Renesas needs to finally start integrating the drivers and treating your
SoCs in unified way leading to unified kernel image. You have four
watchdog drivers, which look like could be combined into two drivers (so
each pair of drivers could be combined). For entire Qualcomm family
supporting more SoCs than Renesas there is only one driver.
