4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar>

commit ea6055c46eda1e19e02209814955e13f334bbe1b upstream.

Since commit 39a6ac11df65 ("spi/pl022: Devicetree support w/o platform data")
the 'num-cs' parameter cannot be passed through platform data when probing
with devicetree. Instead, it's a required devicetree property.

Fix the binding documentation so the property is properly specified.

   The gpios will be referred to as reg = <index> in the SPI child nodes.
   If unspecified, a single SPI device without a chip select can be used.
