-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.
