2022-04-10net: phy: don't require PHY interface mode during PHY creationMarek Behún1-2/+2
Currently we require PHY interface mode to be known when finding/creating the PHY - the functions * phy_connect_phy_id() * phy_device_create() * create_phy_by_mask() * search_for_existing_phy() * get_phy_device_by_mask() * phy_find_by_mask() all require the interface parameter, but the only thing done with it is that it is assigned to phydev->interface. This makes it impossible to find a PHY device without overwriting the set mode. Since the interface mode is not used during .probe() and should be used at first in .config(), drop the interface parameter from these functions. Make the default value of phydev->interface (in phy_device_create()) to be PHY_INTERFACE_MODE_NA. Move the interface parameter to phy_connect_dev(), where it should be. Change all occurrences treewide. In occurrences where we don't call phy_connect_dev() for some reason (they only configure the PHY without connecting it to an ethernet controller), set phydev->interface = value from phy_find_by_mask call.

2020-12-13dm: treewide: Rename dev_get_platdata() to dev_get_plat()Simon Glass1-3/+3
Rename this to be consistent with the change from 'platdata'. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-1/+1
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-2/+2
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

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>
2017-06-02net: pch_gbe: Add cache maintenancePaul Burton1-0/+12
On MIPS systems DMA isn't coherent with the CPU caches unless an IOCU is present. When there is no IOCU we need to writeback or invalidate the data caches at appropriate points. Perform this cache maintenance in the pch_gbe driver which is used on the MIPS Boston development board.

2017-06-02net: pch_gbe: CPU accessible addresses are virtualPaul Burton1-12/+13
Use the virt_to_bus & bus_to_virt functions rather than phys_to_bus & bus_to_phys, since the addresses accessed by the CPU will be virtual rather than physical. On MIPS physical & virtual addresses differ as we use virtual addresses in kseg0, and attempting to use physical addresses directly caused problems as they're in the user segment which would be mapped via the uninitialised TLB.

2016-09-21net: pch_gbe: Make 64 bit safePaul Burton1-10/+10
The pch_gbe driver previously casted pointers to & from unsigned 32 bit integers in many locations. This breaks the driver on 64 bit systems, producing streams of compiler warnings about mismatched pointer & integer sizes and then failing to keep track of addresses correctly at runtime. Fix the driver for 64 bit systems by using unsigned longs in place of the previously used 32 bit integers.

2016-09-21net: pch_gbe: Use dm_pci_map_bar to discover MMIO basePaul Burton1-5/+3
Reading the PCI BAR & converting the result to a physical address is not safe across all architectures. For example on MIPS the virtual:physical mapping is not 1:1, so we cannot directly make use of the physical address. Use the more generic BAR-mapping function dm_pci_map_bar to discover the MMIO base address, which should work across architectures.
