2020-09-21ath11k: Remove rproc references from common core layerGovind Singh
IPQ8074 HW uses rproc with AHB as underlying hif layer. Move rproc references from common core layer to target hif layer. Remove IS_ENABLED check for CONFIG_REMOTEPROC as it's not required anymore.

2020-08-18ath11k: ce: remove CE_COUNT() macroKalle Valo
This macro is evil as it's accesses ab variable in a hidden way. It's better for readibility to access ab->hw_params.ce_count directly. This is done in a separate patch to keep the patches simple.

2020-08-17ath11k: add board file support for PCI devicesGovind Singh
PCI devices like QCA6390 load the board file differently, add support for that and the method is chosen using bus_params variables. Add support to create board name for different targets. This board name is used to parse the board data from board-2.bin for ahb/pci based targets. As struct target_mem_chunk::vaddr was changed from 'u32' to 'u32 *' in ath11k_qmi_assign_target_mem_chunk() vaddr assignments were changed to NULL to avoid a compilation warning. IPQ8074 does not use the vaddr field for anything so that change does not affect functionality. At the moment this only supports board files with BIN type. Support for ELF type, which seems to be more popular on QCA6390 devices, needs to be added later.

2020-03-18ath11k: Perform per-msdu rx processingSriram R
As Hash based reo destination selection is configured, the decapped packets reach different reo destintion rings based on the destintaion ring selected for the computed hash (based on the 5-tuple {ip src/ip dst/src port/dst port/protocol}) by hw and as configured by driver. Hence the current implementation of amsdu list based processing after all the subframes of amsdu are received (since all msdu's for a pdev are received in same reo dest ring), is not applicable here and hence is replaced with per msdu based handling as these subframes can be received in different reo dest rings. Also, as some of the rx descriptor fields might be valid only for the first msdu (for ex. received 80211 header, encryption type, etc), it might not be useful now as we cannot sync between different subframes received in different rings. Hence do not rely on those fields and replace them with fieds valid only on per msdu descriptors. Also cache other details such as encryption type for a peer so that it can be reused when a packet is received from it.

2019-11-25ath11k: driver for Qualcomm IEEE 802.11ax devicesKalle Valo
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k uses mac80211 and supports AP, Station and Mesh modes. Even though ath11k has some similar code as with ath10k (especially the WMI layer) it was concluded to be simpler to have a "clean start" for ath11k code base and not try to share the code with ath10k. This makes maintenance easier and avoids major changes in ath10k, which would have significantly increased the risk of regressions in existing setups. Even though the driver is very similar with ath10k but there are major differences as well. The datapath is completely different. ath11k supports multiple MACs, called "soc" in the firmware interface. And there's only one WMI interface to support. Currently ath11k supports only IEEE 802.11ac mode, but patches for 802.11ax are available and they will be submitted after ath11k is accepted to upstream. The firmware images are available from ath11k-firmware repository but they will be also submitted to linux-firmware: https://github.com/kvalo/ath11k-firmware This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.
