2013-11-13mxs_gpio: fix the handling in gpio_direction_output()Michael Heimpold
Setting the direction and an output value should be done by 1) set the desired output value, 2) switch to output. If this is done in the inverse order, there can be a glitch on the GPIO line. This patch fixes this by using the order as described above. Signed-off-by: Michael Heimpold <mhei@heimpold.de> Acked-by: Stefano Babic <sbabic@denx.de>

2012-09-01mxs: prefix register acessor macros with 'mxs' prefixOtavio Salvador
As the register accessing mode is the same for all i.MXS SoCs we ought to use 'mxs' prefix intead of 'mx28'. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
2012-03-26Renamed mx28_register to mx28_register_32 to prepare for mx28_register_8Robert Delien
This patch renames mx28_register to mx28_register_32 in order to prepare for the introduction of an 8-bit register, mx28_register_8. Signed-off-by: Robert Delien <robert@delien.nl> Acked-by: Marek Vasut <marex@denx.de> Tested-by: Marek Vasut <marex@denx.de>
2012-01-10gpio: 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.

2011-12-06M28: Fix OB1 bug in GPIO driverRobert Deliën
This patch fixes a small off-by-one bug in the GPIO driver for the mxs platform that allowed the selection gpio pins of one bank more than the SoC actually has.
