A gpio is used to reset AD1980 on BF548-EZKIT,and this gpio will be cleared

during the suspend to memory/resume course,and causes the codec to be reset

again.So, from the power management point of view,it's not a good way to employ

a gpio to do the reset work.

guess we should report this to the board guys

can it be worked around by putting a pull up/down on the line ?

I just work around it by reconfiguring the codec after resume.

fixed now,we should deal with the scenario that,suspending to memory may happen

while the driver haven't been put into use yet,in such case,the related

registers are all reset and needed to be restored.
