Subject: [PATCH v4 2/5] arm64: dts: allwinner: h6: add watchdog node
Date: Tue, 21 May 2019 18:03:27 +0200 [thread overview]
Message-ID: <20190521160330.28402-3-peron.clem@gmail.com> (raw)
In-Reply-To: <20190521160330.28402-1-peron.clem@gmail.com>
Allwinner H6 has a watchog node which seems broken
on some boards.
Test has been performed on several boards.
Chen-Yu Tsai boards:
Pine H64 - H6448BA 7782 => OK
OrangePi Lite 2 - H8068BA 61C2 => KO
Martin Ayotte boards:
Pine H64 - H8069BA 6892 => OK
OrangePi 3 - HA047BA 69W2 => KO
OrangePi One Plus - H7310BA 6842 => KO
OrangePi Lite2 - H6448BA 6662 => KO
Clément Péron board:
Beelink GS1 - H7309BA 6842 => KO
As it seems not fixable for now, declare the node
but leave it disable with a comment.
