2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2015-05-04powerpc/mpc85xx: Fix compiling error for common/cmd_gpio.cOleksandr G Zhadan
To replicate: 1. add to include/configs/p1_p2_rdb_pc.h "#define CONFIG_CMD_GPIO" 2. run `make P1020RDB-PC_defconfig` 3. run CROSS_COMPILE=powerpc-linux- make and you will get: common/built-in.o: In function `do_gpio': u-boot/common/cmd_gpio.c:186: undefined reference to `gpio_request' u-boot/common/cmd_gpio.c:194: undefined reference to `gpio_direction_input' u-boot/common/cmd_gpio.c:195: undefined reference to `gpio_get_value' u-boot/common/cmd_gpio.c:200: undefined reference to `gpio_get_value' u-boot/common/cmd_gpio.c:203: undefined reference to `gpio_direction_output' u-boot/common/cmd_gpio.c:209: undefined reference to `gpio_free Signed-off-by: Michael Durrant <mdurrant@arcturusnetworks.com> Signed-off-by: Oleksandr G Zhadan <oleks@arcturusnetworks.com> Reviewed-by: York Sun <yorksun@freescale.com>
2013-11-25mpc85xx: Fix the offset of register address errorTang Yuantian
The offset of register address within GPIO module is just CONFIG_SYS_MPC85xx_GPIO_ADDR. So, fix it. The following platforms are confirmed: MPC8572, P1023, P1020, P1022, P2020, P4080, P5020, P5040, T4240, B4860. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com>

2012-10-22mpc85xx: make gpio_direction_output respect valueChris Packham
Users of familiar with the Linux gpiolib API expect that value parameter to gpio_direction_output reflects the initial state of the output pin. gpio_direction_output was always driving the output low, now it drives it high or low according to the value provided.

2011-10-21mpc85xx: Add inline GPIO acessor functionsKyle Moffett
To ease the implementation of other MPC85xx board ports, several common GPIO helpers are added to <asm/mpc85xx_gpio.h>. Since each of these compiles to no more than 4-5 instructions it would be very inefficient to call them out of line, therefore we put them entirely in the header file. The HWW-1U-1A board port which these were written for strongly prefers to set multiple GPIOs as a single batch operation, so the API is designed around that basis. To assist other board ports, a small set of wrappers are used which provides a standard gpio_request() interface around the MPC85xx-specific functions. This can be enabled with CONFIG_MPC85XX_GENERIC_GPIO Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Cc: Andy Fleming <afleming@gmail.com> Cc: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
