Subject: [PATCH] [POWERPC] cpm_uart: OF-related updates
Date: Mon, 11 Dec 2006 20:27:08 +0300 [thread overview]
Message-ID: <20061211172708.17475.180.stgit@localhost.localdomain> (raw)
This makes cpm uart able to work using OF-passed parameters
in case of CPM1 stuff (found on most mpc8xx reference and custom
boards).
