2014-10-23dm: gpio: imx: Drop request()/free() in the driverSimon Glass
Now that the uclass supports gpio_request/free() there is no need for the driver to implement it too. Drop this unnecessary code. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-22dm: imx: gpio: Support driver model in MXC gpio driverSimon Glass
Add driver model support with this driver. In this case the platform data is in the driver. It would be better to put this into an SOC-specific file, but this is best attempted when more boards are moved over to use driver model.

2013-07-24mxc_gpio: Correct the GPIO handling in gpio_direction_output()Dirk Behme
Setting the direction and an output value should be done by First, set the desired output value. Then, switch to output. If this is done in the inverse order, like at the moment, there can be a glitch on the GPIO line while switching first the old output value and aftwards the new one. Fix this by inverting the order of the direction/set_value calls. Signed-off-by: Dirk Behme <dirk.behme@de.bosch.com> Acked-by: Stefano Babic <sbabic@denx.de>
2012-11-10mx6: use CONFIG_MX6 instead of CONFIG_MX6QTroy Kisky
Use CONFIG_MX6 when the particular processor variant isn't important. Reserve the use of CONFIG_MX6Q to specifically test for quad cores variant. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

The gpio api has been tested on an armadeus apf27. Signed-off-by: Philippe Reynes <tremyfr@yahoo.fr> Acked-by: Stefano Babic <sbabic@denx.de>
2012-09-01mxc: Make gpio_get_value() use PSRBenoît Thébaudeau
gpio_get_value() should use PSR like Linux, not DR, because DR does not always reflect the pin state, while PSR does. This is especially useful to detect a short circuit on a GPIO pin configured as output, or to read the level of a pin controlled by a non-GPIO IOMUX function.

2012-04-16imx: Return gpio_set_value in gpio_direction_outputVikram Narayanan
Return gpio_set_value in gpio_direction_output. Earlier it returned 0 and ignored gpio_set_value's return value. Signed-off-by: Vikram Narayanan <vikram186@gmail.com> Acked-by: Stefano Babic <sbabic@denx.de>

2012-01-09gpio: Replace ARM gpio.h with the common API in include/asm-genericJoe Hershberger
ARM boards should use the generic GPIO API This means changing gpio to unsigned type Remove the unused gpio_toggle() function which is not part of the API Comment that free should not modify pin state Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Cc: Joe Hershberger <joe.hershberger@gmail.com> fixed merge conflict in da8xx_gpio.c, tegra2_gpio.c, and extended to the new mxs_gpio.c.

2011-09-04IMX: uniform GPIO interface using GPIO frameworkStefano Babic
IMX processors has a slightly different interface to access GPIOs and do not make use of the provided GPIO framework. The patch substitutes mxc_ specific functions and make use of the API in asm/gpio.h Signed-off-by: Stefano Babic <sbabic@denx.de>

2011-04-27IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic
As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.

2010-09-29Use common function to set GPIOs for MX3 and MX5Stefano Babic
The patch adds support for setting gpios to the MX51 processor and change name to the corresponding functions for MX31. In this way, it is possible to get rid of nasty #ifdef switches related to the processor type. Signed-off-by: Stefano Babic <sbabic@denx.de>
