2021-02-09serial: core: Remove BUG_ON(in_interrupt()) checkAhmed S. Darwish
The usage of in_interrupt() in drivers is phased out for various reasons. In both exported functions where BUG_ON(in_interrupt()) is invoked, there is a mutex_lock() afterwards. mutex_lock() contains a might_sleep() which will already trigger a stack trace if the target functions is called from atomic context. Remove the BUG_ON() and add a "Context: " in the kernel-doc instead. Signed-off-by: Ahmed S.

2021-02-09i2c: mux: mlxcpld: Convert driver to platform driverVadim Pasternak
Convert driver from 'i2c' to 'platform'. The motivation is to avoid I2C addressing conflict between ‘i2c-mux-cpld’ driver, providing mux selection and deselection through CPLD ‘mux control’ register, and CPLD host driver. The CPLD is I2C device and is multi-functional device performing logic for different components, like LED, ‘hwmon’, interrupt control, watchdog etcetera. For such configuration CPLD should be host I2C device, connected to the relevant I2C bus with the relevant I2C address and all others component drivers are supposed to be its children. The hierarchy in such case will be like in the below example: ls /sys/bus/i2c/devices/44-0032 i2c-mux-mlxcpld.44 leds-mlxreg.44 mlxreg-io.44 ls /sys/bus/i2c/devices/44-0032/i2c-mux-mlxcpld.44 channel-0, …, channel-X Currently this driver is not activated by any kernel driver, so this conversion doesn’t affect any user.

If MT8183 SoC support is enabled, almost all machines will use topckgen, apmixedsys, infracfg, mcucfg and subsystem clocks, so it feels wrong to require each one to select that symbols manually. Instead, enable it whenever COMMON_CLK_MT8183_* is disabled as a simplification. This would add few KB in the kernel image size but will make the life a bit easier to the users, anyway you'll need to probably enable all of them if you want to have proper support for that SoC.

2021-02-09wil6210: Add Support for Extended DMG MCS 12.1Max Chen
FW reports Tx/Rx extended MCS 12.1 to driver as "26". Driver will convert this into base MCS 7 + EXTENDED_SC_DMG flag so kernel can do the correct phy rate conversion. Also add log prints to print "12.1" instead of "26" for extended MCS.

2021-02-09carl9170: fix struct alignment conflictArnd Bergmann
Multiple structures in the carl9170 driver have alignment impossible alignment constraints that gcc warns about when building with 'make W=1': drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned] drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned] In the carl9170_cmd structure, multiple members that have an explicit alignment requirement of four bytes are added into a union with explicit byte alignment, but this in turn is part of a structure that also has four-byte alignment. In the wlan.h header, multiple structures contain a ieee80211_hdr member that is required to be two-byte aligned to avoid alignmnet faults when processing network headers, but all members are forced to be byte-aligned using the __packed tag at the end of the struct definition. In both cases, leaving out the packing does not change the internal layout of the structure but changes the alignment constraint of the structure itself. Change all affected structures to only apply packing where it does not violate the alignment requirement of the contained structure.

2021-02-09ath11k: Update tx descriptor search index properlyKarthikeyan Periyasamy
Tx descriptor search index field should be updated with hw peer id and not by AST Hash as per the HW/FW recommendation. Incorrect search index causes throughput degradation in all scenario for all the platforms. so updated the search index field with hw peer id, which is a common change applicable for all the platforms. Also no need of these configuration for non station type. seen 10% throughput increase in WDS traffic with this change.
