2020-11-17mmc: sdhci-of-arasan: Issue DLL reset explicitlyManish Narani
In the current implementation DLL reset will be issued for each ITAP and OTAP setting inside ATF, this is creating issues in some scenarios and this sequence is not inline with the TRM. To fix the issue, DLL reset should be removed from the ATF and host driver will request it explicitly. This patch update host driver to explicitly request for DLL reset before ITAP (assert DLL) and after OTAP (release DLL) settings.

2020-11-17mmc: sdhci-pci: Prefer SDR25 timing for High Speed mode for BYT-based Intel ↵Adrian Hunter
controllers A UHS setting of SDR25 can give better results for High Speed mode. This is because there is no setting corresponding to high speed. Currently SDHCI sets no value, which means zero which is also the setting for SDR12. There was an attempt to change this in sdhci.c but it caused problems for some drivers, so it was reverted and the change was made to sdhci-brcmstb in commit 2fefc7c5f7d16e ("mmc: sdhci-brcmstb: Fix incorrect switch to HS mode"). Several other drivers also do this.

2020-11-17cpufreq: scmi: Fix OPP addition failure with a dummy clock providerSudeep Holla
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.

2020-11-16drm/i915/tgl: Fix Media power gate sequence.Rodrigo Vivi
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. So, let's now merge this to the main PG setup sequence. v2: (Chris): s/BIT/REG_BIT, remove useless comment, remove useless =0, use the right gt, remove rc6 sequence doubt from commit message.

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).

If runtime of the device has error or device is in inaccessible state(or other error state), resume operation will fail. If we do not call put operation to decrease the reference, it will result in reference count leak. Moreover, this device cannot enter the idle state and always stay busy or other non-idle state later. So we fixed it by replacing it with pm_runtime_resume_and_get.

The next patch is by Alejandro Concepcion Rodriguez and changes can_restart() to use the correct function to push a skb into the networking stack from process context. Zhang Qilong's patch fixes a memory leak in the error path of the ti_hecc's probe function. A patch by me fixes mcba_usb_start_xmit() function in the mcba_usb driver, to first fill the skb and then pass it to can_put_echo_skb(). Colin Ian King's patch fixes a potential integer overflow on shift in the peak_usb driver. The next two patches target the flexcan driver, a patch by me adds the missing "req_bit" to the stop mode property comment (which was broken during net-next for v5.10). Zhang Qilong's patch fixes the failure handling of pm_runtime_get_sync(). The next seven patches target the m_can driver including the tcan4x5x spi driver glue code. Enric Balletbo i Serra's patch for the tcan4x5x Kconfig fix the REGMAP_SPI dependency handling. A patch by me for the tcan4x5x driver's probe() function adds missing error handling to for devm_regmap_init(), and in tcan4x5x_can_remove() the order of deregistration is fixed.

2020-11-16s390/dasd: fix null pointer dereference for ERP requestsStefan Haberland
When requeueing all requests on the device request queue to the blocklayer we might get to an ERP (error recovery) request that is a copy of an original CQR. Those requests do not have blocklayer request information or a pointer to the dasd_queue set. When trying to access those data it will lead to a null pointer dereference in dasd_requeue_all_requests(). Fix by checking if the request is an ERP request that can simply be ignored. The blocklayer request will be requeued by the original CQR that is on the device queue right behind the ERP request.
