Subject: [PATCH 2/2] ucc_geth: use rx-clock-name and tx-clock-name device tree properties
Date: Mon,  3 Dec 2007 15:17:59 -0600	[thread overview]
Message-ID: <1196716685975-git-send-email-timur@freescale.com> (raw)
In-Reply-To: <1196716680381-git-send-email-timur@freescale.com>

Updates the ucc_geth device driver to check the new rx-clock-name and
tx-clock-name properties first.  If present, it uses the new function
qe_clock_source() to obtain the clock source.  Otherwise, it checks the
deprecated rx-clock and tx-clock properties.

Update the device trees for 832x, 836x, and 8568 to contain the new property
names only.

Signed-off-by: Timur Tabi <timur@freescale.com>

This patch applies to Kumar's for-2.6.25 branch.  ucc_geth will compile but not
run if my other patch, "qe: add function qe_clock_source" has not also been
applied.
