Change the kconfig dependency to make bcm2835_wdt and bcm2835-rng available on ARCH_BCM2708 and ARCH_BCM2709. Enable them as loadable modules in bcmrpi_defconfig and bcm2709_defconfig. There is a commit in linux-next that will move restart/pm_power_off to bcm2835_wdt for ARCH_BCM2835. This will not affect ARCH_BCM270x since arm_pm_restart (.restart = bcm2708_restart) and pm_power_off (=bcm2708_power_off) is set in arch/arm/mach-bcm270X/bcm270X.c and will take presedence.

This makes it possible to use the mainline watchdog and random generator drivers: dtparam=watchdog=on dtparam=random=on bcm2708_wdog and bcm2708-rng can still be used. Signed-off-by: Noralf Trønnes <noralf@tronnes.org>

Looks good to me. This Device Tree stuff is quite useful... |
Yes, and overlays and parameters have made it very flexible and easy to use. |
