2019-05-14mfd: axp20x: Allow the AXP223 to be probed by I2CMaxime Ripard1-0/+2
The AXP223 can be used both using the RSB proprietary bus, or a more traditional I2C bus. The RSB is a faster bus and provides more features (like some integrity checks on the messages), so it's usually preferrable to use it, but since it's proprietary, when we want to use the PMIC in a multi-master setup, the i2c might make sense as well.

2019-05-14mfd: twl6040: Fix device init errors for ACCCTL registerTony Lindgren1-1/+12
I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero: twl6040 0-004b: Failed to write 2d = 19: -121 And then any following register access will produce errors. There 2d offset above is register ACCCTL that gets written on twl6040 powerup. With error checking added to the related regcache_sync() call, the -EREMOTEIO error is reproducable on twl6040 powerup at least duovero. To fix the error, we need to wait until twl6040 is accessible after the powerup. Based on tests on omap4 duovero, we need to wait over 8ms after powerup before register write will complete without failures. Let's also make sure we warn about possible errors too. Note that we have twl6040_patch[] reg_sequence with the ACCCTL register configuration and regcache_sync() will write the new value to ACCCTL.

2019-05-02i2c: Prevent runtime suspend of adapter when Host Notify is requiredJarkko Nikula1-0/+4
Multiple users have reported their Synaptics touchpad has stopped working between v4.20.1 and v4.20.2 when using SMBus interface. The culprit for this appeared to be commit c5eb1190074c ("PCI / PM: Allow runtime PM without callback functions") that fixed the runtime PM for i2c-i801 SMBus adapter. Those Synaptics touchpad are using i2c-i801 for SMBus communication and testing showed they are able to get back working by preventing the runtime suspend of adapter. Normally when i2c-i801 SMBus adapter transmits with the client it resumes before operation and autosuspends after. However, if client requires SMBus Host Notify protocol, what those Synaptics touchpads do, then the host adapter must not go to runtime suspend since then it cannot process incoming SMBus Host Notify commands the client may send. Fix this by keeping I2C/SMBus adapter active in case client requires Host Notify.

There are two problems with dev_err() here. One: It is not ratelimited. Two: We don't see which driver tried to transfer something with a suspended adapter. Switch to dev_WARN_ONCE to fix both issues. Drawback is that we don't see if multiple drivers are trying to transfer while suspended. They need to be discovered one after the other now.

e8303bb7a75c ("PCI/LINK: Report degraded links via link bandwidth notification") added dmesg logging whenever a link changes speed or width to a state that is considered degraded. Unfortunately, it cannot differentiate signal integrity-related link changes from those intentionally initiated by an endpoint driver, including drivers that may live in userspace or VMs when making use of vfio-pci. Some GPU drivers actively manage the link state to save power, which generates a stream of messages like this: vfio-pci 0000:07:00.0: 32.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s x16 link at 0000:00:02.0 (capable of 64.000 Gb/s with 5 GT/s x16 link) Since we can't distinguish the intentional changes from the signal integrity issues, leave the reporting turned off by default. Add a Kconfig option to turn it on if desired.

2019-05-01PCI/portdrv: Use shared MSI/MSI-X vector for Bandwidth ManagementAlex Williamson1-1/+2
The Interrupt Message Number in the PCIe Capabilities register (PCIe r4.0, sec 7.5.3.2) indicates which MSI/MSI-X vector is shared by interrupts related to the PCIe Capability, including Link Bandwidth Management and Link Autonomous Bandwidth Interrupts (Link Control, 7.5.3.7), Command Completed and Hot-Plug Interrupts (Slot Control, 7.5.3.10), and the PME Interrupt (Root Control, 7.5.3.12). pcie_message_numbers() checked whether we want to enable PME or Hot-Plug interrupts but neglected to check for Link Bandwidth Management, so if we only wanted the Bandwidth Management interrupts, it decided we didn't need any vectors at all. Then pcie_port_enable_irq_vec() tried to reallocate zero vectors, which failed, resulting in fallback to INTx. On some systems, e.g., an X79-based workstation, that INTx seems broken or not handled correctly, so we got spurious IRQ16 interrupts for Bandwidth Management events. Change pcie_message_numbers() so that if we want Link Bandwidth Management interrupts, we use the shared MSI/MSI-X vector from the PCIe Capabilities register.

Revert commit c8b1917c8987 ("ACPICA: Clear status of GPEs before enabling them") that causes problems with Thunderbolt controllers to occur if a dock device is connected at init time (the xhci_hcd and thunderbolt modules crash which prevents peripherals connected through them from working). Commit c8b1917c8987 effectively causes commit ecc1165b8b74 ("ACPICA: Dispatch active GPEs at init time") to get undone, so the problem addressed by commit ecc1165b8b74 appears again as a result of it.

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers Kalle Valo says: ==================== wireless-drivers fixes for 5.1 Third set of fixes for 5.1. iwlwifi * fix an oops when creating debugfs entries * fix bug when trying to capture debugging info while in rfkill * prevent potential uninitialized memory dumps into debugging logs * fix some initialization parameters for AX210 devices * fix an oops with non-MSIX devices * fix an oops when we receive a packet with bogus lengths * fix a bug that prevented 5350 devices from working * fix a small merge damage from the previous series mwifiex * fig regression with resume on SDIO ath10k * fix locking problem with crashdump * fix warnings during suspend and resume Also note that this pull conflicts with net-next. And I want to emphasie that it's really net-next, so when you pull this to net tree it should go without conflicts. Stephen reported the conflict here: https://lkml.kernel.org/r/20190429115338.5decb50b@canb.auug.org.au In iwlwifi oddly commit 154d4899e411 adds the IS_ERR_OR_NULL() in wireless-drivers but commit c9af7528c331 removes the whole check in wireless-drivers-next. The fix is easy, just drop the whole check for mvmvif->dbgfs_dir in iwlwifi/mvm/debugfs-vif.c, it's unneeded anyway. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-04-30net: dsa: bcm_sf2: fix buffer overflow doing set_rxnfcDan Carpenter1-0/+6
The "fs->location" is a u32 that comes from the user in ethtool_set_rxnfc(). We can't pass unclamped values to test_bit() or it results in an out of bounds access beyond the end of the bitmap.

This reverts commit f4c34b1e2a37d5676180901fa6ff188bcb6371f8. Simliar to commit a0cecc23cfcb Revert "drm/virtio: drop prime import/export callbacks". We have to do the same with qxl, for the same reasons (it breaks DRI3). Drop the WARN_ON_ONCE().

The parameter to ZERO_PAGE() was wrong, but since all architectures except for MIPS and s390 ignore it, it wasn't noticed until 0-day reported the build error.
