Subject: [PATCH RFT] watchdog: da9063_wdt: parse DT for timeout value, too
Date: Sun, 14 Apr 2019 13:09:33 +0200 [thread overview]
Message-ID: <20190414110933.30529-1-wsa+renesas@sang-engineering.com> (raw)
And make sure the final obtained value gets properly scaled. Remove two
empty lines to group the initialization blocks while we are here.
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

Tested with a Renesas Lager board (R-Car H2, DA9063AD), checking the initial
timeout value via sysfs. I didn't test handover from bootloader because my
bootloader neither supports WDT or I2C out of the box.
