Subject: sky2: rename BMU register
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f449c7c10698e49e6c654452f852b1b719273d8a;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

sky2: rename BMU register

This register is more of a test and control register on Yukon2.
So rename it to Q_TEST and give some bit definitions.
