[PATCH] arm:dts:k3-am64-sk: EMIF tool update to 0.8.0 with 1333MTs for lpddr4

2021-11-29 Thread Sinthu Raja
From: Sinthu Raja EMIF tool for AM64 SK is now updated to 0.8.0 that includes * disabled Write DQ training * improve CA ODT to 60 ohms The lpddr4 enabled with periodic WDQ training is causing periodic 26us stall. This makes the SoC stall without doing anything which leads to R5 interrupt latency
