2025-03-11net: miiphybb: Drop bb_miiphy_alloc()/bb_miiphy_free() and struct bb_miiphy_busMarek Vasut
These functions are no longer necessary, remove them. The struct bb_miiphy_bus is no longer necessary either, remove it as well. Signed-off-by: Marek Vasut <[email protected]> Reviewed-by: Paul Barker <[email protected]>
2025-03-11net: miiphybb: Pass struct mii_dev directly to bb_miiphy_read/write()Marek Vasut
Access to MDIO bus private data can be provided by both struct mii_dev .priv member and struct bb_miiphy_bus .priv member, use the former directly and remove .priv from the later. Drop unused bb_miiphy_getbus(). This removes any dependency on struct bb_miiphy_bus from the miiphybb code, except for helper functions which will be removed later.

2025-03-11net: miiphybb: Pass struct bb_miiphy_bus_ops directly to bb_miiphy_read/write()Marek Vasut
The access to struct bb_miiphy_bus_ops via ops pointer in struct bb_miiphy_bus is not necessary with wrappers added in previous patch. Pass the ops pointer directly to both bb_miiphy_read() and bb_miiphy_write() functions. Signed-off-by: Marek Vasut <[email protected]> Reviewed-by: Paul Barker <[email protected]>
2025-03-11net: miiphybb: Split off struct bb_miiphy_bus_opsMarek Vasut
Move miiphybb operations into separate struct bb_miiphy_bus_ops structure, add pointer to struct bb_miiphy_bus_ops into the base struct bb_miiphy_bus and access the ops through this pointer in miiphybb generic code. The variable reshuffling in miiphybb.c cannot be easily avoided. Signed-off-by: Marek Vasut <[email protected]> Reviewed-by: Paul Barker <[email protected]>
2025-02-26net: miiphybb: Use container_of() in bb_miiphy_getbus()Marek Vasut
Replace the name based look up in bb_miiphy_getbus() with trivial container_of() call. This works because the struct bb_miiphy_bus always embeds the matching struct mii_dev . This also makes the code much simpler and more efficient. Reviewed-by: Paul Barker <[email protected]> Signed-off-by: Marek Vasut <[email protected]>
2025-02-26net: miiphybb: Introduce bb_miiphy_alloc()/bb_miiphy_free() wrappersMarek Vasut
Introduce bb_miiphy_alloc()/bb_miiphy_free() wrappers to allocate and free struct bb_miiphy_bus. Make struct bb_miiphy_bus wrap struct mii_dev, which will become useful later in bb_miiphy_bus accessors, which would be able to access struct bb_miiphy_bus using container_of, even if the PHY stack only passes in the inner struct mii_dev .

It seems that every remaining system which enables BITBANGMII also enables BITBANGMII_MULTI . Remove the BITBANGMII_MULTI symbol and assume it is always enabled.

2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

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 <[email protected]>
2018-01-15net: miiphybb: fix casting errorChris Brandt
Since the return value is a signed int, if the leading MSB of rdreg is a 1, it will get signed extended and will return a negative value which is an error even though we read the correct value.

2010-08-09Fix compile warnings for const correctnessBen Warren
Commit 6e37b1a3a25004d3df5867de49fff6b3fc9c4f04 modifies several net calls to take a (const char *) parameter instead of (char *), but in some cases the modified functions call other functions taking (char *). The end result is warnings about discarding the const qualifier. This patch fixes these other function signatures. Signed-off-by: Ben Warren <[email protected]>

2009-10-10Rewrite the miiphybb (Bit-banged MII bus driver) in order to support an ↵Luigi 'Comio' Mantellini
arbitrary number of mii buses. This feature is useful when your board uses different mii buses for different phys and all (or a part) of these buses are implemented via bit-banging mode. The driver requires that the following macros should be defined into the board configuration file: CONFIG_BITBANGMII - Enable the miiphybb driver CONFIG_BITBANGMII_MULTI - Enable the multi bus support If the CONFIG_BITBANGMII_MULTI is not defined, the board's config file needs to define at least the following macros: MII_INIT - Generic code to enable the MII bus (optional) MDIO_DECLARE - Declaration needed to access to the MDIO pin (optional) MDIO_ACTIVE - Activate the MDIO pin as out pin MDIO_TRISTATE - Activate the MDIO pin as input/tristate pin MDIO_READ - Read the MDIO pin MDIO(v) - Write v on the MDIO pin MDC_DECLARE - Declaration needed to access to the MDC pin (optional) MDC(v) - Write v on the MDC pin The previous macros make the driver compatible with the previous version (that didn't support the multi-bus). When the CONFIG_BITBANGMII_MULTI is also defined, the board code needs to fill the bb_miiphy_buses[] array with a record for each required bus and declare the bb_miiphy_buses_num variable with the number of mii buses. The record (struct bb_miiphy_bus) has the following fields/callbacks (see miiphy.h for details): char name[] - The symbolic name that must be equal to the MII bus registered name int (*init)() - Initialization function called at startup time (just before the Ethernet initialization) int (*mdio_active)() - Activate the MDIO pin as output int (*mdio_tristate)() - Activate the MDIO pin as input/tristate pin int (*set_mdio)() - Write the MDIO pin int (*get_mdio)() - Read the MDIO pin int (*set_mdc)() - Write the MDC pin int (*delay)() - Delay function void *priv - Private data used by board specific code The board code will look like: struct bb_miiphy_bus bb_miiphy_buses[] = { { .name = miibus#1, .init = b1_init, .mdio_active = b1_mdio_active, ... }, { .name = miibus#2, .init = b2_init, .mdio_active = b2_mdio_active, ... }, ... int bb_miiphy_buses_num = sizeof(bb_miiphy_buses) / sizeof(bb_miiphy_buses[0]); Signed-off-by: Luigi 'Comio' Mantellini <[email protected]> Signed-off-by: Ben Warren <[email protected]>
2009-07-22MIIPHYBB: Return 0xFFFF if the PHY is not asserting TA.Richard Retanubun
This patch sets the returned value to 0xFFFF if the PHY does not exist and does not assert Transfer Acknowledge. A NULL check for the value pointer is also added for buffer overflow protection. Without this patch 'mii info' will show 'phantom' devices because the value will be not be initialized and return with some random value.
