We had a report a while back that the ads7846 driver had some issues when used with DMA-based SPI controllers (like atmel_spi) on systems where main memory is not DMA-coherent (most non-x86 boards). Allocate memory potentially used for DMA separately to avoid cache line issues. Reported-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru> |
