Subject: [PATCH] pch_uart: Add Kontron COMe-mTT10 uart clock quirk
Date: Thu, 22 Mar 2012 21:19:03 +0100 [thread overview]
Message-ID: <20120322211903.6776ab18@mail.gmx.de> (raw)
Add UART clock quirk for the Kontron COMe-mTT10 module.
The board has previously been called nanoETXexpress-TT, therefore this
is also checked.
This patch follows the patchset submitted by Darren Hart at
commit a46f5533ecfc7bbdd646d84fdab8656031a715c6.
