Dirk Behme 5a5ca56e05 ARM: dts: i.MX6: configure L2 cache data and tag latency
Configure the data and tag latency for the L2 cache. This improves the
system performance.

This configuration is taken from Freescale's kernel patch

"ENGR00153601 [MX6]Adjust L2 cache parameter" [1]

which does

writel(0x132, IO_ADDRESS(L2_BASE_ADDR + L2X0_TAG_LATENCY_CTRL));
writel(0x132, IO_ADDRESS(L2_BASE_ADDR + L2X0_DATA_LATENCY_CTRL));

In this patch we are doing the same via the device tree.
