Tegra HDA and AHUB drivers aren't handling resets properly, which needs to be fixed in order to unblock other patches related to fixes of the reset controller driver since HDA/AHUB are bound to fail once reset controller driver will be corrected. In particular ALSA drivers are relying on implicit de-assertion of resets which is done by the tegra-clk driver. It's not the business of the clk driver to touch resets and we need to fix this because it breaks reset/clk programming sequences of other Tegra drivers. Changelog: v2: - Added regcache_sync() to the "ahub: Reset hardware properly" patch, which was missed by accident in v1. - Corrected typo in the format of the error message in "ahub: Use of_reset_control_array_get_exclusive()" patch by s/%p/%pe/.
