Subject: [PATCHv5 10/10] ARM: OMAP2+: pdata-quirks: add PRM data for reset support
Date: Thu, 12 Sep 2019 14:39:16 +0300 [thread overview]
Message-ID: <20190912113916.20093-11-t-kristo@ti.com> (raw)
In-Reply-To: <20190912113916.20093-1-t-kristo@ti.com>
The parent clockdomain for reset must be in force wakeup mode, otherwise
the reset may never complete. Add pdata quirks for this purpose for PRM
driver.
