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>
2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
2017-06-01dm: core: Update device_bind_driver_to_node() to use ofnodeSimon Glass
Adjust this function to us an ofnode instead of an offset, so it can be used with livetree. This involves updating all callers. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: Rename dev_addr..() functionsSimon Glass
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2014-10-23net: keystone_net: register eth PHYs on MDIO busKhoronzhuk, Ivan
As MDIO bus has been added we can register PHYs with it. After registration, the PHY driver will be probed according to the hardware on board. Startup PHY at the ethernet open. Use phy_startup() instead of keystone_get_link_status() when eth open, as it verifies PHY link inside and SGMII link is checked before. For K2HK evm PHY configuration at init was absent, so don't enable phy config at init for k2hk evm. Acked-by: Vitaly Andrianov <vitalya@ti.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@ti.com>

Remove unused tx_send_loop variable. Removes duplicated get_link_status() call from the keystone2_eth_send_packet(). The emac_gigabit_enable() is called at opening Ethernet and there is no need to enable it on sending each packet. So remove that call from keystone2_eth_send_packet() as well.

2014-10-23dma: keystone_nav: generalize driver usageKhoronzhuk, Ivan
The keystone_nav driver is general driver intended to be used for working with queue manager and pktdma for different IPs like NETCP, AIF, FFTC, etc. So the it's API shouldn't be named like it works only with one of them, it should be general names. The names with prefix like netcp_* rather do for drivers/net/keystone_net.c driver. So it's good to generalize this driver to be used for different IP's and delete confusion with real NETCP driver. The current netcp_* functions of keystone navigator can be used for other settings of pktdma, not only for NETCP. The API of this driver is used by the keystone_net driver to work with NETCP, so net driver also should be corrected. For convenience collect pkdma configurations in drivers/dma/keystone_nav_cfg.c.
