wifi: ath12k: Add single wiphy support

From: Sriram R <quic_srirrama@quicinc.com> With the introduction of Multi Link Operation (MLO) support in IEEE802.11be, each EHT AP/non AP interface is capable of operating with multiple radio links. cfg80211/mac80211 expects drivers to abstract the communication between such Multi Link HW and mac80211/cfg80211 since it depends on different driver/HW implementation. Hence the single wiphy abstraction with changes in datastructures were introduced in "wifi: ath12k: Introduce hw abstraction" This patchset extends the implementation to allow combination of multiple underlying radios into a single composite hw/wiphy for registration. Since now multiple radios are represented by a single wiphy, changes are required in various mac ops that the driver supports since the driver now needs to learn on how to tunnel various mac ops properly to a specific radio. This patchset covers the basic mac80211 ops for an interface bringup and operation. Note: Monitor and hw reconfig support for Single Wiphy will be done in future patchsets. This patchset is dependent on "[0/3] wifi: ath12k: Refactor the hardware recovery procedures" --- v2: - Rebased on ToT and dependent patchset Karthikeyan Periyasamy (1): wifi: ath12k: add multiple radio support in a single MAC HW un/register Sriram R (11): wifi: ath12k: Modify add and remove chanctx ops for single wiphy support wifi: ath12k: modify ath12k mac start/stop ops for single wiphy wifi: ath12k: vdev statemachine changes for single wiphy wifi: ath12k: scan statemachine changes for single wiphy wifi: ath12k: fetch correct radio based on vdev status wifi: ath12k: Cache vdev configs before vdev create wifi: ath12k: Add additional checks for vif and sta iterators wifi: ath12k: modify regulatory support for single wiphy architecture wifi: ath12k: Modify set and get antenna mac ops for single wiphy wifi: ath12k: Modify rts threshold mac op for single wiphy wifi: ath12k: support get_survey mac op for single wiphy drivers/net/wireless/ath/ath12k/core.h | 35 +- drivers/net/wireless/ath/ath12k/hw.h | 1 + drivers/net/wireless/ath/ath12k/mac.c | 969 +++++++++++++++++++------ drivers/net/wireless/ath/ath12k/reg.c | 60 +- 4 files changed, 836 insertions(+), 229 deletions(-)
