Subject: [PATCH v2 00/16] watchdog: refactor init_timeout and update users
Date: Tue, 16 Apr 2019 12:24:59 +0200	[thread overview]
Message-ID: <20190416102515.12269-1-wsa+renesas@sang-engineering.com> (raw)

When trying to add DT support to the DA9063 WDT, I didn't want to add yet
another error message when watchdog_init_timeout fails. The core could do this
with more detail, and also much more consistent. So, I refactored this routine
and removed error strings from its callers. Note that DA9063 support is not
added here but was sent seperately[1]. This series has been tested using the
renesas_wdt driver on a Renesas Salvator-XS board (R-Car M3N) and build bot is
happy, too.

Changes since V1:

* return -EINVAL if DT supplied a value of '0' [patch 1]
* update kdoc to mention that DT cannot be '0' but module_param can be
  [patch 1]
* add Guenter's Rev-by to all patches except patch 1
* add driver maintainers to CC this time

Looking forward to comments.

Thanks,

   Wolfram
