Prepares for the future move of the PRM/CM code to drivers/. Also includes some prcm.[ch] cleanup patches from the WDTIMER cleanup series that don't need external acks. Basic test logs for this branch on top of v3.7-rc2 are here: http://www.pwsan.com/omap/testlogs/prcm_cleanup_a_3.8/20121021123719/ But due to the number of unrelated regressions present in v3.7-rc[12], it's not particularly usable as a testing base. With reverts, fixes, and workarounds applied as documented in: http://www.pwsan.com/omap/testlogs/test_v3.7-rc2/20121020134755/README.txt the following test logs were obtained: http://www.pwsan.com/omap/testlogs/prcm_cleanup_a_3.8/20121020231757/ which indicate that the series tests cleanly. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJQhEVeAAoJEMePsQ0LvSpLXMAP/R823zHuhSBsFYTAzoLpOsBu 1btfoXY+aTh/ZYQpn2zqbseHyBVoN7JuBNFA25UlgCIB/+tL2o+B62HQE3c31HZi zrOlUrSvIl7zYTLhbu8rezULSYGO3RHqtUGLJ9/RUV3su8zIATmHKgzA1f/aYH9x 2OKVIijXjvK4kKRpHhg8BGlD6stbuFDJbmik2/wgcO+159lKY6ZTRnHsj6PgZVIO BjbxpBujLYVBhJRJP0NNLVtGToGK54GvnHZxfVCu9oJ87n2amgaP6RHHHfEX0eMJ K65toYNIzZEmMahnazCcsiB+xK2Y2iiSZdOMPhH0FspCPTKTUl+czOlMGq7oyHmU xVmDyVHOVd5JRt5d985VlVScDrye06GxjWri557eeGcvOyQrlhJSntjdL2RZZaiu bpIhT1PRo8hqxtajcZlqBT7jSaH8kxQIQRXgGqJzY9iYLfUGU6DU7WYoqQTrrev7 aCZG8SnDbmltXMvhw13owDzy8xpdssCFaT8Fbxaxa6jq1GF1xyfEucDZDQPlZZd7 vbhdjYCBMiFcgJ3xWAmivboLPR1r5nZQdpwuYJTqoIvuJutB8Y0dJza7Dm0DGehc uJw/K/L/2qBdlOatFU4nk1c4AoTXZ+zn+ZVziTFus6ajhdB46C0i/vMLAXF68aDQ 23ow9fKjRsuHfKqjfzMP =asxx -----END PGP SIGNATURE----- Merge tag 'omap-cleanup-a-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.8/cleanup-prcm The first set of OMAP PRM/CM-related cleanup patches for 3.8.
