2021-01-25wlcore: Fix command execute failure 19 for wl12xxTony Lindgren
We can currently get a "command execute failure 19" error on beacon loss if the signal is weak: wlcore: Beacon loss detected. roles:0xff wlcore: Connection loss work (role_id: 0). ... wlcore: ERROR command execute failure 19 ... WARNING: CPU: 0 PID: 1552 at drivers/net/wireless/ti/wlcore/main.c:803 ... (wl12xx_queue_recovery_work.part.0 [wlcore]) (wl12xx_cmd_role_start_sta [wlcore]) (wl1271_op_bss_info_changed [wlcore]) (ieee80211_prep_connection [mac80211]) Error 19 is defined as CMD_STATUS_WRONG_NESTING from the wlcore firmware, and seems to mean that the firmware no longer wants to see the quirk handling for WLCORE_QUIRK_START_STA_FAILS done. This quirk got added with commit 18eab430700d ("wlcore: workaround start_sta problem in wl12xx fw"), and it seems that this already got fixed in the firmware long time ago back in 2012 as wl18xx never had this quirk in place to start with. As we no longer even support firmware that early, to me it seems that it's safe to just drop WLCORE_QUIRK_START_STA_FAILS to fix the error. Looks like earlier firmware got disabled back in 2013 with commit 0e284c074ef9 ("wl12xx: increase minimum singlerole firmware version required"). If it turns out we still need WLCORE_QUIRK_START_STA_FAILS with any firmware that the driver works with, we can simply revert this patch and add extra checks for firmware version used. With this fix wlcore reconnects properly after a beacon loss.

And in wlcore_irq(), we need to take spinlock for running the completion and for the pm_wakeup_event().

2020-03-23wireless: ti: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Pull MMC updates from Ulf Hansson: "These are the updates for MMC and MEMSTICK for v5.5. Note that this also contains quite some additional changes reaching beyond both the MMC and MEMSTICK subsystems. This is primarily because of fixing an old regression for a WiFi driver based on the SDIO interface on an OMAP openpandora board MMC core: - Add CMD13 polling for MMC IOCTLS with R1B response. - Add common DT properties for clk-phase-delays for various speed modes. - Fix size overflow for mmc gp-partitions. - Re-work HW reset for SDIO cards, which also includes a re-work for Marvell's WiFi mwifiex SDIO func driver. MMC host: - jz4740: Add support for X1000 and JZ4760. - jz4740: Add support for 8-bit bus and for low power mode. - mmci: Add support for HW busy timeout for the stm32_sdmmc variant. - owl-mmc: Add driver for Actions Semi Owl SoCs SD/MMC controller. - renesas_sdhi: Add support for r8a774b1. - sdhci_am654: Add support for Command Queuing Engine for J721E. - sdhci-milbeaut: Add driver for the Milbeaut SD controller. - sdhci-of-arasan: Add support for ZynqMP tap-delays. - sdhci-of-arasan: Add support for clk-phase-delays for SD cards. - sdhci-of-arasan: Add support for Intel LGM SDXC. - sdhci-of-aspeed: Allow inversion of the internal card detect signal. - sdhci-of-esdhc: Fixup workaround for erratum A-008171 for tunings. - sdhci-of-at91: Improve support for calibration. - sdhci-pci: Add support for Intel JSL. - sdhci-pci: Add quirk for AMD SDHC Device 0x7906. - tmio: Enable support for erase/discard/trim requests. MMC/OMAP/pandora/wl1251: The TI wl1251 WiFi driver for SDIO on the OMAP openpandora board has been broken since v4.7.

2019-10-11wlcore: clean-up clearing of WL1271_FLAG_IRQ_RUNNINGTony Lindgren
We set WL1271_FLAG_IRQ_RUNNING in the beginning of wlcore_irq(), but clear it before interrupt handling is done in wlcore_irq_locked(). Let's move the clearing to the end of wlcore_irq() where it gets set, and remove the old comments about hardirq. That's no longer the case as we're using request_threaded_irq(). Note that the WL1271_FLAG_IRQ_RUNNING should never race between the interrupt handler and wlcore_runtime_resume() as because of autosuspend timeout we cannot enter idle between wlcore_irq_locked() and the end of wlcore_irq().
