Subject: arm64: dts: zynqmp: rtc: Update rtc calibration value
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8a32bc8b349d8488091c8b44735cb5868521cf17;p=thirdparty%2Fu-boot.git

arm64: dts: zynqmp: rtc: Update rtc calibration value

As per the design specification
"The 16-bit Seconds Calibration Value represents the number of
 Oscillator Ticks that are required to measure the largest time
 period that is less than or equal to 1 second.
 For an oscillator that is 32.768 KHz, this value will be 0x7FFF."
