2022-03-27s390: cleanup timer API useYu Liao
cleanup the s390's use of the timer API - del_timer() contains timer_pending() condition - mod_timer(timer, expires) is equivalent to: del_timer(timer); timer->expires = expires; add_timer(timer); If the timer is inactive it will be activated, using add_timer() on condition !timer_pending(&private->timer) is redundant. Just cleanup, no logic change.

2022-03-27s390/vfio-ap: fix kernel doc and signature of group notifier functionsTony Krowiak
The vfio_ap device driver registers a group notifier function to handle the VFIO_GROUP_NOTIFY_SET_KVM event signalling the KVM pointer has been set or cleared. There are two helper functions invoked by the handler function: One called when the KVM pointer has been set, and the other when the pointer is cleared. The kernel doc for both of these functions contains a comment introduced by commit 0cc00c8d4050 (s390/vfio-ap: fix circular lockdep when setting/clearing crypto masks) that is no longer valid. This patch removes this comment from the kernel doc of each helper function. Commit 86956e70761b (s390/vfio-ap: replace open coded locks for VFIO_GROUP_NOTIFY_SET_KVM notification) added a parameter to the signature of the helper function that handles the event indicating the KVM pointer has been cleared. The parameter added was the KVM pointer itself. One of the function's primary purposes is to clear the KVM pointer from the ap_matrix_mdev instance in which it is stored. Since the callers of this function derive the KVM pointer passed to the function from the ap_matrix_mdev object itself, it is completely unnecessary to include this parameter in the function's signature since it can simply be retrieved from the ap_matrix_mdev object which is also passed in. This patch removes the KVM pointer from the function's signature. Signed-off-by: Tony Krowiak <akrowiak@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>

The driver currently uses a CPU family match of 17h to determine EFCH_PM_DECODEEN_WDT_TMREN register support. This family check will not support future AMD CPUs and instead will require driver updates to add support. Remove the family 17h family check and add a check for SMBus PCI revision ID 0x51 or greater. The MMIO access method has been available since at least SMBus controllers using PCI revision 0x51.

2022-03-27watchdog: imx2_wdg: Alow ping on suspendAlistair Francis
The i.MX watchdog cannot be disabled by software once it has been enabled. This means that it can't be stopped before suspend. For systems that enter low power mode this is fine, as the watchdog will be automatically stopped by hardware in low power mode. Not all i.MX platforms support low power mode in the mainline kernel. For example the i.MX7D does not enter low power mode and so will be rebooted 2 minutes after entering sleep states. This patch introduces a device tree property "fsl,ping-during-suspend" that can be used to enable ping on suspend support for these systems.

2022-03-26net: hns3: fix phy can not link up when autoneg off and resetGuangbin Huang
Currently, function hclge_mdio_read() will return 0 if during reset(the cmd state will be set to disable). If use general phy driver, the phy_state_machine() will update phy speed every second in function genphy_read_status_fixed() when PHY is set to autoneg off, no matter of link down or link up. If phy driver happens to read BMCR register during reset, phy speed will be updated to 10Mpbs as BMCR register value is 0. So it may call phy can not link up if previous speed is not 10Mpbs. To fix this problem, function hclge_mdio_read() should return -EBUSY if the cmd state is disable. So does function hclge_mdio_write().

2022-03-25net: phy: broadcom: Fix brcm_fet_config_init()Florian Fainelli
A Broadcom AC201 PHY (same entry as 5241) would be flagged by the Broadcom UniMAC MDIO controller as not completing the turn around properly since the PHY expects 65 MDC clock cycles to complete a write cycle, and the MDIO controller was only sending 64 MDC clock cycles as determined by looking at a scope shot. This would make the subsequent read fail with the UniMAC MDIO controller command field having MDIO_READ_FAIL set and we would abort the brcm_fet_config_init() function and thus not probe the PHY at all. After issuing a software reset, wait for at least 1ms which is well above the 1us reset delay advertised by the datasheet and issue a dummy read to let the PHY turn around the line properly. This read specifically ignores -EIO which would be returned by MDIO controllers checking for the line being turned around. If we have a genuine reaad failure, the next read of the interrupt status register would pick it up anyway.

2022-03-25clk: Drop the rate range on clk_put()Maxime Ripard
When clk_put() is called we don't make another clk_set_rate() call to re-evaluate the rate boundaries. This is unlike clk_set_rate_range() that evaluates the rate again each time it is called. However, clk_put() is essentially equivalent to clk_set_rate_range() since after clk_put() completes the consumer's boundaries shouldn't be enforced anymore. Let's add a call to clk_set_rate_range() in clk_put() to make sure those rate boundaries are dropped and the clock provider drivers can react. Also add a few tests to make sure this case is covered.

2022-03-25clk: test: Test clk_set_rate_range on orphan muxMaxime Ripard
A bug recently affected the Tegra30 where calling clk_set_rate_range() on a clock would make it change its rate to the minimum. This was due to the clock in question being a mux that was orphan at registration, which lead to the clk_core req_rate being 0, and the clk_set_rate_range() function then calling clk_set_rate() with req_rate, effectively making that clock running at the minimum rate allowed, even though the initial rate was within that range. Make a test suite to create a mux initially orphan, and then make sure that if our clock rate was initially within a given range, then enforcing that range won't affect it.

2022-03-25net: hns3: refine the process when PF set VF VLANJian Shen
Currently, when PF set VF VLAN, it sends notify mailbox to VF if VF alive. VF stop its traffic, and send request mailbox to PF, then PF updates VF VLAN. It's a bit complex. If VF is killed before sending request, PF will not set VF VLAN without any log. This patch refines the process, PF can set VF VLAN direclty, and then notify the VF. If VF is resetting at that time, the notify may be dropped, so VF should query it after reset finished.

2022-03-25net: hns3: fix port base vlan add fail when concurrent with resetJian Shen
Currently, Port base vlan is initiated by PF and configured to its VFs, by using command "ip link set <pf name> vf <vf id> vlan <vlan id>". When a global reset was triggered, the hardware vlan table and the soft recorded vlan information will be cleared by PF, and restored them until VFs were ready. There is a short time window between the table had been cleared and before table restored. If configured a new port base vlan tag at this moment, driver will check the soft recorded vlan information, and find there hasn't the old tag in it, which causing a warning print. Due to the port base vlan is managed by PF, so the VFs's port base vlan restoring should be handled by PF when PF was ready. This patch fixes it.

2022-03-25net: hns3: fix bug when PF set the duplicate MAC address for VFsJian Shen
If the MAC address A is configured to vport A and then vport B. The MAC address of vport A in the hardware becomes invalid. If the address of vport A is changed to MAC address B, the driver needs to delete the MAC address A of vport A. Due to the MAC address A of vport A has become invalid in the hardware entry, so "-ENOENT" is returned. In this case, the "used_umv_size" value recorded in driver is not updated. As a result, the MAC entry status of the software is inconsistent with that of the hardware. Therefore, the driver updates the umv size even if the MAC entry cannot be found. Ensure that the software and hardware status is consistent.
