[PATCH v3 0/2] add clock-names property to nand node

[niravkumar.l.rabara]

From: Niravkumar L Rabara <niravkumar.l.rabara@intel.com>

1) Document the required clock-names property because the driver
   requests the clock by name and not the index.
2) Add required clock-names property to the nand node in device tree.

Changes in v3:
  * Include missing Fixes tag.

Changes in v2:
  * Document clock-names property for Cadence NAND controller.

[PATCH v3 1/2] dt-bindings: mtd: cadence: document required clock-names

[niravkumar.l.rabara]

From: Niravkumar L Rabara <niravkumar.l.rabara@intel.com>

The clock-names property is required because the driver requests
the clock by name and not the index.
Update the example to use &clk instead of &nf_clk for the clocks
property to avoid confusion with the clock-names property "nf_clk".

The following patch has been applied to mtd/fixes:

[1/2] dt-bindings: mtd: cadence: document required clock-names
      commit: 211b841f34cce652258ddec7fa4750a748b28471

Patche(s) should be available on mtd/linux.git and will be
part of the next PR (provided that no robot complains by then).

Kind regards,
Miquèl
