SoC changes for omaps for v4.11 merge window. This adds support
for keeping the interconnect target module active for uart if earlycon is specified. And we're adding Aaro Koskinen as a co-maintainer for omap1 to make sure things stay working for omap1. The other changes are mostly clean-up of old legacy code: - Remove unused omap_display_init() - Make omapdss_find_dss_of_node() function static - Add support for earlycon - Tidy up omap1 usb logging output with pr_cont - Make omap_otg_init() static - Delete redundant CPU class checks for omap1 - Remove unused mpurate cmdline option that has not done anything for past 1.5 years at least -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAliHc5MRHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXNVVBAAoNj2A8PfRJMYhQthtmUn0ORPe9QrF3k7 5WaIRWhithkRIJl+kVuGLTzR0Uqvzo1CCXug+rJxs0JQ6PJEe+cp++ygioZzjZwE t0oHugvT1+MYCM475OwMG9ajgKYBX/GMsWDmuuG5nLm1JRzWQfMAQsmuyP0Oey+D bWOC0Hlz1gHn2xrlvjZah54rkERaWnKUIdi1YMqAAjmh/RuDED5VNskOcacVbqI1 0C8wLC7mOviM3RyiQSCNTIKLC5illanjoZ/QHFnPLHV36KXJWCL/dB8gnAX+ORpF oCsL3t8erjq6cyhJIchs+UbqCEZv7HpIgbJBwc1oli3ExzS5iqmGQjhNkVN7Q+8Z TEQP6OhpPL4EXNEYOnE5pDgXATluWhD0rsg6XHt2CEsLZCOTzPTZCl0Of0vg3kcE eID7dz9CPXRquzyilVmyYla9Ty4XF3ePhdvLuI/06WgGU/M+6AvlZ40L8G73xKAu 0wHx2rpN0H4ySXsAtnyanCxld5njPGiLn5Ehmnib0CQU16Zxc6mbxVQVfaaSSbAu LJrLHBdeqWYEkUJV6n+lBg1WeCgL4qDolMTm8aRhESTCBHQEaLYXe57dluYCt0g2 2Rj1g/OuGFw+cViT2ICCvsAwE3jcHj32g8iJdnvfsypJ8pIO0znp2Sk7T7AYUXzw AafZ0ClGrws= =GiAL -----END PGP SIGNATURE----- Merge tag 'omap-for-v4.11/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc SoC changes for omaps for v4.11 merge window.
