpED85K94DH2jycwMFkWdGh+DnR1ATDaK +zK04ZanoQrtGi0mK0KY8DMaYCGCKvAgvBbRYdNXPK1S2DQfpZceSTiAN7fh6NJ2 F2XOGocH+IWrYmB+OA/rG6Sv2PFHibH34zf7TQ5w29jxCgv6zUTGF5qOoAnrhQzF SJNO08Ew0TjZ8mYXIoDHLsHaThT3rLF5f9yNMO0eG6gHrFKZHFfqhsDLqG6nSk+z L1M+WsfbxM0ijZDlIdJmxQLi4AlYkj3l8te4ikM6lngVSvQyYyEpnS2vw6h0OrZ9 y6PYw+gAzDOZgFSHqwwH/Ha2Or6eqS4eAv5JvIEqGhGslzNvmWc8FzElIG4qJKbu sshrcmTSe0Dt7W0zR8dsCY6tA2Ze1hpxbOpuhoh4H+dngANKAAMlko5s4Vw76ZYy B5mryFkyzyLI2QcZK/QmVQq2KSoeBOUg2SUtOrbBb5xQhhKCwhJBmJ0lw8H5O4dA TRNXL3p1ydve0z3DIKYCzM++MX1EJEa9O4uMTxKDPB6P9XrKvkx0rwC7wepc00jf /aXdVQsaQvnOYVs1R5oGISWLrheSJ28tHi3dI+xAdkdA26WWzPfomK9R7ok1/91T uuTpfmK6uhMvPkfg85/7n3/sojS6K9c0cP5wdd8Y0d2avvgQHCISgNZOZf3vlaYH xEcSJ4Vd =gCNz -----END PGP SIGNATURE----- Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Olof Johansson: "We've been accruing these for a couple of weeks, so the batch is a bit bigger than usual.
