Add function qe_clock_source() which takes a string containing the name of a
QE clock source (as is typically found in device trees) and returns the
matching enum qe_clock value.
Update booting-without-of.txt to indicate that the UCC properties rx-clock
and tx-clock are deprecated and replaced with rx-clock-name and tx-clock-name,
which use strings instead of numbers to indicate QE clock sources.
Update qe_setbrg() to take an enum qe_clock instead of an integer as its
first paramter.

* [PATCH 2/2] ucc_geth: use rx-clock-name and tx-clock-name device tree properties

This patch 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.
The device trees for 832x, 836x, and 8568 have been updated to contain the
new property names only.

* [PATCH 2/2] ucc_geth: use rx-clock-name and tx-clock-name device tree properties
2007-10-10 22:37 ` [PATCH 1/2] qe: add function qe_clock_source Timur Tabi

To: galak, linuxppc-dev, netdev; +Cc: Timur Tabi
This patch 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.
The device trees for 832x, 836x, and 8568 have been updated to contain the
new property names only.

This patch applies to Kumar's for-2.6.24 branch, on top of my other patch titled
"qe: add function qe_clock_source".
