Subject: [PATCH AUTOSEL 5.5 217/542] ARM: OMAP2+: pdata-quirks: add PRM data for reset support

From: Sasha Levin <[email-masked]>
Date: Fri, 14 Feb 2020 10:43:29 -0500

From: Tero Kristo <[email-masked]>

[ Upstream commit 8de44fb70659a5bc0c53a443e6129ea1bf00fd8b ]

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.
