548844b5cc Bugfix(i2s): fixed i2s left/right channels swapped issue for release/v3.2.
The right channel data is in the high position, so the I2S_TX_MSB_RIGHT & I2S_RX_MSB_RIGHT bits should be set.

62eb0f4c12 i2s: add (optional) support to clear tx descriptor in underflow case
It has been observed that, in case of underflow (data unavailability) in
I2S transmission, previously filled up tx descriptors continue to get
transmitted on line, causing noise in case of audio use case.

This change adds optional `tx_desc_auto_clear` field during I2S driver intialization
than can zero initialize tx descriptor in case of underflow situation in
interrupt handler itself.

Closes: https://github.com/espressif/esp-idf/issues/1789
(cherry picked from commit 765bf674d0)

b2a1a79eb4 i2s: fix issue in dma descriptor allocation if SPIRAM is enabled
It has been observed that, if external SPIRAM is enabled, then under
certain scenarios (e.g. internal memory being too much fragmented),
I2S tx/rx descriptors can land in external SPIRAM and hence resulting
in failure in DMA. Adding explicit capability to allocate in only DMA
capable memory.

a84db78eb1 bugfix(i2s): fix bck polarity issue when using pll clock.
reported from github: https://github.com/espressif/esp-idf/issues/1119

Digital team think it is due to the decimal divider.
We can reset the i2s tx and rx when calling i2s_stop to avoid this.
