Hi York:
Currenly LS1012A is the only case. If there is other platform apply it in the future, we can add other platform later.

USB requires 100MHz clock. On ls1012, sysclk(125MHz) is not for USB. Another 100MHz clock is for USB. So For USB, check if sysclk is 100MHz is failed on ls1012, sysclk is not for USB. Don't check sysclk for USB on ls1012. Signed-off-by: Yingxi Yu <yingxi.yu@nxp.com> --- arch/arm/cpu/armv8/fsl-layerscape/fdt.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
