Commit dd461cd9183f ("opp: Allow dev_pm_opp_get_opp_table() to return -EPROBE_DEFER") handles -EPROBE_DEFER for the clock/interconnects within _allocate_opp_table() which is called from dev_pm_opp_add and it now propagates the error back to the caller. SCMI performance domain re-used clock bindings to keep it simple. However with the above mentioned change, if clock property is present in a device node, opps fails to get added with below errors until clk_get succeeds. cpu0: failed to add opp 450000000Hz cpu0: failed to add opps to the device ....(errors on cpu1-cpu4) cpu5: failed to add opp 450000000Hz cpu5: failed to add opps to the device So, in order to fix the issue, we need to register dummy clock provider. With the dummy clock provider, clk_get returns NULL(no errors!), then opp core proceeds to add OPPs for the CPUs. Cc: Rafael J.

2020-11-17cpufreq: tegra186: Fix get frequency callbackJon Hunter
Commit b89c01c96051 ("cpufreq: tegra186: Fix initial frequency") implemented the CPUFREQ 'get' callback to determine the current operating frequency for each CPU. This implementation used a simple looked up to determine the current operating frequency. The problem with this is that frequency table for different Tegra186 devices may vary and so the default boot frequency for Tegra186 device may or may not be present in the frequency table. If the default boot frequency is not present in the frequency table, this causes the function tegra186_cpufreq_get() to return 0 and in turn causes cpufreq_online() to fail which prevents CPUFREQ from working. Fix this by always calculating the CPU frequency based upon the current 'ndiv' setting for the CPU. Note that the CPU frequency for Tegra186 is calculated by reading the current 'ndiv' setting, multiplying by the CPU reference clock and dividing by a constant divisor.

2020-11-16scsi: target: iscsi: Fix cmd abort fabric stop raceMike Christie
Maurizio found a race where the abort and cmd stop paths can race as follows: 1. thread1 runs iscsit_release_commands_from_conn and sets CMD_T_FABRIC_STOP. 2. thread2 runs iscsit_aborted_task and then does __iscsit_free_cmd. It then returns from the aborted_task callout and we finish target_handle_abort and do: target_handle_abort -> transport_cmd_check_stop_to_fabric -> lio_check_stop_free -> target_put_sess_cmd The cmd is now freed. 3. thread1 now finishes iscsit_release_commands_from_conn and runs iscsit_free_cmd while accessing a command we just released. In __target_check_io_state we check for CMD_T_FABRIC_STOP and set the CMD_T_ABORTED if the driver is not cleaning up the cmd because of a session shutdown. However, iscsit_release_commands_from_conn only sets the CMD_T_FABRIC_STOP and does not check to see if the abort path has claimed completion ownership of the command. This adds a check in iscsit_release_commands_from_conn so only the abort or fabric stop path cleanup the command.

2020-11-16scsi: libiscsi: Fix NOP race conditionLee Duncan
iSCSI NOPs are sometimes "lost", mistakenly sent to the user-land iscsid daemon instead of handled in the kernel, as they should be, resulting in a message from the daemon like: iscsid: Got nop in, but kernel supports nop handling. This can occur because of the new forward- and back-locks, and the fact that an iSCSI NOP response can occur before processing of the NOP send is complete. This can result in "conn->ping_task" being NULL in iscsi_nop_out_rsp(), when the pointer is actually in the process of being set. To work around this, we add a new state to the "ping_task" pointer. In addition to NULL (not assigned) and a pointer (assigned), we add the state "being set", which is signaled with an INVALID pointer (using "-1").

2020-11-16bnxt_en: Fix counter overflow logic.Michael Chan
bnxt_add_one_ctr() adds a hardware counter to a software counter and adjusts for the hardware counter wraparound against the mask. The logic assumes that the hardware counter is always smaller than or equal to the mask. This assumption is mostly correct. But in some cases if the firmware is older and does not provide the accurate mask, the driver can use a mask that is smaller than the actual hardware mask. This can cause some extra carry bits to be added to the software counter, resulting in counters that far exceed the actual value. Fix it by masking the hardware counter with the mask passed into bnxt_add_one_ctr(). Fixes: fea6b3335527 ("bnxt_en: Accumulate all counters.")

2020-11-16net: ipa: lock when freeing transactionAlex Elder
Transactions sit on one of several lists, depending on their state (allocated, pending, complete, or polled). A spinlock protects against concurrent access when transactions are moved between these lists. Transactions are also reference counted. A newly-allocated transaction has an initial count of 1; a transaction is released in gsi_trans_free() only if its decremented reference count reaches 0. Releasing a transaction includes removing it from the polled (or if unused, allocated) list, so the spinlock is acquired when we release a transaction. The reference count is used to allow a caller to synchronously wait for a committed transaction to complete. In this case, the waiter takes an extra reference to the transaction *before* committing it (so it won't be freed), and releases its reference (calls gsi_trans_free()) when it is done with it. Similarly, gsi_channel_update() takes an extra reference to ensure a transaction isn't released before the function is done operating on it. Until the transaction is moved to the completed list (by this function) it won't be freed, so this reference is taken "safely." But in the quiesce path, we want to wait for the "last" transaction, which we find in the completed or polled list. Transactions on these lists can be freed at any time, so we (try to) prevent that by taking the reference while holding the spinlock. Currently gsi_trans_free() decrements a transaction's reference count unconditionally, acquiring the lock to remove the transaction from its list *only* when the count reaches 0. This does not protect the quiesce path, which depends on the lock to ensure its extra reference prevents release of the transaction. Fix this by only dropping the last reference to a transaction in gsi_trans_free() while holding the spinlock.

Some media power gates are disabled by default. commit 5d86923060fc ("drm/i915/tgl: Enable VD HCP/MFX sub-pipe power gating") tried to enable it, but it duplicated an existent register. So, the main PG setup sequences ended up overwriting it.

2020-11-16net: lantiq: Wait for the GPHY firmware to be readyMartin Blumenstingl
A user reports (slightly shortened from the original message): libphy: lantiq,xrx200-mdio: probed mdio_bus 1e108000.switch-mii: MDIO device at address 17 is missing. gswip 1e108000.switch lan: no phy at 2 gswip 1e108000.switch lan: failed to connect to port 2: -19 lantiq,xrx200-net 1e10b308.eth eth0: error -19 setting up slave phy This is a single-port board using the internal Fast Ethernet PHY. The user reports that switching to PHY scanning instead of configuring the PHY within device-tree works around this issue. The documentation for the standalone variant of the PHY11G (which is probably very similar to what is used inside the xRX200 SoCs but having the firmware burnt onto that standalone chip in the factory) states that the PHY needs 300ms to be ready for MDIO communication after releasing the reset. Add a 300ms delay after initializing all GPHYs to ensure that the GPHY firmware had enough time to initialize and to appear on the MDIO bus. Unfortunately there is no (known) documentation on what the minimum time to wait after releasing the reset on an internal PHY so play safe and take the one for the external variant. Only wait after the last GPHY firmware is loaded to not slow down the initialization too much ( xRX200 has two GPHYs but newer SoCs have at least three GPHYs).
