The cleanup branch keeps going down in size as we've completed a lot of the major legacy platform removals and conversions. A handful of changes this time around, some of the themes or larger sets are: - A bunch of i.MX cleanups around platform detection, init call cleanups - Misc fixes of missing/implicit includes - Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXnnwFAAoJEIwa5zzehBx3zXQP/2a/+XkiseeGkEoiX/6FOfhH XTzipye0OYdEe3kVWFL1sVVXRH6a5sbDJRNtfsQc+KdSG5i7LMHWARRJmIx9CTMB oQ9pEbYKSyBQDHBSOZYT6W+qYOI2SdTYqesjd3yn+FY4SIFBpQ/V3axHnMICIRm9 PmHF1QUQEdtQ2Y9+E1vA1mHcPN9enjlesD3VdRbxVPX/PZw63kx9y8ICVq5I/PX9 DfJRcA+PKIYQghhEZ0cx2bEoKozv7W088C7DD1Umw1NN18pMuvvNQGhid80xUqKY 4bmLSGWqwmSzv1WZ/u1pUnBGGQE9YY1U2b8kZy8hSVg9rupxS8Ang0ztZRRE6nk2 4t8GmWuLDH+7PxFv/skzi1AMAx+4KxSfp3N5qyKr8ddmnYrFWmBPj2AeBqrlziw6 8Z41LQULmf/Gs6McikGUP7ryqd15gNtTJO1wlavqFrPe0fyzcHsgqpIy3YCqZiSE wQ4Hc036xqGknmg6GjHWp+W1rHZVGsnXmvnp1IVRoAGqwBqxNi4ItIXE7an8144H NnWFmPRSsGg26MfEJVsbtPQWNtEGqM2lgr6zn9xirC0cVbQ4ZDtWp2q0bJ1v/cLQ sW6Gu6jgVN8YUPp56lBaXJ5RxHE9V1Sqi4/+KghBKWW0X/BIo99b6PVr2bJRrkaq ZvpvsgzbCHdGqTptF9Dw =SfR/ -----END PGP SIGNATURE----- Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "The cleanup branch keeps going down in size as we've completed a lot of the major legacy platform removals and conversions.
