   4 Subject: [PATCH 2/2] spi: ath79: set number of chipselect lines
   5
   6 All chipsets from AR7100 up to QCA9563 have three dedicated chipselect
   7 lines for the integrated SPI controller. Remove the number of
   8 chipselects from the platform data, as there is no need to manually set
   9 this to a different value.
