This series improves the handling of clock and reset controls of NVIDA Tegra ALSA drivers. Tegra HDA and AHUB drivers aren't handling resets properly, which needs to be fixed in order to unblock other patches related to fixes on 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.

I wonder if this will help with the issues we saw when the tegra is the i2s clock slave. -- Ben Dooks http://www.codethink.co.uk/ Senior Engineer Codethink - Providing Genius https://www.codethink.co.uk/privacy.html
