net: dsa: microchip: rename ksz8 series files

2024-09-06T07:41:35+00:00

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.

net: dsa: microchip: add support for different DCB app configurations

2024-05-08T09:35:10+00:00

Add DCB support to configure app trust sources and default port priority. Following commands can be used for testing: dcb apptrust set dev lan1 order pcp dscp dcb app replace dev lan1 default-prio 3 Since it is not possible to configure DSCP-Prio mapping per port, this patch provide only ability to read switch global dscp-prio mapping and way to enable/disable app trust for DSCP.

net: dsa: microchip: ptp: fix up PTP dependency

2023-01-31T12:21:38+00:00

When NET_DSA_MICROCHIP_KSZ_COMMON is built-in but PTP is a loadable module, the ksz_ptp support still causes a link failure: ld.lld-16: error: undefined symbol: ptp_clock_index >>> referenced by ksz_ptp.c >>> drivers/net/dsa/microchip/ksz_ptp.o:(ksz_get_ts_info) in archive vmlinux.a This can happen if NET_DSA_MICROCHIP_KSZ8863_SMI is enabled, or even if none of the KSZ9477_I2C/KSZ_SPI/KSZ8863_SMI ones are active but only the common module is. The most straightforward way to address this is to move the dependency to NET_DSA_MICROCHIP_KSZ_PTP itself, which can now only be enabled if both PTP_1588_CLOCK support is reachable from NET_DSA_MICROCHIP_KSZ_COMMON. Alternatively, one could make NET_DSA_MICROCHIP_KSZ_COMMON a hidden Kconfig symbol and extend the PTP_1588_CLOCK_OPTIONAL dependency to NET_DSA_MICROCHIP_KSZ8863_SMI as well, but that is a little more fragile.

net: dsa: microchip: ptp: add the posix clock support

2023-01-13T08:40:40+00:00

This patch implement routines (adjfine, adjtime, gettime and settime) for manipulating the chip's PTP clock. It registers the ptp caps to posix clock register.

net: dsa: modularize DSA_TAG_PROTO_NONE

2022-11-23T04:41:45+00:00

There is no reason that I can see why the no-op tagging protocol should be registered manually, so make it a module and make all drivers which have any sort of reference to DSA_TAG_PROTO_NONE select it. Note that I don't know if ksz_get_tag_protocol() really needs this, or if it's just the logic which is poorly written. All switches seem to have their own tagging protocol, and DSA_TAG_PROTO_NONE is just a fallback that never gets used.

net: dsa: microchip: add DSA support for microchip LAN937x

2022-07-02T15:34:05+00:00

Basic DSA driver support for lan937x and the device will be configured through SPI interface. It adds the lan937x_dev_ops in ksz_common.c file and tries to reuse the functionality of ksz9477 series switch. drivers/net/dsa/microchip/ path is already part of MAINTAINERS & the new files come under this path.

net: dsa: microchip: common ksz_spi_probe for ksz switches

2022-06-24T10:31:44+00:00

As of now, there are two spi probes, one ksz8795_spi.c and other ksz9477_spi.c. This patch combines two files into single ksz_spi.c. The difference between the two are regmap config and struct ksz8. The regmap config is assigned based on the platform data. And struct ksz8 is left untouched, as it is used only ksz8795.c. It can be used for all other switches also in future.

This patch replaces the two different menuconfig for ksz9477 and ksz8795 to single ksz_common. so that it can be extended for the other switch like lan937x. And removes the export_symbols for the extern functions in the ksz_common.h. Signed-off-by: Arun Ramadoss Signed-off-by: David S. Miller
