2021-03-25net: dsa: lantiq_gswip: Let GSWIP automatically set the xMII clockMartin Blumenstingl
The xMII interface clock depends on the PHY interface (MII, RMII, RGMII) as well as the current link speed. Explicitly configure the GSWIP to automatically select the appropriate xMII interface clock. This fixes an issue seen by some users where ports using an external RMII or RGMII PHY were deaf (no RX or TX traffic could be seen). Most likely this is due to an "invalid" xMII clock being selected either by the bootloader or hardware-defaults.

2021-03-25net: dsa: only unset VLAN filtering when last port leaves last VLAN-aware bridgeVladimir Oltean
DSA is aware of switches with global VLAN filtering since the blamed commit, but it makes a bad decision when multiple bridges are spanning the same switch: ip link add br0 type bridge vlan_filtering 1 ip link add br1 type bridge vlan_filtering 1 ip link set swp2 master br0 ip link set swp3 master br0 ip link set swp4 master br1 ip link set swp5 master br1 ip link set swp5 nomaster ip link set swp4 nomaster [138665.939930] sja1105 spi0.1: port 3: dsa_core: VLAN filtering is a global setting [138665.947514] DSA: failed to notify DSA_NOTIFIER_BRIDGE_LEAVE When all ports leave br1, DSA blindly attempts to disable VLAN filtering on the switch, ignoring the fact that br0 still exists and is VLAN-aware too.

2021-03-25s390/vdso: fix initializing and updating of vdso_dataHeiko Carstens
Li Wang reported that clock_gettime(CLOCK_MONOTONIC_RAW, ...) returns incorrect values when time is provided via vdso instead of system call: vdso_ts_nsec = 4484351380985507, vdso_ts.tv_sec = 4484351, vdso_ts.tv_nsec = 380985507 sys_ts_nsec = 1446923235377, sys_ts.tv_sec = 1446, sys_ts.tv_nsec = 923235377 Within the s390 specific vdso function __arch_get_hw_counter() reads tod clock steering values from the arch_data member of the passed in vdso_data structure. Problem is that only for the CS_HRES_COARSE vdso_data arch_data is initialized and gets updated. The CS_RAW specific vdso_data does not contain any valid tod_clock_steering information, which explains the different values. Fix this by initializing and updating all vdso_datas.

2021-03-25s390/vdso: fix tod_steering_delta typeHeiko Carstens
The s390 specific vdso function __arch_get_hw_counter() is supposed to consider tod clock steering. If a tod clock steering event happens and the tod clock is set to a new value __arch_get_hw_counter() will not return the real tod clock value but slowly drift it from the old delta until the returned value finally matches the real tod clock value again. Unfortunately the type of tod_steering_delta unsigned while it is supposed to be signed. It depends on if tod_steering_delta is negative or positive in which direction the vdso code drifts the clock value. Worst case is now that instead of drifting the clock slowly it will jump into the opposite direction by a factor of two. Fix this by simply making tod_steering_delta signed.

2021-03-25vfio/type1: Empty batch for pfnmap pagesDaniel Jordan
When vfio_pin_pages_remote() returns with a partial batch consisting of a single VM_PFNMAP pfn, a subsequent call will unfortunately try restoring it from batch->pages, resulting in vfio mapping the wrong page and unbalancing the page refcount. Prevent the function from returning with this kind of partial batch to avoid the issue. There's no explicit check for a VM_PFNMAP pfn because it's awkward to do so, so infer it from characteristics of the batch instead. This may result in occasional false positives but keeps the code simpler.

2021-03-25Input: iqs5xx - make reset GPIO optionalJeff LaBundy
The device's hardware reset pin is only required if the platform must be able to update the device's firmware. As such, demote the reset GPIO to optional in support of devices that ship with pre-programmed firmware and don't route the reset pin back to the SoC. In that case, the 'fw_file' attribute is hidden because there is no way to open the bootloader. The logic is extended to the case in which the device does not advertise bootloader support in the first place. Last but not least, remove the hardware reset performed at probe because there is no reason to reset the device manually. A power on reset function already ensures a clean reset at start-up.

Some devices outside of drivers/input/touchscreen/ can still make use of the touchscreen helper functions. Therefore, it was agreed in [1] to move them outside of drivers/input/touchscreen/ so that other devices can call them without INPUT_TOUCHSCREEN being set. As part of this change, 'of' is dropped from the filename because the helpers no longer actually use OF. No changes are made to the file contents whatsoever.

The bootloader can be closed using the 'execute' command (0x02) or hardware reset. Rather than using the former option for successful firmware update procedures and reserving the latter for recovering the device upon failure, simply use hardware reset for all cases. The post-bootloader initialization delay increases marginally when triggered by a hardware reset, so increase the wait time to ensure the device does not subsequently fail to respond.

2021-03-25Input: gpio-keys - use hrtimer for software debounce, if possiblePaul Cercueil
We want to be able to report the input event as soon as the debounce delay elapsed. However, the current code does not really ensure that, as it uses the jiffies-based schedule_delayed_work() API. With a small enough HZ value (HZ <= 100), this results in some input events being lost, when a key is quickly pressed then released (on a human's time scale). Switching to hrtimers fixes this issue, and will work even on extremely low HZ values (tested at HZ=24). This is however only possible if reading the GPIO is possible without sleeping. If this condition is not met, the previous approach of using a jiffies-based timer is taken.

2021-03-25Input: gpio-keys - use hrtimer for release timerPaul Cercueil
Dealing with input, timing is important; if the button should be released in one millisecond, then it should be done in one millisecond and not a hundred milliseconds. Therefore, the standard timer API is not really suitable for this task. Convert the gpio-keys driver to use a hrtimer instead of the standard timer to address this issue. Note that by using a hard IRQ for the hrtimer callback, we can get rid of the spin_lock_irqsave() and spin_unlock_irqrestore().

2021-03-25Input: gpio-keys - remove extra call to input_syncPaul Cercueil
The input_sync() function is already called after the loop in gpio_keys_report_state(), so it does not need to be called after each iteration within gpio_keys_gpio_report_event().

2021-03-25gfs2: report "already frozen/thawed" errorsBob Peterson
Before this patch, gfs2's freeze function failed to report an error when the target file system was already frozen as it should (and as generic vfs function freeze_super does. Similarly, gfs2's thaw function failed to report an error when trying to thaw a file system that is not frozen, as vfs function thaw_super does. The errors were checked, but it always returned a 0 return code. This patch adds the missing error return codes to gfs2 freeze and thaw.
