I think that having all WiFi-related firmware under athNk makes sense. For example wlanmdsp.mbn files are also stored under ath10k/WCN3990/ subdirs.

I think we should keep the ath11k/WCN6750/hw1.0/wpss.mdt symlink, that's fine. I was talking about adding the qcom/qcm6490/wpss.mbn -> ath11k/WCN6750/hw1.0/wpss.mbn and the same for qcs6490 (just for the sake of existing DT files) or it's fine to fix the DT files instead and omit the symlink. > > But I'd prefer Doug's ack on that. > > > --- > > > > The following changes since commit 4a0367b33aeaa7fe1255a920d0e39f825b6985c1: > > > > Merge branch 'rtl8852b' into 'main' (2024-09-11 11:00:41 +0000) > > > > are available in the Git repository at: > > > > https://gitlab.com/lumag/linux-firmware rb3gen2-wpss > > > > for you to fetch changes up to fb8c67987c89b6f33fb787dfc6ff6e5e0f317f6d: > > > > ath11k: add device-specific firmware for QCM6490 boards (2024-09-12 11:58:57 +0300) > > > > ---------------------------------------------------------------- > > Dmitry Baryshkov (2): > > ath11k: move WCN6750 firmware to the device-specific subdir > > ath11k: add device-specific firmware for QCM6490 boards > > > > WHENCE | 18 ++++++++---------- > > ath11k/WCN6750/hw1.0/qcm6490/wpss.mbn | Bin 0 -> 7734064 bytes > > qcm or qcs? qcm6490 as the main location, qcs6490 is symlinked via WHENCE file. > > Regards, > Bjorn > > > ath11k/WCN6750/hw1.0/{wpss.b04 => sc7280/wpss.mbn} | Bin 5819999 -> 7463728 bytes > > ath11k/WCN6750/hw1.0/wpss.b00 | Bin 340 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b01 | Bin 6848 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b02 | Bin 10300 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b03 | Bin 4096 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b05 | Bin 164332 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b06 | Bin 266684 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b07 | Bin 1176368 -> 0 bytes > > ath11k/WCN6750/hw1.0/wpss.b08 | 0 > > ath11k/WCN6750/hw1.0/wpss.mdt | Bin 7188 -> 0 bytes > > 12 files changed, 8 insertions(+), 10 deletions(-) > > create mode 100644 ath11k/WCN6750/hw1.0/qcm6490/wpss.mbn > > rename ath11k/WCN6750/hw1.0/{wpss.b04 => sc7280/wpss.mbn} (77%) > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b00 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b01 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b02 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b03 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b05 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b06 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b07 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.b08 > > delete mode 100644 ath11k/WCN6750/hw1.0/wpss.mdt -- With best wishes Dmitry
