| Subject: ARM: dts: pxa: fix the rtc controller |
| |
| From: Robert Jarzmik <robert.jarzmik@free.fr> |
| |
| [ Upstream commit 24a610eba32a80ed778ea79680b600c3fe73d7de ] |
| |
| The RTC controller is fed by an external fixed 32kHz clock. Yet the |
| driver wants to acquire this clock, even though it doesn't make any use |
| of it, ie. doesn't get the rate to make calculation. |
| |
| Therefore, use the exported 32.768kHz clock in the PXA clock tree to |
| make the driver happy and working. |
