2023-12-07wifi: mt76: permit to load precal from NVMEM cell for mt7915Christian Marangi
Permit to load precal from NVMEM cell for mt7915. The NVMEM cell must be named "precal" to be correctly loaded. NVMEM cell must already account the correct offset and be placed after the EEPROM as the function expect the data right from the start.

2023-12-07wifi: mt76: permit to use alternative cell name to eeprom NVMEM loadChristian Marangi
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.

2023-12-07wifi: mt76: make mt76_get_of_eeprom static againChristian Marangi
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.

2023-12-07wifi: mt76: limit support of precal loading for mt7915 to MTD onlyChristian Marangi
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.

2023-12-07wifi: mt76: fix broken precal loading from MTD for mt7915Christian Marangi
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.

Declaration is '.. c:function:: void ieee80211_tx_status (struct ieee80211_hw *hw, struct sk_buff *skb)'. This is because there's a function named ieee80211_tx_status() and a struct named ieee80211_tx_status. This has been discussed previously but no solution found: https://lore.kernel.org/all/20220521114629.6ee9fc06@coco.lan/ There's also a bug open for three years with no solution in sight: https://github.com/sphinx-doc/sphinx/pull/8313 So I guess we have no other solution than to a workaround this in the code, for example to rename the function to ieee80211_tx_status_skb() to avoid the name conflict. I got the idea for the name from ieee80211_tx_status_noskb() in which the skb is not provided as an argument, instead with ieee80211_tx_status_skb() the skb is provided. Compile tested only.

Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

2023-09-30wifi: mt76: mt7921: update the channel usage when the regd domain changedMing Yen Hsieh
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.

Add mt7925, a new mac80211 driver for the MediaTek Wi-Fi 7 (802.11be) device Filogic 360, which can support Station, AP, P2P, and monitor modes. Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz, or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type. mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment, whereas Wi-Fi 7 and its specific features are working in progress. They will be introduced in further patches. The driver is build tested by Intel's kernel test robot with both GCC and Clang with several architecture. Sparse reports no warnings.

2023-09-30wifi: mt76: Drop unnecessary error check for debugfs_create_dir()Jinjie Ruan
debugfs_create_dir() returns ERR_PTR and never return NULL. As Russell suggested, this patch removes the error checking for debugfs_create_dir(). This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary.
