cpufreq: ti-cpufreq: Add support for AM3517 (3fbeef39) · Commits · 戴 / test

The AM3517 only lists 600MHz @ 1.2V, but the register values for 0x4830A204 = 1b86 802f, it seems like am3517 might be a derivative of the omap36 which OPPs would be OPP50 (300 MHz) and OPP100 (600 MHz). This patch simply adds the am3517 to the compatible table similar to a mix of the omap3430 and omap3430 structure. Signed-off-by:
