This is a revival of a series originally posted by Andrej Picej in
December 2021 [1]. It lets the DA9061/2 PMIC watchdog be configured via
the "dlg,wdt-sd" DT property, to trigger a full SHUTDOWN instead of the
default POWERDOWN on watchdog timeout, and enables that on the PHYTEC
phyCORE-i.MX6 SOM.
From v5 of original series this resend drops patch 4/5 ("dt-bindings:
watchdog: da9062: add watchdog timeout mode") because it already landed
upstream as commit 382256b219fb, later converted from .txt to YAML by
bd888a4377ae. Thus dlg,da9062-watchdog.yaml already documents dlg,wdt-sd
property.
Patches 1 and 2 (the mfd prerequisites making register CONFIG_I
writable) needed a rebase: an unrelated commit has since added
CONFIG_J, the register immediately adjacent to CONFIG_I, to the same
writeable-range tables. Rather than reapplying the original single-
register insert next to it, these merge CONFIG_I and CONFIG_J into one
range, matching the existing CONFIG_G-CONFIG_K style already used in
this file.
Patch 3 (the watchdog driver support) still applies unmodified.
Patch 4 only needed its target path updated for the arch/arm/boot/dts
vendor sub-directory move (imx6qdl-phytec-phycore-som.dtsi is now under
nxp/imx/); its content is unchanged.
Changes in v2:
Patch 1 and 2:
- capitalize subject description
Patch 3:
- implement Guenter's remarks (code refactor and update commit message)
Patch 4:
- capitalize subject description
