* generic: b53: rename exported symbols to avoid upstream conflictRobert Marko2023-06-02
| | | | | | | | | | | Upstream DSA driver is exporting symbols with the same name as our downstream swconfig driver, so lets rename the downstream symbols to make them unique and avoid the conflict on 6.1 kernel. Without this change, building 6.1 with kmod-switch-bcm53xx would conflict with the B53 DSA driver and CI would fail. Signed-off-by: Robert Marko <robimarko@gmail.com>
* Revert "swconfig: fix Broadcom b53 support"Rafał Miłecki2021-10-07
| | | | | | | | | | | | | | | | | | | | This reverts commit 8f9cd1af0f9c325a902dbd0e79e12015372e6bb0. That commit was meant to add a single EXPORT_SYMBOL_GPL() but it actually also added few .of_match_table-s. One commit should handle one thing and should not introduce unrelated changes. Regarding actual changes: 1. EXPORT_SYMBOL_GPL is not required as we don't build swconfig drivers as modules. 2. PHY drivers must not have .of_match_table. That is allowed for MDIO drivers. This could work for some time (although is didn't for me on bcm53xx) but does not with kernel 5.10. It causes a soft lockup and upstream developers confirmed it's an unsupported design.

* kernel: b53: update the BCM5365 UIDDaniel González Cabanelas2021-02-26
| | | | | | | | | | | | | | BCM63XX internal PHYs and BCM5365 SoC internal switch are both using the same phy_driver->phy_id, causing conflicts and unnecessary probes. E.g the BCM63XX phy internal IRQ is lost on the first probe. The full BCM5365 UID is 0x00406370. Use an additional byte to mask the BCM5365 UID to avoid duplicate driver phy_id's. This will fix the IRQ issue in internal BCM63XX PHYs and avoid more conflicts in the future. Signed-off-by: Daniel González Cabanelas <dgcbueu@gmail.com>
* target: remove obsolete kernel version switches for 4.19Adrian Schmutzler2020-10-30
| | | | | | | This removes unneeded kernel version switches from the targets after kernel 4.19 has been dropped. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* swconfig: fix Broadcom b53 supportTobias Schramm2020-01-12
| | | | | | | | | This commit fixes a bug in the main swconfig patch where a function needed by the b53 driver is not exported. Additionally it adds OF support to the b53_mdio driver for devicetree- based probing Signed-off-by: Tobias Schramm <tobleminer@gmail.com>
* kernel: b53: add support for kernels 5.0+Rafał Miłecki2019-04-04
| | | | | | | | It adjusts b53 code to upstream changes from the commit 3c1bcc8614db ("net: ethernet: Convert phydev advertize and supported from u32 to link mode"). Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
* kernel: b53: register switch on probeDavid Bauer2018-11-23
| | | | | | | | | | | | | Currently, the b53 MDIO switch driver registers the switch on config-init and not on device probe. Because of this, the switch gets added every time the associated interface comes up. This commit fixes this behavior by registering the switch on device probe. Compile- and run-tested on OCEDO Koala.

* kernel: b53: support phy ids for BCM5365Jonas Gorski2013-09-05
| | | | | | | | | | | | BCM5365 (and probably other older variants) use a different phy id, so the phy driver never attached for them. Fix this by adding the appropriate phy id to the fixup and the phy driver. Reported-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 37906
* generic: b53: fix reverted error check in probeJonas Gorski2013-02-10
| | | | | | | | | | | | b53_switch_detect returns value returned by b53_read8, which is 0 for success. So fail (and return error) only if b53_switch_detect returned something else than 0. This fixes supported and advertising being zeros for MDIO access. Cc: Jonas Gorski <jogo@openwrt.org> Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 35534
* generic: add b53 swconfig switch driverJonas Gorski2013-01-23
Add swconfig switch driver for Broadcom BCM53XX switch chips. Supports switches connected through MDIO, SPI or memory mapped registers, and supports BCM5325, BCM539x, BCM531x5 and the BCM63XX internal switch chips. Tested are BCM5325 trough MDIO, BCM53115 through SPI, and BCM6328. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 35305
