* rt2800: move usb specific txdone/txstatus routines to rt2800libStanislaw Gruszka2018-10-01
| | | | | | | | In order to reuse usb txdone/txstatus routines for mmio, move them to common rt2800lib.c file. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rt2x00: call sta_add/remove directly in rt2800Stanislaw Gruszka2018-05-04
| | | | | | | | Only rt2800 subdriver of rt2x00 implement sta_add() and sta_remove(), we do not need generic version of those. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* wireless: Use octal not symbolic permissionsJoe Perches2018-03-27
| | | | | | | | | | | | | | Prefer the direct use of octal for permissions. Done with checkpatch -f --types=SYMBOLIC_PERMS --fix-inplace and some typing. Miscellanea: o Whitespace neatening around these conversions. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rt2800usb: constify usb_device_idArvind Yadav2017-08-10
| | | | | | | | | usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by <linux/usb.h> work with const usb_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rt2x00: Fix MMIC CountermeasuresMichael Skeffington2017-08-08

* rt2x00: Add device ID for Epson WN7512BEPTom Gaudasinski2017-05-24
| | | | | | | | Make Epson WN7512BEP work by adding its device-id to rt2800usb. Device contains a Ralink RT3071L, registers as vendor Accton/Arcadyan. Signed-off-by: Tom Gaudasinski <tomg@records.headdesk.com.au> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rt2x00: convert rt2x00_desc_read return typeArnd Bergmann2017-05-24
| | | | | | | | | | | | | This is a semi-automated conversion to change rt2x00_desc_read to return the register contents instead of passing them by value, resulting in much better object code.

* rt2x00: change function pointers for register accessorsArnd Bergmann2017-05-24
| | | | | | | | | | This prepares the driver for changing all the 'read' register accessors to return the value instead of passing it by reference. Since a lot of them are used in callbacks, this takes care of the callbacks first, adding a couple of helpers that will be removed again one at a time.

* rt2x00: use txdone_nomatch on rt2800usbStanislaw Gruszka2017-03-08
| | | | | | | | | | | | | | | | If we do not match skb entry, provide tx status via nomatch procedure. Currently in that case we do rt2x00lib_txdone_noinfo(TXDONE_NOINFO), which actually assume that entry->skb was posted without retries and provide rate saved in skb desc as successful. Patch changed that to rate read from TX_STAT_FIFO, however still do not provide correct number of retries. On SoC/PCI devices we keep providing status via standard txdone procedure, no change in those devices, though we should thing about it.

* rt2800usb: mark tx failure on timeoutStanislaw Gruszka2017-01-17
| | | | | | | | If we do not get TX status in reasonable time, we most likely fail to send frame hence mark it as so. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rt2800: increase TX timeoutStanislaw Gruszka2017-01-17
| | | | | | | | | | | | | | When medium is busy or frames have to be resend, it takes time to send the frames and get TX status from hardware. For some really bad medium conditions it can take seconds. Patch change TX status timeout to give HW more time to provide it, however 500ms is not enough for bad conditions. In the future this timeout should be removed and replaced with proper watchdog mechanism. Increase flush timeout accordingly as well.

* rt2800usb: remove watchdogStanislaw Gruszka2017-01-17
| | | | | | | | | | | | | | On rt2800usb, if we do not get TX status from HW, we assume frames were posted and after entry->last_action timeout, we forcibly provide TX status to mac80211. So it's not possible to detect hardware TX hung based on the timeout. Additionally TXRQ_PCNT tells on number of frames in the Packet Buffer (buffer between bus interface and chip MAC subsystem), which can be non zero on normal conditions. To check HW hung we will need provide some different mechanism, for now remove watchdog as current implementation is wrong and not useful.

* ktime: Cleanup ktime_set() usageThomas Gleixner2016-12-25
| | | | | | | | | | ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.

* rt2800usb: do not wipe out USB_DMA_CFG settingsStanislaw Gruszka2016-11-23
| | | | | | | | | We should not reset USB_DMA_CFG on rt2800usb_init_registers() as this function is called indirectly from rt2800_enable_radio(). If we do so, we wipe out USB_DMA_CFG settings from rt2800usb_enable_radio(). Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
