2022-09-28usb: xhci-mtk: fix issue of out-of-bounds array accessChunfeng Yun1-4/+6
commit de5107f473190538a65aac7edea85209cd5c1a8f upstream. Bus bandwidth array access is based on esit, increase one will cause out-of-bounds issue; for example, when esit is XHCI_MTK_MAX_ESIT, will overstep boundary.

[ Upstream commit d5dcc33677d7415c5f23b3c052f9e80cbab9ea4e ] The TRB_SMM flag indicates that DMA has completed the TD service with this TRB. Usually it’s a last TRB in TD. In case of ISOC transfer for bInterval > 1 each ISOC transfer contains more than one TD associated with usb request (one TD per ITP). In such case the TRB_SMM flag will be set in every TD and driver will recognize the end of transfer after processing the first TD with TRB_SMM. In result driver stops updating request->actual and returns incorrect actual length. To fix this issue driver additionally must check TRB_CHAIN which is not used for isochronous transfers.

2022-09-28usb: xhci-mtk: relax TT periodic bandwidth allocationIkjoon Jang1-7/+13
[ Upstream commit 548011957d1d72e0b662300c8b32b81d593b796e ] Currently xhci-mtk needs software-managed bandwidth allocation for periodic endpoints, it allocates the microframe index for the first start-split packet for each endpoint. As this index allocation logic should avoid the conflicts with other full/low-speed periodic endpoints, it uses the worst case byte budgets on high-speed bus bandwidth For example, for an isochronos IN endpoint with 192 bytes budget, it will consume the whole 4 u-frames(188 * 4) while the actual full-speed bus budget should be just 192bytes. This patch changes the low/full-speed bandwidth allocation logic to use "approximate" best case budget for lower speed bandwidth management. For the same endpoint from the above example, the approximate best case budget is now reduced to (188 * 2) bytes. Without this patch, many usb audio headsets with 3 interfaces (audio input, audio output, and HID) cannot be configured on xhci-mtk.

Two complete-split transactions are only required when the transaction spans a microframe boundary."

[ Upstream commit 8f8034f493b5eb1ad21ff392fd30c0cf9e71f73f ] If the GEVNTCOUNT indicates events in the event buffer, the driver needs to acknowledge them before the controller can halt. Simply let the interrupt handler acknowledges the remaining event generated by the controller while polling for DSTS.DEVCTLHLT. This avoids disabling irq and taking care of race condition between the interrupt handlers and pullup().

[ Upstream commit 1b1b672cc1d4fb3065dac79efb8901bd6244ef69 ] This adds the necessary ACPI ID for Intel Meteor Lake IOM devices. The callback function is_memory() is modified so that it also checks if the resource descriptor passed to it is a memory type "Address Space Resource Descriptor". On Intel Meteor Lake the ACPI memory resource is not described using the "32-bit Memory Range Descriptor" because the memory is outside of the 32-bit address space. The memory resource is described using the "Address Space Resource Descriptor" instead. Intel Meteor Lake is the first platform to describe the memory resource for this device with Address Space Resource Descriptor, but it most likely will not be the last. Therefore the change to the is_memory() callback function is made generic.

commit a872ab303d5ddd4c965f9cd868677781a33ce35a upstream. The Qualcomm dwc3 runtime-PM implementation checks the xhci platform-device pointer in the wakeup-interrupt handler to determine whether the controller is in host mode and if so triggers a resume. After a role switch in OTG mode the xhci platform-device would have been freed and the next wakeup from runtime suspend would access the freed memory. Note that role switching is executed from a freezable workqueue, which guarantees that the pointer is stable during suspend. Also note that runtime PM has been broken since commit 2664deb09306 ("usb: dwc3: qcom: Honor wakeup enabled/disabled state"), which incidentally also prevents this issue from being triggered.

commit 9d4dc16ec71bd6368548e9743223e449b4377fc7 upstream. During cdrom emulation, the response to read_toc command must contain the cdrom address as the number of sectors (2048 byte sized blocks) represented either as an absolute value (when MSF bit is '0') or in terms of PMin/PSec/PFrame (when MSF bit is set to '1'). Incase of cdrom, the fsg_lun_open call sets the sector size to 2048 bytes. When MAC OS sends a read_toc request with MSF set to '1', the store_cdrom_address assumes that the address being provided is the LUN size represented in 512 byte sized blocks instead of 2048. It tries to modify the address further to convert it to 2048 byte sized blocks and store it in MSF format. This results in data transfer failures as the cdrom address being provided in the read_toc response is incorrect.

That is, as the rtl8712 driver was being unbound from a composite device in preparation for an unrelated USB reset (that driver does not have pre_reset or post_reset callbacks), its ->remove routine called usb_reset_device() -- thus nesting one reset call within another. Performing a reset as part of disconnect processing is a questionable practice at best. However, the bug report points out that the USB core does not have any protection against nested resets. Adding a reset_in_progress flag and testing it will prevent such errors in the future.

In my case (Amlogic SoC) the warning is: phy phy-fe03e000.phy.2: phy_power_on was called before phy_init So change the order of the two calls.

2022-09-08usb: typec: altmodes/displayport: correct pin assignment for UFP receptaclesPablo Sun1-2/+2
commit c1e5c2f0cb8a22ec2e14af92afc7006491bebabb upstream. Fix incorrect pin assignment values when connecting to a monitor with Type-C receptacle instead of a plug. According to specification, an UFP_D receptacle's pin assignment should came from the UFP_D pin assignments field (bit 23:16), while an UFP_D plug's assignments are described in the DFP_D pin assignments (bit 15:8) during Mode Discovery. For example the LG 27 UL850-W is a monitor with Type-C receptacle. The monitor responds to MODE DISCOVERY command with following DisplayPort Capability flag: dp->alt->vdo=0x140045 The existing logic only take cares of UPF_D plug case, and would take the bit 15:8 for this 0x140045 case. This results in an non-existing pin assignment 0x0 in dp_altmode_configure. To fix this problem a new set of macros are introduced to take plug/receptacle differences into consideration.

2022-09-08xhci: Add grace period after xHC start to prevent premature runtime suspend.Mathias Nyman3-2/+15
commit 33e321586e37b642ad10594b9ef25a613555cd08 upstream. After xHC controller is started, either in probe or resume, it can take a while before any of the connected usb devices are visible to the roothub due to link training. It's possible xhci driver loads, sees no acivity and suspends the host before the USB device is visible. In one testcase with a hotplugged xHC controller the host finally detected the connected USB device and generated a wake 500ms after host initial start. If hosts didn't suspend the device duringe training it probablty wouldn't take up to 500ms to detect it, but looking at specs reveal USB3 link training has a couple long timeout values, such as 120ms RxDetectQuietTimeout, and 360ms PollingLFPSTimeout. So Add a 500ms grace period that keeps polling the roothub for 500ms after start, preventing runtime suspend until USB devices are detected.

The pull-up should not be set when vbus isn't present (this is determined by the drd controller).
