2017-04-13gpio: at91_gpio: remove CPU_HAS_PIO3 macroWenyou Yang
The intention of the removal is the preparation to introduce the new AT91 PIO pinctrl driver. Use the union to make the PIO3 and PIO2's registers be together and make their offset aligned. Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2016-06-12gpio: at91: Fix pullup/pulldown configuration on PIO3Marek Vasut
On systems with PIO3 (SAMA5D3/D4/..), the pullup and pulldown configuration is mutualy exclusive. This patch assures that the opposite pull resistor gets disabled before the requested pull resistor is enabled. This changes behavior of at91_set_pio_pulldown() such that the pullup is only disabled if pulldown is to be enabled. This changes behavior of at91_set_pio_pullup() such that the pulldown is only disabled if pullup is to be enabled.

2015-04-16dm: core: Add dev_get_uclass_priv() to access uclass private dataSimon Glass
Add a convenience function to access the private data that a uclass stores for each of its devices. Convert over most existing uses for consistency and to provide an example for others. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-02-12gpio: at91: Fix getting address of private dataAxel Lin
Use dev_get_priv() rather than dev_get_platdata() to get correct address of private data. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Simon Glass <sjg@chromium.org>
2014-11-21dm: at91: Add driver model support for atmel GPIO driverSimon Glass

2014-05-27gpio: at91: add sanity check for the NULL pointerWu, Josh
We need check the NULL pointer as at91_pio_get_port() may return NULL. Also print a error message when at91_pio_get_port() failed otherwise we cannot notice the failure. Signed-off-by: Josh Wu <josh.wu@atmel.com> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
