2019-02-14iwlwifi: mvm: add support for 32kHz external clock indicationHaim Dreyfuss
In low power modes, the chip clock source for platform integrated devices is 32kHz. It is generated internally and supplied by a crystal oscillator. However using a 32kHz sourced from crystal oscillator has high power penalty. There is an option to get an external 32kHz clock from the platform. Past experience shows that the reliability is platform dependent, i.e. on some platforms it works good and on other it doesn’t. Working from external clock will save 0.5 mW in sleep state, from overall 1.8mW that we have today, i.e. almost 30%. Each OEM can enable or disable the use of the external 32kHz clock by setting a BIOS configuration. In case the OEM configured to use 32kHz external clock the driver will pass this indication to the FW.

2019-02-14iwlwifi: pcie: fix TX while flushingSara Sharon
When flushing TX queues no new TX should go into the system. However, in the following scenario we get TX: 1. Queues are stopped and there are packets in overflow queue 2. Station is removed and flush begins 3. Flush empties space, and reclaim path TXes SKB from overflow queue. Note that the fact the queues are stopped during the process doesn't matter - the packet will be TXed since the TX path doesn't care if TX queues are stopped or not, just if there is space in the queue, which there is, since we just freed a packet. A fix here is rather complicated, since the flow is very racy. Change code not to warn if we are TXing from overflow TX. In case there is TX from both overflow TX and TX path we will miss a warning we optimally had, but we can live with that. Make sure we don't return before overflow queue is empty, otherwise we will think queues are empty, but they will be refilled, resulting with assert.

2019-02-14iwlwifi: mvm: Fix possible NULL pointer dereferenceAvraham Stern
iwl_mvm_te_clear_data() is called for cleanup in case sending the HOT_SPOT_CMD failed. However, in case sending the command caused a fw error and restart (e.g. if the command is not supported) then the te_data pointer may no longer be valid, which leads to a NULL pointer dereference. Fix it by checking that the te_data pointer is not NULL before dereferencing it. Signed-off-by: Avraham Stern <avraham.stern@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

Add new API and TLV for the ability to send commands in the beginning and end of reset flow. The full flow of recovery is: 1. While loading FW, get address (from the TLV) of target buffer to read in case of reset 2. If an error/assert happens read the address data from step 1. 3. Reset the HW and load the FW. 4. Send the data read in step 2. 5. Add station keys 6. Send notification to FW that reset flow is done.

2019-02-14iwlwifi: dbg_ini: rewrite trigger flow and align to FW API changesShahar S Matityahu
Trigger field ignore_default was changed to override_trig. The first byte of the field indicates the driver to override existing configuration or keep the previous one The second byte of the field indicated the driver to replace the regions of the previous trigger or to append new regions to it. Change the way the active triggers are maintained to support trigger override in different apply points. Do this by making a trigger that updates at runtime by the triggers that are being used in the different apply points. In case of an assert, the driver does not reconfigure the triggers and uses the old configuration which leads to undefined behavior. Solve this by clearing the triggers in assert recovery flow.

2019-02-13dsa: mv88e6xxx: Ensure all pending interrupts are handled prior to exitJohn David Anglin
The GPIO interrupt controller on the espressobin board only supports edge interrupts. If one enables the use of hardware interrupts in the device tree for the 88E6341, it is possible to miss an edge. When this happens, the INTn pin on the Marvell switch is stuck low and no further interrupts occur. I found after adding debug statements to mv88e6xxx_g1_irq_thread_work() that there is a race in handling device interrupts (e.g. PHY link interrupts). Some interrupts are directly cleared by reading the Global 1 status register. However, the device interrupt flag, for example, is not cleared until all the unmasked SERDES and PHY ports are serviced. This is done by reading the relevant SERDES and PHY status register. The code only services interrupts whose status bit is set at the time of reading its status register. If an interrupt event occurs after its status is read and before all interrupts are serviced, then this event will not be serviced and the INTn output pin will remain low. This is not a problem with polling or level interrupts since the handler will be called again to process the event. However, it's a big problem when using level interrupts. The fix presented here is to add a loop around the code servicing switch interrupts. If any pending interrupts remain after the current set has been handled, we loop and process the new set. If there are no pending interrupts after servicing, we are sure that INTn has gone high and we will get an edge when a new event occurs. Tested on espressobin board.

2019-02-13net: phy: fix interrupt handling in non-started statesHeiner Kallweit
phylib enables interrupts before phy_start() has been called, and if we receive an interrupt in a non-started state, the interrupt handler returns IRQ_NONE. This causes problems with at least one Marvell chip as reported by Andrew. Fix this by handling interrupts the same as in phy_mac_interrupt(), basically always running the phylib state machine. It knows when it has to do something and when not. This change allows to handle interrupts gracefully even if they occur in a non-started state.
