5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Guiting Shen <aarongt.shen@xxxxxxxxx> [ Upstream commit f85739c0b2b0d98a32f5ca4fcc5501d2b76df4f6 ] The 8K sample parameter of 12.288Mhz main system bus clock doesn't work because the I2SC_MR.IMCKDIV must not be 0 according to the sama5d2 series datasheet(I2SC Mode Register of Register Summary). So use the 6.144Mhz instead of 12.288Mhz to support 8K sample.
