2017-05-31ARM: dts: at91: Switch to the new NAND bindingsBoris Brezillon1-29/+13
Use the new EBI/NAND bindings to declare NAND chips and remove old NAND nodes along the way. Note that we keep using old bindings in at91rm9200.dtsi because this SoC is not supported by the EBI driver.

2016-10-20ARM: dts: at91: fixes dbgu pinctrl, set pullup on rx, clear pullup on txSylvain Rochet1-2/+2
Remove pullup on dbgu DTXD signal, it is a push-pull output thus the pullup is pointless. Add pullup on dbgu DRXD signal, it prevents the DRXD signal to be left floating and so consuming a useless extra amount of power in crowbarred state if nothing is externally connected to dbgu.

2016-07-15ARM: dts: at91: fix i2c-gpio node nameAlexandre Belloni1-2/+2
i2c-gpio doesn't need a reg property. Change the node names to i2c-gpio-x as used in other dts to remove the unit-address. Solves: Warning (unit_address_vs_reg): Node /i2c@0 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /i2c@1 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /i2c@2 has a unit name, but no reg property Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2016-07-15ARM: dts: at91: Fix USB endpoint nodesAlexandre Belloni1-7/+7

2016-07-15ARM: dts: at91: Fix ADC trigger nodesAlexandre Belloni1-8/+4
The triggers don't need a reg property, remove it when prenset. Also remove the unit-address from their name. This solves: Warning (unit_address_vs_reg): Node /ahb/apb/adc@fc034000/trigger@0 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /ahb/apb/adc@fc034000/trigger@1 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /ahb/apb/adc@fc034000/trigger@2 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /ahb/apb/adc@fc034000/trigger@3 has a unit name, but no reg property Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
2015-10-19ARM: at91/dt: use syscon for PMCAlexandre Belloni1-1/+1
The PMC is not only used to drive the clocks but also has some registers related to other functions. One of those is for example the USB gadget bias. Using a syscon allows to properly separate those functions. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
