Subject: [PATCH 8/8] ARM: OMAP2+: pdata-quirks: add PRM data for reset support
Date: Wed, 7 Aug 2019 10:48:59 +0300 [thread overview]
Message-ID: <1565164139-21886-9-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1565164139-21886-1-git-send-email-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.
