2020-06-12net: phy: micrel: ksz8061 implement errata 80000688A fixBryan O'Donoghue
Linux commit 232ba3a51cc2 ('net: phy: Micrel KSZ8061: link failure after cable connect') implements a fix for the above errata. This patch replicates that errata fix in an ksz8061 specific init routine. Signed-off-by: Bryan O'Donoghue <bod@denx.de> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

2019-12-09net: phy: micrel: make sure the factory test bit is clearedNicolas Ferre
The KSZ8081 PHY has a factory test mode which is set at the de-assertion of the reset line based on the RXER (KSZ8081RNA/RND) or TXC (KSZ8081MNX/RNB) pin. If a pull-down is missing, or if the pin has a pull-up, the factory test mode should be cleared by manually writing a 0 (according to the datasheet). Create another ksz8081_config function to handle this case.

2019-05-14net: phy: micrel: Allow KSZ8xxx and KSZ90x1 to be used togetherJames Byrne
Commit d397f7c45b0b ("net: phy: micrel: Separate KSZ9000 drivers from KSZ8000 drivers") separated the KSZ8xxx and KSZ90x1 drivers and warns that you shouldn't select both of them due to a device ID clash between the KSZ9021 and the KS8721, asserting that "it is highly unlikely for a system to contain both a KSZ8000 and a KSZ9000 PHY". Unfortunately boards like the SAMA5D3xEK do contain both types of PHY, but fortunately the Linux Micrel PHY driver provides a solution by using different PHY ID and mask values to distinguish these chips. This commit contains the following changes: - The PHY ID and mask values for the KSZ9021 and the KS8721 now match those used by the Linux driver. - The warnings about not enabling both drivers have been removed. - The description for PHY_MICREL_KSZ8XXX has been corrected (these are 10/100 PHYs, not GbE PHYs). - PHY_MICREL_KSZ9021 and PHY_MICREL_KSZ9031 no longer select PHY_GIGE since this is selected by PHY_MICREL_KSZ90X1. - All of the relevant defconfig files have been updated now that PHY_MICREL_KSZ8XXX does not default to 'Y'.

2018-07-26net: phy: Clean up includes of common.hJoe Hershberger
We want to be able to include some other system headers in phy.h but that requires us to have included common.h in the top-level first. Also, common.h includes config.h as the first thing it does, so don't include it directly.

There are a number of reasons this series broke the build but none of them depend on changes in the series, so fix up those situations ahead of applying that series.

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>

2017-08-07net: phy: micrel: Separate KSZ9000 drivers from KSZ8000 driversAlexandru Gagniuc
The KS8721BL and KSZ9021 PHYs are software-incompatible, yet they share the same ID. Drivers for bothe PHYs cannot safely coexist, so the solution was to use #ifdefs to select between the two drivers. As a result KSZ9031, which has a unique ID, is now caught in the crossfire. Unless CONFIG_PHY_MICREL_KSZ9031 is defined, the KSZ9031 will not function properly, as some essential configuration code is ifdef'd-out. To prevent such situations, move the KSZ9000 drivers to a separate file, and place them under a separate Kconfig option. While it is possible to enable both KSZ8000 and KSZ9000 drivers at the same time, the assumption is that it is highly unlikely for a system to contain both a KSZ8000 and a KSZ9000 PHY, and that only one of the drivers will be enabled at any given time.
