commit 2a388ff22d2cbfc5cbd628ef085bdcd3b7dc64f5 upstream.
Clock description in DT binding introduced by commit f69060c14431 ("dt-bindings: rtc: zynqmp: Add clock information") is talking about "rtc" clock name but driver is checking "rtc_clk" name instead. Because clock is optional property likely in was never handled properly by the driver.
