Subject: phone-pad:phone-pad:battery bq27510 need to download firmware,but bq27541 don't need to,
X-Git-Tag: firefly_0821_release~9770^2~5
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a3b85277fd30f51a226c1feaf98ab3bc483b547b;p=firefly-linux-kernel-4.4.55.git

phone-pad:phone-pad:battery bq27510 need to download firmware,but bq27541 don't need to,
when we use bq27541 ,download firmware of bq27510 will damage bq27541.
so add a interface to check whether we need to download firmware.
