-Subject: [PATCH 32/34] spi/ath79: avoid multiple initialization of the SPI controller
-
-Currently we are initializing the SPI controller in
-the chip select line function, and that function is
-called once for each SPI device on the bus. If a
-board has multiple SPI devices, the controller will
-be initialized multiple times.
-
-Introduce ath79_spi_{en,dis}able helper functions,
-and call those from probe/response in order to avoid
-the mutliple initialization of the controller.
