* drivers: gpio: omap: add support for parsing additional gpio parametersMugunthan V N2015-10-22-0/+11
| | | | | | | | | | | | | With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be parsed in xlate gpio drivers-ops. Since xlate is not implemented in omap_gpio driver, the driver considers all gpio to be ACTIVE_HIGH which is the default case and fails to return actual gpio status for ACTIVE_LOW gpios. So adding .xlate ops to omap_gpio. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* gpio: omap: Drop 'method' parameterTom Rini2015-08-12-48/+59
| | | | | | | | | | The "method" parameter was part of the original port of the driver from the kernel. At some point this may have been added to allow for future differentiation (as omap1 and omap2 have different GPIO IP blocks, so this wasn't an unreasonable thing to do). At this point however it's just extra overhead, so drop. Signed-off-by: Tom Rini <trini@konsulko.com>
* 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: omap3: Drop request()/free() in the driverSimon Glass2014-10-23-115/+1
| | | | | | | 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: omap: gpio: Support driver modelSimon Glass2014-10-23-0/+221
| | | | | | | | | | | | Add driver model support to this driver, while retaining support for the legacy system. Driver model GPIO support is enabled with CONFIG_DM_GPIO as usual. Since gpio_is_valid() no longer exists, we can use the -EINVAL error returned from gpio_request(). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* dm: omap: gpio: Put _get_gpio_value() logic into its own functionSimon Glass2014-10-23-36/+42
| | | | | | | | | | | | Add a separate internal helper function to get a GPIO value, so that we will be able to call it with the driver model version and avoid code duplication. Also move gpio_get_bank() and check_gpio() down below the helper functions as these won't be needed with driver model.

| | | | | | | | | | | | | | | | | Unlike the other patches in this series so far, this commit fixes a ambiguity in the license terms for some OMAP files: the code was originally derived from the Linux kernel sources, where it was clearly marked as GPL-2.0 (i. e. without the "or later" part), but the U-Boot version had a GPL-2.0+ file header added, apparently without permission / relicensing from the original authors of the code. Insert a GPL-2.0 SPDX-License-Identifier to fix this.

* ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5Axel Lin2013-07-02-1/+1
| | | | | | | | | | | | | | | | The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs. These SoCs have different gpio count but currently omap_gpio driver uses hard coded 192 which is wrong. This patch fixes this issue by: 1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h. 2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5. Thanks for Lubomir Popov to provide valuable comments to fix this issue.
