2019-11-29ath10k: Fix HOST capability QMI incompatibilityBjorn Andersson1-0/+1
commit 7165ef890a4c44cf16db66b82fd78448f4bde6ba upstream. The introduction of 768ec4c012ac ("ath10k: update HOST capability QMI message") served the purpose of supporting the new and extended HOST capability QMI message. But while the new message adds a slew of optional members it changes the data type of the "daemon_support" member, which means that older versions of the firmware will fail to decode the incoming request message. There is no way to detect this breakage from Linux and there's no way to recover from sending the wrong message (i.e. we can't just try one format and then fallback to the other), so a quirk is introduced in DeviceTree to indicate to the driver that the firmware requires the 8bit version of this message.

2019-02-20ath10k: switch to use SPDX license identifiersKalle Valo1-12/+1
Use SPDX identifiers everywhere in ath10k. Makefile was incorrectly marked in commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"), fix that as well. Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-20ath10k: change 'unsigned long int' to 'unsigned long'Kalle Valo1-1/+1
Fixes checkpatch warnings: Prefer 'unsigned long' over 'unsigned long int' as the int is unnecessary Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-11-06ath10k: ath10k_snoc_{read,write}32() should be staticBrian Norris1-2/+0
They're provided as callbacks in ath10k_hif_ops and should be accessed that way, if needed outside of snoc.c, and anyway, they're currently unused outside snoc.c. Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-11-06ath10k: snoc: remove 'wcn3990' from generic resource handlingBrian Norris1-4/+4
ath10k_wcn3990_clk_info and ath10k_wcn3990_vreg_info are not WCN3990-specific structures. They hold generic data. So don't name them with wcn3990 specifics.

2018-11-05ath10k: add support for WCN3990 firmware crash recoverySurabhi Vishnoi1-0/+7
Whenever the WCN3990 firmware becomes unavailable, the host driver receives a FW down indication, post which all the direct hardware register access should be avoided, in order to prevent improper behavior in the host driver. Set the crash_flush flag when the host driver receives a FW_DOWN_IND via qmi, in order to stop the untimely hardware register access. Also handle the case, where we need to do core register only for the first FW_READY indication, which is when we initialize the host driver. All the subsequent FW_READY indication will be received in subsystem recovery case and we only need to do the restart work. The state of driver is maintained using flags to distinguish between first and subsequent FW_READY indication received.

2018-10-13ath10k: add QMI message handshake for wcn3990 clientGovind Singh1-0/+4
Add WCN3990 QMI client handshakes for Q6 integrated WLAN connectivity subsystem. This layer is responsible for communicating qmi control messages to wifi fw QMI service using QMI messaging protocol. Qualcomm MSM Interface(QMI) is a messaging format used to communicate between components running between remote processors with underlying transport layer based on integrated chipset(shared memory) or discrete chipset(PCI/USB/SDIO/UART).

2018-06-14ath10k: snoc: stop including pci.hBrian Norris1-1/+0
It's easier to violate abstractions and introduce bugs when snoc.h is including pci.h. Let's not do that. I'm not extremely familiar with this driver yet, but several of the shared PCI/SNOC bits seem to be related to the Copy Engine, so move them to ce.h.

2018-04-19ath10k: platform driver for WCN3990 SNOC WLAN moduleGovind Singh1-0/+76
WCN3990 is integrated 802.11ac chipset with SNOC bus interface. Add snoc layer driver registration and associated ops. WCN3990 support is not yet complete as cold-boot handshake is done using qmi(Qualcomm-MSM-Interface) and qmi client support will be added once qmi framework is available.
