Both are for the same hardware each supporting a slight different subset of the hardware. The bf5xx-i2s driver supports 2 channel I2S mode while the bf5xx-tdm driver supports TDM mode and channel remapping. This patch adds support for TDM mode and channel remapping to the bf5xx-i2s driver so that we'll eventually be able to retire the bf5xx-tdm driver. Unfortunately the hardware is fixed to using 8 channels in TDM mode. The bf5xx-tdm driver jumps through a few hoops to make it work well with other channel counts as well: * Don't support mmap * Translate between internal frame size (which is always 8 * sample_size) and ALSA frame size (which depends on the channel count) * Have special copy and silence callbacks which are aware of the mismatch between internal and ALSA frame size * Reduce the maximum buffer size to ensure that there is enough headroom for dummy data. The bf5xx-i2s driver is going to use the same mechanisms when being used int TDM mode.
