net: dsa: microchip: replace unclear KSZ8830 strings

2024-09-06T07:41:35Z

Replace ksz8830 with ksz88x3 for CHIP_ID definition and other strings. This due to KSZ8830 not being an actual switch but the Chip ID shared among KSZ8863/8873 switches, impossible to differentiate from their Chip ID or Revision ID registers. Now all KSZ*_CHIP_ID macros refer to actual, existing switches which removes confusion. Signed-off-by: Pieter Van Trappen Acked-by: Arun Ramadoss Signed-off-by: David S. Miller

net: dsa: microchip: rename ksz8 series files

2024-09-06T07:41:35Z

The first KSZ8 series implementation was done for a KSZ8795 device but since several other KSZ8 devices have been added. Rename these files to adhere to the ksz8 naming convention as already used in most functions and the existing ksz8.h; add an explanatory note.

KSZ8895/KSZ8864 is a switch family between KSZ8863/73 and KSZ8795, so it shares some registers and functions in those switches already implemented in the KSZ DSA driver. Signed-off-by: Tristram Ha Tested-by: Pieter Van Trappen Reviewed-by: Oleksij Rempel Signed-off-by: Jakub Kicinski

net: dsa: microchip: fix PTP config failure when using multiple ports

2024-08-20T22:53:56Z

When performing the port_hwtstamp_set operation, ptp_schedule_worker() will be called if hardware timestamoing is enabled on any of the ports. When using multiple ports for PTP, port_hwtstamp_set is executed for each port. When called for the first time ptp_schedule_worker() returns 0. On subsequent calls it returns 1, indicating the worker is already scheduled. Currently the ksz driver treats 1 as an error and fails to complete the port_hwtstamp_set operation, thus leaving the timestamping configuration for those ports unchanged. This patch fixes this by ignoring the ptp_schedule_worker() return value.

net: dsa: microchip: fix KSZ87xx family structure wrt the datasheet

2024-08-16T17:25:02Z

The KSZ87xx switches have 32 static MAC address table entries and not 8. This fixes -ENOSPC non-critical errors from ksz8_add_sta_mac when configured as a bridge. Add a new ksz87xx_dev_ops structure to be able to use the ksz_r_mib_stat64 pointer for this family; this corrects a wrong mib->counters cast to ksz88xx_stats_raw. This fixes iproute2 statistics. Rename ksz8_dev_ops structure to ksz88x3_dev_ops, in line with ksz_is_* naming conventions from ksz_common.h.

net: dsa: microchip: add WoL support for KSZ87xx family

2024-08-16T17:25:02Z

Add WoL support for KSZ87xx family of switches. This code was tested with a KSZ8794 chip. Implement ksz_common usage of the new device-tree property 'microchip,pme-active-high'. Make use of the now generalized ksz_common WoL functions, adding an additional interrupt register write for KSZ87xx. Add helper functions to convert from PME (port) read/writes to indirect register read/writes in the dedicated ksz8795 sources. Add initial configuration during (port) setup as per KSZ9477.
