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/).
