Add clocks to the IPs already described in the pxa device-tree files. There are more clocks in the clock tree than IPs described in the current pxa device-tree. This patch ensures that : - the current description is correct - the clocks are actually claimed, so that clock framework doesn't disable them automatically (unused clocks shutdown) Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> --- arch/arm/boot/dts/pxa27x.dtsi | 31 ++++++++++++++++++++++++++++--- 1 file changed, 28 insertions(+), 3 deletions(-)
