Hi all,
This series make an update in the MT7621 SoC's watchdog driver code. This
SoC already provides a system controller node to access reset status
register needed for the watchdog. Instead of using MIPS architecture
dependent operations in header 'asm/mach-ralink/ralink_regs.h' use
a phandle to the system controller node and use it through regmap APIs
from the code. Driver is also using some globals that are not needed at
all if a driver data structure is used along the code. Hence, add all
new needed stuff inside a new driver data structure. With this changes
driver can be properly compile tested.
Thanks in advance for reviewing this!
V1 of this series here [0].
Changes in v2:
- Remove no needed compatible 'syscon' from bindings.
- Rewrite new syscon phandle description in bindings.
- Remove 'syscon' from compatible in 'mt7621.dtsi'.
- Split PATCH 3 into two different patches:
- PATCH 3: removes static globals using a driver data structure.
- PATCH 4: remove ralink architecture dependent includes and code.
Best regards,
Sergio Paracuellos
