ASoC: tegra: update module reset list for Tegra124
Tegra124 adds a number of extra modules into the configlink bus, which must be taken out of reset before the bus is used. Update the AHUB driver to know about these extra modules (the AHUB HW module hosts the configlink bus). Based-on-work-by: Arun Shamanna Lakshmi <aruns@nvidia.com> Based-on-work-by: Songhee Baek <sbaek@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Mark Brown <broonie@linaro.org> --- This patch depends on "ASoC: tegra: use reset framework" to compile, which is ack'd and slated to go through a (large) topic branch in the Tegra tree. So, we can either: a) Merge that Tegra topic branch into the ASoC tree, then apply this. Note that I haven't created the topic branch yet, since I'm still waiting for DMA dependencies to be applied. b) Apply this change to the Tegra tree too. This change isn't directly related to the changes in the Tegra tree; it just makes use of the new reset controller feature that's introduced there.
