Subject: [PATCH 2/2] watchdog: mt7621-wdt: avoid ralink architecture dependent code
|
|
|
|
MT7621 SoC has a system controller node. Watchdog need to access to reset
|
|
status register. Ralink architecture and related driver are old and from
|
|
the beggining they are using some architecture dependent operations for
|
|
accessing this shared registers through 'asm/mach-ralink/ralink_regs.h'
|
|
header file. However this is not ideal from a driver perspective which can
|
|
just access to the system controller registers in an arch independent way
|
|
using regmap syscon APIs. Update Kconfig accordingly to select new added
|
|
dependencies and allow driver to be compile tested.
