If anyone has any objections, please let me know. ------------------ From: Ezequiel Garcia 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.
