| |
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.
