2025-05-16wifi: ath12k: update regulatory rules when interface addedBaochen Qiang
There are two power types for 6 GHz regulatory, one is AP, another is client. The client power type is used for station interface, and AP power type is used for AP/mesh point interface. When firmware boots up, WMI_REG_CHAN_LIST_CC_EXT_EVENTID is sent from firmware at an early stage, the interface mode is not decided at this point, then ath12k select reg rules of AP type as default. After interface created, ath12k needs to update reg rules to the exact power type matching the interface type.

2025-05-16wifi: ath12k: store reg info for later useBaochen Qiang
Currently we only build regdomain when channel list event is received. That event is received when driver boots or when a new country code is sent to firmware. At either time we may have no information about interface mode or AP's power type, consequently WMI_REG_INDOOR_AP is selected. In upcoming patches we will rebuild regdomain once those information is available. For that purpose reg info has to be stored/refreshed each time a new channel list event is received. The stored reg info would be freed in ath12k_reg_free() when it is not needed.

2025-05-16wifi: ath12k: move reg info handling outsideBaochen Qiang
The reg info is allocated in ath12k_reg_chan_list_event() but validated in ath12k_reg_handle_chan_list(). Currently this is good since reg info would be freed regardless of validation results. However in an upcoming patch the reg info might need to be stored for later use if the result is good. Since we can not tell the result from return value of ath12k_reg_handle_chan_list(), we need to move validation out of it. Add a new helper ath12k_reg_validate_reg_info() and call it in ath12k_reg_chan_list_event(), based on the result we can choose to store or free it in the following patch.

2025-05-16wifi: ath12k: add support to select 6 GHz regulatory typeBaochen Qiang
For 6 GHz band, firmware offers 3 types of regulatory rules for AP mode and 6 for station mode in WMI_REG_CHAN_LIST_CC_EXT_EVENTID event. In ath12k_reg_build_regd() current code by default chooses WMI_REG_INDOOR_AP type rules from AP mode reg list to build regdomain, regardless of the interface mode and power type, hence is not correct. Pass interface mode (wmi_vdev_type) and AP power type (ieee80211_ap_reg_power) as new arguments to ath12k_reg_build_regd() such that we can choose correct rules based on them. Currently ath12k_reg_build_regd() is called only by ath12k_reg_chan_list_event() when driver boots, at that time these two arguments are not determined yet, hence by default pass WMI_VDEV_TYPE_UNSPEC and IEEE80211_REG_UNSET_AP, this results in WMI_REG_INDOOR_AP being chosen at last. In upcoming patches the rules would be updated when these two arguments could be determined.

2025-05-16wifi: ath12k: refactor ath12k_reg_chan_list_event()Baochen Qiang
ath12k_reg_chan_list_event() is doing quite some work: allocate/free reg_info, parse chan list event and store required info in reg_info, process reg_info, build regd and queue work item for later processing etc, which makes it hard to read. Refactor this function: 1. extract reg_info processing and regd building into a new helper ath12k_reg_handle_chan_list(). 2. extract reg_info free into a new helper ath12k_reg_reset_reg_info(). Note the refactor also benefit some upcoming patches where these helpers are getting called. Also relocate these two helpers and the existing ath12k_reg_is_world_alpha() to reg.c to reflect what they are doing. And update fw to firmware while relocating.

2025-05-16wifi: ath12k: fix a possible dead lock caused by ab->base_lockBaochen Qiang
spin_lock/spin_unlock are used in ath12k_reg_chan_list_event to acquire/release ab->base_lock. For now this is safe because that function is only called in soft IRQ context. But ath12k_reg_chan_list_event() will be called from process context in an upcoming patch, and this can result in a deadlock if ab->base_lock is acquired in process context and then soft IRQ occurs on the same CPU and tries to acquire that lock. Fix it by using spin_lock_bh and spin_unlock_bh instead.

2025-05-16irqdomain: Drop irq_domain_add_*() functionsJiri Slaby (SUSE)
Most irq_domain_add_*() functions are unused now, so drop them. The remaining ones are moved to the deprecated section and will be removed during the merge window after the patches in various trees have been merged. Note: The Chinese docs are touched but unfinished. I cannot parse those.

2025-05-16powerpc: Switch irq_domain_add_nomap() to use fwnodeJiri Slaby (SUSE)
All irq_domain_add_*() functions are going away. PowerPC is the only user of irq_domain_add_nomap() and there is no irq_domain_create_nomap() complement. Therefore, to align with the rest of the kernel, rename irq_domain_add_nomap() to irq_domain_create_nomap() and accept a fwnode_handle instead of a device_node.

2025-05-16thermal: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).
