+Subject: [PATCH] MIPS: ath79: fix CPU/DDR frequency calculation for SRIF PLLs
+
+Besides the CPU and DDR PLLs, the CPU and DDR frequencies
+can be derived from other PLLs in the SRIF block on the
+AR934x SoCs. The current code does not checks if the SRIF
+PLLs are used and this can lead to incorrectly calculated
+CPU/DDR frequencies.
+
+Fix it by calculating the frequencies from SRIF PLLs if
+those are used on a given board.
+
