2020-07-23xhci: dbc: Don't use generic xhci context allocation for dbcMathias Nyman1-3/+30
The DbC context is different from the xhci device context. It's a lot smaller as it only contains three 64 bytes sub-contexts; the info, endpoint-out, and endpoint-in contexts. In total 192 bytes. The context size (CSZ) field in HCCPARAMS1 xhci register does not alter DbC context size like it does for xhci device contexts. So don't use the geneic xhci context memory allocation, or the dma pool that is intended for xhci device contexts. In addition to saving memory this also helps decoupleing xhci and dbc code.

2020-07-23xhci: dbc: Use dbc structure in the request completion instead of xhci_hcdMathias Nyman3-26/+23
The dbc request completion callback doesn't need a xhci_hcd pointer. The only user of the xhci_hcd pointer in dbgtty request callback was the xhci_warn() function. Change it to dev_warn() instead. While changing the callback function parameter to dbc in struct xhci_requeset, move the struct xhci_request declaraion down a bit in the header file to avoid compiler warinings No functional changes This change helps decoupling xhci and DbC Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20200723144530.9992-18-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-07-23xhci: dbc: Use dev_info() and similar instead of xhci_info()Mathias Nyman1-21/+21
To make this change possible we also need to change dbc_handle_port_status() to take dbc pointer as parameter instead of xhci_hcd pointer. Note that xhci_info() used xhci_to_hcd(xhci)->self.controller as the device while for dev_info we use xhci_to_hcd(xhci)->self.sysdev. In many cases those are the same, but not for some device where a dwc3 controller creates a xhci platform device. In th this case self.controller may be the platform device while self.sysdev is the actual device known to firmware (dwc3).

2020-07-23xhci: dbc: Add device pointer to dbc structureMathias Nyman2-0/+2
Currently the dbc structure contains a pointer to struct xhci_hcd, and dbc functions use that to dig up the underlying device pointer. We are trying to decouple xhci and dbc code, and prepare for code that use dbc such as dbctty into into real device drivers. This is one step along the way. Keep functionality the same and keep the xhci pointer, and let the new device pointer point to the xhci device for now.

2020-07-23xhci: Make debug message consistent with bus and port numberKai-Heng Feng1-18/+23
Current xhci debug message doesn't always output bus number, so it's hard to figure out it's from USB2 or USB3 root hub. In addition to that, some port numbers are offset to 0 and others are offset to 1. Use the latter to match the USB core. So use "bus number - port index + 1" to make debug message consistent.

2020-07-21usb: ohci-omap: Convert to use GPIO descriptorsLinus Walleij1-27/+32
The OMAP1 OHCI driver is using the legacy GPIO API to grab some random GPIO lines. One is from the TPS65010 chip and used for power, another one is for overcurrent and while the driver picks this line it doesn't watch it at all. Convert the driver and the OMAP1 OSK board file to pass these two GPIOs as machine described GPIO descriptors. I noticed the overcurrent GPIO line is not really used in the code so dropped in a little comment for other developers.

When pmc_usb_mux_set() is invoked when a device is disconnected, a valid scenario is for state->alt == NULL and state->mode == TYPEC_STATE_USB. In such cases, if a pmc_usb_disconnect() has already been issued (from either pmc_usb_set_orientation() when orientation == TYPEC_ORIENTATION_NONE, or pmc_usb_set_role() when role == USB_ROLE_NONE), a pmc_usb_connect() will be issued despite no peripheral being present. This confuses the PMC and leads to all subsequent PMC IPC requests returning errors due to timeout. To prevent this, return early if the port orientation or role is already set to none.

The core code stores a pointer to it which can lead to a use after free or double free. This used to "work" because the pointer was not stored when the initial code was written, but at some point later it was required to store it. Of course nobody noticed that the existing users break that way. - Handle affinity setting on inactive interrupts correctly when hierarchical irq domains are enabled. When interrupts are inactive with the modern hierarchical irqdomain design, the interrupt chips are not necessarily in a state where affinity changes can be handled. The legacy irq chip design allowed this because interrupts are immediately fully initialized at allocation time. X86 has a hacky workaround for this, but other implementations do not. This cased malfunction on GIC-V3. Instead of playing whack a mole to find all affected drivers, change the core code to store the requested affinity setting and then establish it when the interrupt is allocated, which makes the X86 hack go away" * tag 'irq-urgent-2020-07-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/affinity: Handle affinity setting on inactive interrupts correctly irqdomain/treewide: Keep firmware node unconditionally allocated

2020-07-18hwmon: (drivetemp) Avoid SCT usage on Toshiba DT01ACA family drivesMaciej S. Szmigiero1-0/+43
It has been observed that Toshiba DT01ACA family drives have WRITE FPDMA QUEUED command timeouts and sometimes just freeze until power-cycled under heavy write loads when their temperature is getting polled in SCT mode. The SMART mode seems to be fine, though. Let's make sure we don't use SCT mode for these drives then. While only the 3 TB model was actually caught exhibiting the problem let's play safe here to avoid data corruption and extend the ban to the whole family.

2020-07-17drivers/perf: Prevent forced unbinding of PMU driversQi Liu13-0/+13
Forcefully unbinding PMU drivers during perf sampling will lead to a kernel panic, because the perf upper-layer framework call a NULL pointer in this situation. To solve this issue, "suppress_bind_attrs" should be set to true, so that bind/unbind can be disabled via sysfs and prevent unbinding PMU drivers during perf sampling.
