This adds basic SPI nodes to the base rk3288 device tree file. A few notes: * It's assumed that most users of the SPI ports are using chip select 0. Thus the default pinctrl for the ports enables chip select 0 (but not chip select 1 on ports that have it). If a board wants to use chip select 1 or wants a GPIO chip select the board should override the pinctrl (just like boards can override UART pinctrl if they have hardware flow control). * Since SPI DMA support appears broken and the SPI works fine without DMA we don't include the DMA references. That can come in a later change. Signed-off-by: huang lin <hl@rock-chips.com> Signed-off-by: Doug Anderson <dianders@chromium.org> Signed-off-by: Heiko Stuebner <heiko@sntech.de> |
