As a part of device shutdown the smmu driver will be stopped and henceforth any IOVA address translation will not be done. The wlan driver, being one of the smmu driver consumer, should stop all the dma related activity as a part of shutdown, and thereby ensuring that no dma activity is done once the smmu driver shuts down. During the device shutdown, the smmu calls shutdown for all its consumers in order to indicate them to stop all their dma activities. Register the shutdown handler to stop the wlan driver and avoid any dma operations. Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1 Signed-off-by:

For QCA6390, normal power up and power down can't bring MHI to a workable state. This happens especially in warm reboot and rmmod and insmod. Host needs to write a few registers to bring MHI to normal state.

QCA6390 doesn't enable V2 map and ummap event, so the addr search flags and type is different from IPQ8074. Assign correct search flags and type for QCA6390.

For QCA6390, only one pdev is created and this pdev manages both lmacs, thus both rxdmas. So host needs to initialize all rxdma related rings for one pdev. Another difference is for QCA6390, host fills rxbuf to firmware and firmware further fills the rxbuf to rxbuf ring for each rxdma.

For QCA6390, it has 2 lmacs and thus 2 rxdmas. However, each rxdma has rxdma0 only, and doesn't have rxdma1.

There's no reason to have call for enable_pll_clk in ath10k_bmi_start(), move it to ath10k_core_start() instead. This way it's possible to call ath10k_bmi_start() from sdio.c during firmware dump creation. And also the function call is more visible when it's in core.c.

The value of "htc_hdr->endpoint_id" comes from skb->data so Smatch marks it as untrusted so we have to check it before using it as an array offset.

The ath9k driver was so far only able to rekey PTK0 keys correctly due to the best effort queue flush added with commit 62872a9b ("mac80211: Fix PTK rekey freezes and clear text leak"). Add the needed queue flush and set NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to tell mac80211 that the driver can now rekey PTK0 keys correctly and no longer needs the best effort flush. Effectively this prevents mac80211 to warn when rekeying a PTK0 key only. Signed-off-by:

The decoded_size is wrongly assigned in ath11k_qmi_msg_handlers and it results in out of boundary access in qmi_decode. The correct decoded_size should be calculated from the related ind_msg structure. This issue is exposed with QCA6390 because it needs 11 small memory chunks which are stored in qmi_wlanfw_request_mem_ind_msg_v01 and hence the decoded_size exceeds the wrongly assigend decoded_size.
