Subject: [PATCH v2 1/3] dt-bindings: sdhci-of-at91: new compatible string and update properties
There is a new compatible string for the SAM9X60 sdhci device. It involves
an update of the properties about the clocks stuff.
Signed-off-by: Ludovic Desroches <ludovic.desroches@...rochip.com>

Changes:
- v2: remove the extra example and fix node label
This patch conflicts with Nicolas' one: "dt-bindings: sdhci-of-at91: add
the microchip,sdcal-inverted property". Let me know which one has to be
rebased or you can handle it.
