Merge tag 'asoc-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for 3.6 This has been a pretty quiet release - very little activity in framework terms, mostly just a few new drivers and updates: - Added the ability to add and remove DAPM paths dynamically, mostly for reparenting on clock changes. - New machine drivers for Marvell Brownstone, ST-Ericsson Ux500 reference platform and ttc-dkp. - New CPU drivers for Blackfin BF6xx SPORTs in I2S mode, Marvell MMP, Synopsis Designware I2S controllers, and SPEAr DMA and S/PDIF - New CODEC drivers for Dialog DA732x, ST STA529, ST-Ericsson AB8500, TI Isabelle and Wolfson Microelectronics WM5102 and WM5110
