2026-01-21wifi: iwlwifi: mld: Remove wrong channel flags in scan cmdDaniel Gabay
Erroneously, the channel flags in the scan command for 6 GHz scan were mistakenly set using iwl_mld_scan_get_cmd_gen_flags, which actually calculates a different field (the general flags) in the command. However, these flags are not relevant for 6 GHz scan part, except for IWL_SCAN_CHANNEL_FLAG_6G_PSC_NO_FILTER, which is already set correctly. Since the incorrect flags are only applied in the 6 GHz scan part and are ignored by the firmware, this has no adverse effect. Therefore, we can simply remove this helper function call and explicitly clear the flags.

Remove <linux/hex.h> from <linux/kernel.h> and update all users/callers of hex.h interfaces to directly #include <linux/hex.h> as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of <linux/hex.h> in the entire source tree have been updated if needed (if not already #included).

QCC2072 is a PCI based device that is very much like WCN7850, the major difference is that QCC2072 has only one phy hence does not support DBS. With previous patches handling such similarity and difference, it is now ready to finally enable supporting this device.

For QCC2072 below REO status descriptors are different compared with QCN9274/WCN7850: hal_reo_get_queue_stats_status hal_reo_flush_queue_status hal_reo_flush_cache_status hal_reo_unblock_cache_status hal_reo_flush_timeout_list_status hal_reo_desc_thresh_reached_status Take hal_reo_get_queue_stats_status as an example: QCC2072: struct hal_reo_get_queue_stats_status_qcc2072 { __le32 tlv32_padding; struct hal_reo_get_queue_stats_status status; } __packed; QCN9274/WCN7850: struct hal_reo_get_queue_stats_status; Besides, QCC2072 has a 32 bits TLV header while QCN9274/WCN7850 has 64. This means that there is no difference between these 3 devices in layout of actual fields, because they all start after a 8 bytes offset QCC2072: { struct hal_tlv_hdr tlv; __le32 tlv32_padding; struct hal_reo_get_queue_stats_status status; } QCN9274/WCN7850: { struct hal_tlv_64_hdr tlv; struct hal_reo_get_queue_stats_status status; } Therefore current implementation luckily works for QCC2072 as well. However it leads to misunderstanding, which should be avoided. So add individual REO status ring handling for QCC2072.

2026-01-15wifi: ath12k: handle REO CMD ring for QCC2072Baochen Qiang
As far as REO CMD ring is concerned, there are two differences between QCC2072 and the existing chips: For the first, the TLV header of ring descriptor for QCC2072 is 32 bits while 64 bits for existing chips. For the second, QCC2072 has different hal_reo_get_queue_stats, hal_reo_flush_cache and hal_reo_update_rx_queue structures. Take hal_reo_get_queue_stats as an example: QCC2072: struct hal_reo_get_queue_stats_qcc2072 { struct hal_reo_cmd_hdr cmd; [...] __le32 rsvd0[6]; } __packed; QCN9274/WCN7850: struct hal_reo_get_queue_stats { struct hal_reo_cmd_hdr cmd; [...] __le32 rsvd0[6]; __le32 tlv64_pad; } __packed; Note there is no tlv64_pad at the end for QCC2072, but all other former fields share the same layout. These make different ring entry size, so that parameter has to be updated with respect to existing chips. This is done in the newly introduced ath12k_hal_srng_create_config_qcc2072() function, which first creates all ring configs by utilizing ath12k_hal_srng_create_config_wcn7850() and then updates the individual field. Besides, the REO command TLV encoding also need to be corrected because of the different TLV bits. This is done by introducing a 32 bit variant for each of the existing 64 bit callback. Note the hal_reo_get_queue_stats_qcc2072 structure is introduced for the purpose of calculating ring entry size. Existing hal_reo_get_queue_stats structure gets used elsewhere even for QCC2072. This is working because the only difference is the tlv64_pad field that is located at the end and not getting used, hence can be ignored.

2026-01-15wifi: ath12k: add hardware parameters for QCC2072Baochen Qiang
Add hardware parameters for QCC2072, these parameters are directly taken from WCN7850, with exceptions to hardware name, revision, firmware directory, iova_mask and RFKILL parameter set. Compared to WCN7850, QCC2072 doesn't require aligned IOVA when transmitting packets, hence iova_mask is set to zero. Besides, WCN7850 has a dedicated GPIO for RFKILL purpose, however QCC2072 has it coupled with WLAN_EN pin. For QCC2072, host is not allowed to send any RFKILL configuration info to firmware, or firmware crashes. Hence those parameters are all cleared to skip configuring command.

2026-01-15wifi: ath12k: refactor 320 MHz bandwidth support parsingBaochen Qiang
For single pdev device, 320 MHz bandwidth support is reported only in capability of WMI_HOST_HW_MODE_SINGLE mode, hence commit d4e244c85e45 ("wifi: ath12k: enable 320 MHz bandwidth for 6 GHz band in EHT PHY capability for WCN7850") relaxed the condition check in ath12k_wmi_tlv_mac_phy_caps_ext() to allow SINGLE mode getting parsed in ath12k_wmi_tlv_mac_phy_caps_ext_parse(). Since SINGLE mode is not assumed to be preferred, the function returns unconditionally after parsing 320 MHz support. This works for WCN7850 because it prefers another mode indeed, while it breaks QCC2072 since it prefers SINGLE mode. Due to the unconditional return, the subsequent EHT parsing is skipped. Consequently EHT related features are disabled. Refactor it by moving 320 MHz parsing to ath12k_wmi_tlv_mac_phy_caps_ext(), before the mode checking. This makes the code more straightforward, and work for both WCN7850 and QCC2072.

2026-01-15wifi: ath12k: fix preferred hardware mode calculationBaochen Qiang
For single pdev device like WCN7850/QCC2072, preferred_hw_mode is initialized to WMI_HOST_HW_MODE_SINGLE. Later when firmware sends supported modes to host, each mode is compared with the initial one and if the priority of the new mode is higher, update the parameter and store mode capability. For WCN7850, this does not result in issue, as one of the supported mode indeed has a higher priority. However the only available mode of QCC2072 at this stage is WMI_HOST_HW_MODE_SINGLE, which fails the comparison, hence mode capability is not stored. Subsequently driver initialization fails. Fix it by accepting a mode with the same priority.

".max_tx_ring" is an upper bounds to indexing ".tcl2wbm_rbm_map". It is initialized in, core.c, a different file than the array. This spaghetti-like relation is fragile and not obvious. Accidentally setting ".max_tx_ring" too high leads to a hard to track out-of- bounds access and memory corruption. There is a small ambiguity on the meaning of "max_tx_ring": - The highest ring, max=3 implies there are 4 rings (0, 1, 2, 3) - The highest number to use for array indexing (there are 3 rings) Clarify this dependency by moving ".max_tx_ring" adjacent to the array ".tcl2wbm_rbm_map", and name it "num_tx_rings". Use ARRAY_SIZE() instead of #defines to initialize the length field. The intent is to make the code easier to understand rather than fix an existing bug.

That causes the connection attempt to fail. Avoid unnecessary validation during association. Apply the regulatory redundant check only when the power type is IEEE80211_REG_UNSET_AP, which only occurs during core initialization.

2026-01-15wifi: ath11k: add pm quirk for Thinkpad Z13/Z16 Gen1Ross Vandegrift
Z16 Gen1 has the wakeup-from-suspend issues from [1] but was never added to the appropriate quirk list. I've tested this patch on top of 6.18.2, it fixes the issue for me on 21D4 Mark Pearson provided the other product IDs covering the second Z16 Gen1 and both Z13 Gen1 identifiers. They share the same firmware, and folks in the bugzilla report do indeed see the problem on Z13.
