* watchdog: constify watchdog_ops structuresBhumika Goyal2017-02-241-1/+1

This field is of type const, so watchdog_ops structures having this property can be made const too. Done using Coccinelle: @r disable optional_qualifier@ identifier x; position p; @@ static struct watchdog_ops x@p={...}; @ok@ struct watchdog_device w; identifier r.x; position p; @@ w.ops=&x@p; @bad@ position p != {r.p,ok.p}; identifier r.x; @@ x@p @depends on !bad disable optional_qualifier@ identifier r.x; @@ +const struct watchdog_ops x; File size details before and after patching.

* watchdog: mt7621_wdt: Remove assignment of dev pointerGuenter Roeck2016-09-241-1/+0
| | | | | | | | | | | | | | | | | | Commit 0254e953537c ("watchdog: Drop pointer to watchdog device from struct watchdog_device") removed the dev pointer from struct watchdog_device, but this driver was still assigning it, leading to a compilation error: drivers/watchdog/mt7621_wdt.c: In function 'mt7621_wdt_probe': drivers/watchdog/mt7621_wdt.c:142:16: error: 'struct watchdog_device' has no member named 'dev' Fix this by removing the assignment.

* watchdog: add MT7621 watchdog supportJohn Crispin2016-01-091-0/+186
This patch adds support for the watchdog core found on newer MediaTek Wifi SoCs MT7621 and MT7628. There is no symbol for MT7628 as it is a subtype of MT7620 so we depend on that instead.
