Remove the 'clocks' property to better describe the device and avoid errors when checking the dts against the nxp,lpc3220-rtc binding. Signed-off-by: Javier Carrasco --- This patch used to belong to a series that converted the affected RTC into dtschema[1] (effectively moving it to trivial-rtc), and dropped the signal clock as it uses a fixed 32768 Hz crystal. The rest of that series was merged, but I did not get any feedback for this one. I sent a little reminder ~2 months later that might have gone unnoticed too, and as a few more months passed since then, I opted for a resend with the single pending patch. It is of course not urgent, but still relevant.
