* imx: mxc_gpio: add support for imx7d SoCAdrian Alonso2015-09-02-3/+5
| | | | | | | | * Add mxc_gpio support for imx7d SoC * Use CONFIG_MX7 to extend mxc gpio driver support for imx7d Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Signed-off-by: Adrian Alonso <aalonso@freescale.com>
* of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada2015-08-18-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

* dm: core: Add dev_get_uclass_priv() to access uclass private dataSimon Glass2015-04-16-1/+1
| | | | | | | | 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>
* dm:gpio:mxc add DT supportPeng Fan2015-02-12-17/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch add DT support for mxc gpio driver. There are one place using CONFIG_OF_CONTROL macro. 1. The U_BOOT_DEVICES and mxc_plat array are complied out. To DT, platdata is alloced using calloc, so there is no need to use mxc_plat. The following situations are tested, and all work fine: 1. with DM, without DT 2. with DM and DT 3. without DM Since device tree has not been upstreamed, if want to test this patch. The followings need to be done. + pieces of code does not gpio_request when using gpio_direction_xxx and etc, need to request gpio. + move the gpio settings from board_early_init_f to board_init + define CONFIG_DM ,CONFIG_DM_GPIO and CONFIG_OF_CONTROL + Add device tree file and do related configuration in `make ARCH=arm menuconfig` These will be done in future patches by step.

| | | | | | | | | | | Add a new entry in platdata structure and intialize bank_index in mxc_plat array. This new entry can avoid using `plat - mxc_plat` by using `plat->bank_index`.

* dm: gpio: imx: Drop request()/free() in the driverSimon Glass2014-10-23-116/+0
| | | | | | | 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>
* dm: imx: gpio: Support driver model in MXC gpio driverSimon Glass2014-10-22-1/+303
| | | | | | | | | | 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.

* | mxc_gpio: Correct the GPIO handling in gpio_direction_output()Dirk Behme2013-07-24-2/+2
|/ | | | | | | | | | | | | | | | | | 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>

* mxc: Make gpio_get_value() use PSRBenoît Thébaudeau2012-09-01-1/+1
| | | | | | | | | | | 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.

* IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic2011-04-27-5/+0
| | | | | | | | | | 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.
