wifi: rt2x00: add nvmem eeprom support

2025-10-30T07:39:18+00:00

Some embedded platforms have eeproms located in flash. Add nvmem support to handle this. Support is added for PCI and SOC backends. Signed-off-by: Rosen Penev Link: https://patch.msgid.link/20251027180639.3797-1-rosenp@gmail.com Signed-off-by: Johannes Berg

wifi: rt2x00: check retval for of_get_mac_address

2025-10-27T08:16:12+00:00

of_get_mac_address can return -EPROBE_DEFER when nvmem is not probed yet for whatever reason. In this case, nvmem mac assignments will not work. Based on the function path, this change only has effect for rt2800soc.c and rt2800pci.c. The former tends to use nvmem for assignments.

wifi: mac80211: support parsing S1G TIM PVB

2025-09-04T09:19:01+00:00

An S1G TIM PVB has 3 mandatory encoding modes, that being block bitmap, single AID and OBL alongside the ability for each encoding mode to be inverted. Introduce the ability to parse the 3 encoding formats. The implementation specification for the encoding formats can be found in IEEE80211-2024 9.4.2.5.

wifi: rt2800: move 2x00soc to 2800soc

2025-07-23T10:29:08+00:00

This driver was written with multiple SOC platforms in mind. However since Ralink was aquired by Mediatek, it only effectively got used by older platforms. As such, we can slim down the driver slightly by moving all of rt2x00soc to rt2800soc in order to benefit from inlining.

wifi: rt2800soc: allow loading from OF

2025-07-23T10:29:08+00:00

Add a single binding to help the already present dts files load the driver. More are possible but there doesn't seem to be a significant difference between them to justify this. Use wifi name per dtschema requirements. Added OF dependency to SOC CONFIG as adding of_match_table without OF being present makes no sense.
