2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>
2016-09-24treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada1-1/+1
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

The MXS certainly does not support any sort of networking in GPIO code, remove the netdev.h header. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Tom Rini <trini@konsulko.com> Cc: Simon Glass <sjg@chromium.org> Reviewed-by: Simon Glass <sjg@chromium.org>
2016-01-07gpio: mxs: add name_to_gpio() functionMåns Rullgård1-0/+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.

2013-11-13mxs_gpio: fix the handling in gpio_direction_output()Michael Heimpold1-2/+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. Signed-off-by: Michael Heimpold <mhei@heimpold.de> Acked-by: Stefano Babic <sbabic@denx.de>
