2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass1-0/+1
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

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>
2017-06-01dm: Rename dev_addr..() functionsSimon Glass1-1/+1
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.

2017-03-26net: sunxi-emac: Write HW address via functionoliver@schinagl.nl1-4/+15
Currently the mac address is programmed directly in _sunxi_emac_eth_init making it a one time inflexible operation. By moving it into a separate function, we can now use this more flexibly. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2015-07-21dm: eth: Avoid blocking on packet receptionSimon Glass1-1/+1
Some devices can take a long time to work out whether they have a new packet or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do this, since it waits until it gets a new packet on the wire before allowing the USB bulk read packet to be submitted. At present with driver mode the Ethernet receive code reads 32 packets. This can take a very long time if we must wait for all 32 packets. The old code (before driver model) worked by reading a single set of packets from the USB device, then processing all the packets with in. It would be nice to use the same behaviour with driver model. Add a flag to the receive method which indicates that the driver should try to find a packet if available, by consulting the hardware. When the flag is not set, it should just return any packet data it has already received. If there is none, it should return -EAGAIN so that the loop will terminate.

2015-05-04sunxi: emac: Rename DMA_CPU_TRRESHOLD to EMAC_RX_BUFSIZEHans de Goede1-2/+2
Besides being spelled wrong, the DMA_CPU_TRRESHOLD define actually has nothing to do with DMA as we only use mmio fifo access. Rename it to EMAC_RX_BUFSIZE to properly reflect what it does.

2015-04-18net: cosmetic: Fix var naming net <-> eth driversJoe Hershberger1-2/+2
Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support. This patch has a few remaining checkpatch.pl failures that would be out of the scope of this patch to fix (drivers that are in gross violation of checkpatch.pl).

2015-04-15sunxi: GPIO pin mux hardware-feature-specific function index definesPaul Kocialkowski1-1/+1
Each hardware feature exposed through the GPIO pin mux is usually using the same function index (for a given port), so there is no need to define one value per pin: one value per hardware feature per port is sufficient, avoids duplication and makes everything easier to understand.

There have been 3 versions of the sunxi_emac support patch during its development. Somehow version 2 ended up in upstream u-boot where as the u-boot-sunxi git repo got version 3. This bumps the version in upstream u-boot to version 3 of the patch: - Initialize MII clock earlier so mii access to allow independent use - Name change from WEMAC to EMAC to match mainline kernel & chip manual - Cosmetic code cleanup Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Henrik Nordstrom <henrik@henriknordstrom.net> Signed-off-by: Oliver Schinagl <oliver@schinagl.nl> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
