2013-08-19SPDX-License-Identifier: fixing some problematic GPL-2.0 filesWolfgang Denk
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.

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 <[email protected]> Acked-by: Stefano Babic <[email protected]>

2013-07-02ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5Axel Lin
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.

2013-05-13bfin: Move gpio support for bf54x and bf60x into the generic driver folder.Sonic Zhang
The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx. A lot of machine macros are used to accomodate both code in one gpio driver. This patch split the old gpio driver and move new gpio2 support to the generic gpio driver folder. - To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's config header file. - The gpio2 driver supports bf54x, bf60x and future ADI processors, while the older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561. - All blackfin specific gpio function names are replaced by the generic gpio APIs.

2013-05-09gpio: Add support for microblaze xilinx GPIOMichal Simek
Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <[email protected]>

2012-12-06x86: gpio: Add additional GPIO banks to the ICH6 driverBill Richardson
We can generally trust the ICH to have GPIO Bank 0 (the first 32 pins) in the same place across all versions. This change adds two more banks, for up to 96 GPIOS. BUT: - Not all chipsets have the same number of GPIOs - Not all chipsets have the same number of GPIO banks - Not all chipsets put the additional banks at the same offset from GPIOBASE - There so many chipset variants that it's pretty much impossible to support them all, or even keep track of the new ones. So, although this adds suppport for the additional banks that seem to work for the particular variants of CougarPoint Mobile chipsets that we've tried, there's no chance it will support everything Intel produces. Good luck. Signed-off-by: Bill Richardson <[email protected]> Signed-off-by: Simon Glass <[email protected]>

2012-10-15Tegra20: Move some include files to arch-tegra for sharing with Tegra30Tom Warren
The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK. Signed-off-by: Tom Warren <[email protected]>

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.
