Subject: p1_p2_rdb: to set SQW/INT pin of RTC as INT line
X-Git-Tag: v2010.12-rc2~79^2^2~5
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=39c2a6eb75fabd9745c5762c8dec9d1a85dabf00;p=oweals%2Fu-boot.git

p1_p2_rdb: to set SQW/INT pin of RTC as INT line

SQW/INT pin in RTC can be used for generating square wave(by default) or
as interrupt line.  U-boot is registering this pin for interrupts.
Configuring SQW/INT bit as interrupt line during board initialization
to avoid spurious interrupts generated by square wave.
