Subject: [PATCH 2/2] spi: ath79: set number of chipselect lines
|
||
|
|
|
||
|
|
All chipsets from AR7100 up to QCA9563 have three dedicated chipselect
|
||
|
|
lines for the integrated SPI controller. Remove the number of
|
||
|
|
chipselects from the platform data, as there is no need to manually set
|
||
|
|
this to a different value.
