Subject: dt: bcm6858: watchdog should use a 50Mhz clock
X-Git-Tag: v2019.07-rc3~22^2~14
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a328ada4413f3ad911dc03bcd73ca0707c128e23;p=oweals%2Fu-boot.git

dt: bcm6858: watchdog should use a 50Mhz clock

The watchdog should use a clock at 50 Mhz, so
instead of using the clock osc (200 Mhz), we
define a reference clock at 50Mhz and use it
for both watchdog.
