watchdog: MIPS: lantiq: implement OF support and minor fixes
Add support for OF. We also apply the following small fixes * reduce boiler plate by using devm_request_and_ioremap * sane error path for the clock * move LTQ_RST_CAUSE_WDTRST to a soc specific header file * add a message to show that the driver loaded Signed-off-by: John Crispin <blogic@openwrt.org> Acked-by: Wim Van Sebroeck <wim@iguana.be> Cc: linux-watchdog@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3810/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
