2017-11-14qcacmn: Clarify usage on Q_TARGET_ACCESS_BEGIN/ENDYun Park
Document where register writes are for legacy vs srng devices. With the target access begin/end calls being associated with the register writes and the register writes being associated to specific HW, we avoid performing unneeded force wakes on common code paths shared by legacy & srng based hardware. Change-Id: Id91399d03298bfc5df56f0c5d5d14b648b665279 CRs-Fixed: 2117144

2017-11-07qcacmn: Free sdio hif device when hif_device_inserted failsbings
hif_device_inserted may be failed when installing sdio wlan module, which causes memory leak. To fix this memory leak, free the hif_sdio_dev and its related DMA buffers when sdio driver fails in hif_device_inserted. Change-Id: I6ee53cd2a55fbb1492c66caa260ba8b3681526e6 CRs-Fixed: 2131539
2017-11-05qcacmn: Check target address boundary before accessSurabhi Vishnoi
Athdiag procfs entry does not have address sanity check, this is resulting in invalid ioread32/iowrite32 if out of PCIE BAR address is used. Fix this by allowing address with in PCIE BAR range. Change-Id: I8365eacca7ccc4f489b7d0bda6c998384d0fec7b CRs-Fixed: 2112270
2017-11-01qcacmn: Set the initial wake flag on MSI resumeDustin Brown
When the wlan driver is suspending, the last thing it does is check to see if the firmware has indicated a wakeup during the suspend process. This is done by checking the initial wakeup flag, which is set when a specific copy engine payload is received from firmware. For the new dedicated wake MSI, only the wake signal is received, no payload. When the wake MSI is toggled, set the initial wakeup flag to prevent race conditions during the suspend process. Change-Id: Id53cc7884431a437136d8dca068449bc5a25b87c CRs-Fixed: 2133469

2017-10-27qcacmn: Release the spin lock before returnSravan Kumar Kairam
Currently in interrupt handler of per CE, spin lock is taken for send or receive and returns with out releasing the lock held if target register access is not allowed. This condition will lead to kernel panic if some other context is trying for the same lock. Change-Id: I115f6fbb006d28097168342aa4add3526ad3939d CRs-Fixed: 2077464
2017-10-26qcacmn: Get rid of spinlock lro_unloading_lockManjunathappa Prakash
Spinlock "lro_unloading_lock" was required to synchronize the LRO instance being deleted when there is LRO packet inflight. With LRO moved to qdf and LRO is tied to hif_napi, LRO instance is active with life time of the driver. So no need to protect via lock.

2017-10-26qcacmn: Free sdio global variables scn, ol_sc in hif_sdio_closebings
When BMI failed in sdio, hif_sdio_dev->claimed_ctx is not set as valid value. Then scn, ol_sc can't be freed through hif_disable_bus as usual. To fix this memory leak, free scn, ol_sc in hif_sdio_close. Change-Id: I96b9b7c86ea6e84a32eec1c57c27ef042673e2e1 CRs-Fixed: 2131452

2017-10-12qcacmn: Do not allow CE register access when recovery is in progressGovind Singh
Currently, Shadow registers is not implemented for all registers. This can lead to unclocked access and followed by NOC errors. In Rx path Interrupt Status and src/dst read index are directly accessed without shadow block. Target may execute reset sequence due to PDR/SSR while rx path is active. Avoid direct access to below registers if target is crashed due to PDR/SSR. HOST_IE_ADDRESS HOST_IS_ADDRESS CURRENT_DRRI_ADDRESS CURRENT_SRRI_ADDRESS Return from ISR without scheduling the bottom half if target is crashed due to PDR/SSR.

2017-10-05qcacmn: Return proper error status from modules under hif_startNachiket Kukade
Some of the HIF API's that do buffer allocations and operations return either 0 or 1 as return status. Information is lost since the same value is returned in case of buffer allocation failures, queue operation failure or anything else. Caller can't decide if to perform recovery, graceful failure or BUG_ON. Return the appropriate error status to the callers. Change-Id: Idccd3968231d030311fa5581aed78849b729227d CRs-Fixed: 2105913

2017-10-01qcacmn: At set DMA mask skip IPA version checkSravan Kumar Kairam
Currently while setting DMA mask based on IPA HW version DMA address bit mask is set. So when IPA is disabled at HW wrong DMA bit mask is set which leads to allocation failures. In this change skip IPA version check if IPA HW support is absent. Change-Id: I8e438ea012ca889f9d38f22b64207b2a9532a99b CRs-Fixed: 2067774
