* gpio: mxs: add name_to_gpio() functionMåns Rullgård2016-01-071-0/+15
| | | | | | | | | | | | Override the default name_to_gpio() function with one that accepts strings of the form bank:pin. If a colon is present in the provided name, it behaves like the default version. This lets the "gpio" command work with sane names rather than requiring the user to enter the bank/pin composite in decimal.

* mxs_gpio: fix the handling in gpio_direction_output()Michael Heimpold2013-11-131-2/+2
| | | | | | | | | | | | | | 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.

* mxs: prefix register acessor macros with 'mxs' prefixOtavio Salvador2012-09-011-8/+8
| | | | | | | 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>
* Renamed mx28_register to mx28_register_32 to prepare for mx28_register_8Robert Delien2012-03-261-8/+8
| | | | | | | | | 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>
* gpio: Replace ARM gpio.h with the common API in include/asm-genericJoe Hershberger2012-01-091-23/+19
| | | | | | | | | | | | | | | | 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.

* M28: Fix OB1 bug in GPIO driverRobert Deliën2011-12-061-1/+1
| | | | | | | | 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.
