| Subject: spi: pl022: Specify 'num-cs' property as required in devicetree binding |
| |
| 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. |
