2018-03-21ARM: dts: at91: fixes uart pinctrl, set pullup on rx, clear pullup on txPeter Rosin1-2/+2
Remove pullup on uart TX signals, they are push-pull outputs thus pullups are pointless. Add pullup on uart RX signals, they prevent the RX signals to be left floating and so consuming a useless extra amount of power in crowbarred state if nothing is connected to RX.

2014-11-03ARM: at91: at91sam9x5 dt: add usart dma definitions to dtJiri Prchal1-0/+3
This patch adds usart dma definitions to both dtsi for sam9x5 chips. Without usage of dma it's unable to catch all bytes on usart receiver.

2014-05-22ARM: at91/dt: define sam9x5 clocksBoris BREZILLON1-0/+11
Define sam9x5 clocks in sam9x5 dt files and make use of them in peripheral definitions. Signed-off-by: Boris BREZILLON <boris.brezillon@free-electrons.com> Acked-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
2013-12-02ARM: at91: add usart3 alias to dtsiNicolas Ferre1-0/+4
Alias was missing for SoC of the at91sam9x5 familly that embed USART3.

2013-10-16ARM: at91/dt: split sam9x5 peripheral definitionsBoris BREZILLON1-0/+51
This patch splits the sam9x5 peripheral definitions into: - a common base for all sam9x5 SoCs (at91sam9x5.dtsi) - several optional peripheral definitions which will be included by specific sam9x5 SoCs (at91sam9x5_'periph name'.dtsi) This provides a better representation of the real hardware (drop unneeded dt nodes) and avoids future peripheral id conflict (lcdc and isi both use peripheral id 25).
