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.
