| |
D1 keeps the same register layout and clock sources as the R329, but it adds a key field which must be set to update the watchdog's "CFG" and "MODE" registers. Therefore it is not backward-compatible.
Similarly to the R329, the D1 has three watchdog instances, and only one of them has the "soft reset" registers. So that instance needs an extra compatible string.
Signed-off-by: Samuel Holland <samuel@sholland.org> --- Changes v2 to v3: - Add additional allwinner,sun20i-d1-wdt-reset compatible Changes v1 to v2: - None
