Currently drivers happen to work properly because reset is implicitly deasserted by tegra-clk driver, but clk driver shouldn't touch the resets and we need to fix it because this breaks other Tegra drivers. Previously we fixed the resets of the AHUB and HDMI codec drivers, but turned out that we missed the I2C and AC97 drivers. Thanks to Paul Fertser for testing the pending clk patches and finding that audio got broken on Tegra20 AC100 netbook because of the missing I2S reset. Changelog: v5: - After taking another look at the drivers I noticed couple more things that could be improved. These new patches correct runtime PM and probe/remove order of the drivers: ASoC: tegra20: spdif: Correct driver removal order ASoC: tegra20: spdif: Remove handing of disabled runtime PM ASoC: tegra20: i2s: Add system level suspend-resume callbacks ASoC: tegra20: i2s: Correct driver removal order ASoC: tegra20: i2s: Use devm_clk_get() ASoC: tegra20: i2s: Remove handing of disabled runtime PM ASoC: tegra30: i2s: Correct driver removal order ASoC: tegra30: i2s: Use devm_clk_get() ASoC: tegra30: i2s: Remove handing of disabled runtime PM ASoC: tegra30: ahub: Reset global variable ASoC: tegra30: ahub: Correct suspend-resume callbacks ASoC: tegra30: ahub: Remove handing of disabled runtime PM v4: - Added missing prototype for reset_control_bulk_put(). v3: - Fixed reset stubs for !CONFIG_RESET_CONTROLLER. v2: - After some more testing I found that I2S control logic doesn't require I2S clock to be enabled for resetting. Hence it's fine to have I2S to be reset by parent AHUB driver, so I dropped "tegra30: i2s: Add reset control" patch. - While I was double-checking resets on Tegra30, I found that that Tegra30 I2S driver has a broken runtime PM which doesn't restore hardware state on resume and it's lost after AHUB RPM-resume. Thus, added this new patch "tegra30: i2s: Restore hardware state on runtime PM resume". - Added new patches which switch AHUB driver to use reset-bulk API. I took the RFC patch from Philipp Zabel, fixed it and added devm_reset_control_bulk_optional_get_exclusive_released() that will be useful for further Tegra GPU patches. This is a minor improvement which makes code cleaner.
