I2S reset failures are seen on Tegra210 and later platforms. This indicates
absence of I2S bit clock, which is required to perform the reset operation.
Following failures are seen with I2S based tests on Tegra210 and later:
tegra210-i2s 2901100.i2s: timeout: failed to reset I2S for playback
tegra210-i2s 2901100.i2s: ASoC: PRE_PMU: I2S2 RX event failed: -110
tegra210-i2s 2901100.i2s: timeout: failed to reset I2S for capture
tegra210-i2s 2901100.i2s: ASoC: PRE_PMU: I2S2 TX event failed: -110
The commit d92ad6633fa7 ("ASoC: tegra: Update to use set_fmt_new callback")
regressed I2S functionality on Tegra platforms. Basically it flipped clock
provider and consumer DAI formats. This configures Tegra I2S in consumer
mode by default now and there is none to provide bit clock during loopback
tests. The external codec based tests also fail because both Tegra I2S and
codec I2S get configured in consumer mode.
ASoC core flips the DAI format before calling set_fmt() for CPU DAIs. This
is negated in above commit. Fix this by swapping SND_SOC_DAIFMT_BC_FC and
SND_SOC_DAIFMT_BP_FP switch cases.
