   4 Subject: [PATCH] MLK-14847: Revert "ASoC: fsl-sai: set xCR4/xCR5/xMR for SAI
   5  master mode"
   6
   7 This reverts commit c768ed336bba ("ASoC: fsl-sai: set xCR4/xCR5/xMR for
   8 SAI master mode")
   9
  10 This change was already introduced by commit 51659ca069ce ("ASoC: fsl-sai:
  11 set xCR4/xCR5/xMR for SAI master mode") from upstream.
  12
  13 Manually adjust the code to match the changes introduced by subsequent
  14 commit b2936555bb38 ("MLK-13609: ASoC: fsl_sai: fix for synchronize mode")
  15 by removing updates to FSL_SAI_TMR/FSL_SAI_RMR registers.
