2019-01-22wlcore: sdio: Fixup power on/off sequenceUlf Hansson1-8/+7
During "wlan-up", we are programming the FW into the WiFi-chip. However, re-programming the FW doesn't work, unless a power cycle of the WiFi-chip is made in-between the programmings. To conform to this requirement and to fix the regression in a simple way, let's start by allowing that the SDIO card (WiFi-chip) may stay powered on (runtime resumed) when wl12xx_sdio_power_off() returns. The intent with the current code is to treat this scenario as an error, but unfortunate this doesn't work as expected, so let's fix this. The other part is to guarantee that a power cycle of the SDIO card has been completed when wl12xx_sdio_power_on() returns, as to allow the FW programming to succeed. However, relying solely on runtime PM to deal with this isn't sufficient. For example, userspace may prevent runtime suspend via sysfs for the device that represents the SDIO card, leading to that the mmc core also keeps it powered on. For this reason, let's instead do a brute force power cycle in wl12xx_sdio_power_on().

2019-01-10ath9k: Avoid OF no-EEPROM quirks without qca,no-eepromDaniel F. Dickinson1-3/+3
ath9k_of_init() function[0] was initially written on the assumption that if someone had an explicit ath9k OF node that "there must be something wrong, why would someone add an OF node if everything is fine"[1] (Quoting Martin Blumenstingl <[email protected]>) "it turns out it's not that simple. with your requirements I'm now aware of two use-cases where the current code in ath9k_of_init() doesn't work without modifications"[1] The "your requirements" Martin speaks of is the result of the fact that I have a device (PowerCloud Systems CR5000) has some kind of default - not unique mac address - set and requires to set the correct MAC address via mac-address devicetree property, however: "some cards come with a physical EEPROM chip [or OTP] so "qca,no-eeprom" should not be set (your use-case). in this case AH_USE_EEPROM should be set (which is the default when there is no OF node)"[1] The other use case is: the firmware on some PowerMac G5 seems to add a OF node for the ath9k card automatically. depending on the EEPROM on the card AH_NO_EEP_SWAP should be unset (which is the default when there is no OF node). see [3] After this patch to ath9k_of_init() the new behavior will be: if there's no OF node then everything is the same as before if there's an empty OF node then ath9k will use the hardware EEPROM (before ath9k would fail to initialize because no EEPROM data was provided by userspace) if there's an OF node with only a MAC address then ath9k will use the MAC address and the hardware EEPROM (see the case above) with "qca,no-eeprom" EEPROM data from userspace will be requested. the behavior here will not change [1] Martin provides additional background on EEPROM swapping[1].

2019-01-10brcmfmac: Use firmware_request_nowarn for the clm_blobHans de Goede1-1/+1
The linux-firmware brcmfmac firmware files contain an embedded table with per country allowed channels and strength info. For recent hardware these versions of the firmware are specially build for linux-firmware, the firmware files directly available from Cypress rely on a separate clm_blob file for this info. For some unknown reason Cypress refuses to provide the standard firmware files + clm_blob files it uses elsewhere for inclusion into linux-firmware, instead relying on these special builds with the clm_blob info embedded. This means that the linux-firmware firmware versions often lag behind, but I digress. The brcmfmac driver does support the separate clm_blob file and always tries to load this. Currently we use request_firmware for this. This means that on any standard install, using the standard combo of linux-kernel + linux-firmware, we will get a warning: "Direct firmware load for ... failed with error -2" On top of this, brcmfmac itself prints: "no clm_blob available (err=-2), device may have limited channels available". This commit switches to firmware_request_nowarn, fixing almost any brcmfmac device logging the warning (it leaves the brcmfmac info message in place).
