Aligned the package layout with the concurrent Debian packaging conventions. Relocated package files under 'debian/bullseye/' and removed legacy paths under 'debian/'. Updated related build references to ensure compatibility with Bullseye. ca-certificate cluster-resource-agents dhcp dnsmasq haproxy libfdt lighttpd linuxptp lvm2 lsb openssl pf-bb-config stalld synce4l systemd watchdog Change-Id: Id31c289b6504433f2b739be614022cfed0c2a9b8 Signed-off-by: pmp1 <preetham.mp@windriver.com>

Subject: [PATCH 02/65] clock: Reset clock check on best clock/port change.
|
|
|
|
Reset the clock check when the best clock or port changes, together with
|
|
the other state like current estimated delay and frequency. This avoids
|
|
false positives if the clock is controlled by an external process when
|
|
not synchronized by PTP (e.g. phc2sys -rr).
