Subject: [PATCH 1/2] ASoC: WM8962: mark cache_dirty flag after software reset in pm_resume
Date: Tue, 20 Oct 2015 11:47:11 +0900 [thread overview]
Message-ID: <1445309232-24094-2-git-send-email-jiada_wang@mentor.com> (raw)
In-Reply-To: <1445309232-24094-1-git-send-email-jiada_wang@mentor.com>
By doing software reset of wm8962 in pm_resume, all registers which
have already been set will be reset to default value without regmap
interface be involved, thus driver need to mark cache_dirty flag,
to let regcache can be updated by regcache_sync().
