wifi: mt76: use chainmask for power delta calculation

2023-12-07T17:50:21Z

The power gain value is related to total TX path, so change the calculation to use per-phy chainmask. Signed-off-by: Allen Ye Signed-off-by: Shayne Chen Signed-off-by: Felix Fietkau

wifi: mt76: permit to use alternative cell name to eeprom NVMEM load

2023-12-07T17:50:19Z

Generilize mt76_get_of_eeprom_from_nvmem to use alternative cell name by passing the cell name as an arg and expose it. Rename it to mt76_get_of_data_from_nvmem to better reflect the now more generic usage. This is to permit driver to load additional cell, like precal cell.

wifi: mt76: make mt76_get_of_eeprom static again

2023-12-07T17:50:19Z

Since mt76_get_of_eeprom is not used by mt7915 anymore, unexport it and make it static again. Also drop offset arg as it's only supported for MTD and was always set to 0, hardcode the MTD functio instead. Signed-off-by: Christian Marangi Signed-off-by: Felix Fietkau

wifi: mt76: limit support of precal loading for mt7915 to MTD only

2023-12-07T17:50:19Z

Limit support for precal loading for mt7915 only to MTD. Passing data from DT doesn't support offset and NVMEM require a different cell name and doesn't support offset hence only MTD way is actually supported. Rename mt76_get_of_eeprom_from_mtd to mt76_get_of_data_from_mtd as it is now used for a more generic purpose and export it. Signed-off-by: Christian Marangi Signed-off-by: Felix Fietkau

wifi: mt76: fix broken precal loading from MTD for mt7915

2023-12-07T17:50:19Z

Commit 495184ac91bb ("mt76: mt7915: add support for applying pre-calibration data") was fundamentally broken and never worked. The idea (before NVMEM support) was to expand the MTD function and pass an additional offset. For normal EEPROM load the offset would always be 0. For the purpose of precal loading, an offset was passed that was internally the size of EEPROM, since precal data is right after the EEPROM. Problem is that the offset value passed is never handled and is actually overwrite by offset = be32_to_cpup(list); ret = mtd_read(mtd, offset, len, &retlen, eep); resulting in the passed offset value always ingnored. (and even passing garbage data as precal as the start of the EEPROM is getting read) Fix this by adding to the current offset value, the offset from DT to correctly read the piece of data at the requested location.

wifi: mt76: mt7921: update the channel usage when the regd domain changed

2023-09-30T18:17:18Z

The 5.9/6GHz channel license of a certain platform device has been regulated in various countries. That may be difference with standard Liunx regulatory domain settings. In this case, when .reg_notifier() called for regulatory change, mt792x chipset should update the channel usage based on clc or dts configurations. Channel would be disabled by following cases. * clc report the particular UNII-x is disabled. * dts enabled and the channel is not configured.

wifi: mt76: add support for providing eeprom in nvmem cells

2023-07-26T09:15:04Z

Add support for providing eeprom in nvmem cells by adding nvmem cell as an alternative source for mt76_get_of_eeprom(). Nvmem cells will follow standard nvmem cell definition and needs to be called 'eeprom' to be correctly identified.

wifi: mt76: split get_of_eeprom in subfunction

2023-07-26T09:15:04Z

In preparation for NVMEM support, split get_of_eeprom() in subfunction to tidy the code and facilitate the addition of alternative method to get eeprom data. No behaviour change intended. While at it also drop OF ifdef checks as OF have stubs and calling of_get_property would result in the same error returned.
