usb: gadget: Properly configure the device for remote wakeup

2024-03-06T14:45:05Z

[ Upstream commit b93c2a68f3d9dc98ec30dcb342ae47c1c8d09d18 ] The wakeup bit in the bmAttributes field indicates whether the device is configured for remote wakeup. But this field should be allowed to set only if the UDC supports such wakeup mechanism. So configure this field based on UDC capability. Also inform the UDC whether the device is configured for remote wakeup by implementing a gadget op.

usb: chipidea: add workaround for chipidea PEC bug

2023-09-23T09:11:07Z

[ Upstream commit 12e6ac69cc7e7d3367599ae26a92a0f9a18bc728 ] Some NXP processors using ChipIdea USB IP have a bug when frame babble is detected. Issue description: In USB camera test, our controller is host in HS mode. In ISOC IN, when device sends data across the micro frame, it causes the babble in host controller. This will clear the PE bit. In spec, it also requires to set the PEC bit and then set the PCI bit. Without the PCI interrupt, the software does not know the PE is cleared. This will add a flag CI_HDRC_HAS_PORTSC_PEC_MISSED to some impacted platform datas. And the ehci host driver will assert PEC by SW when specific conditions are satisfied.

usb: typec: bus: verify partner exists in typec_altmode_attention

2023-09-13T07:43:04Z

commit f23643306430f86e2f413ee2b986e0773e79da31 upstream. Some usb hubs will negotiate DisplayPort Alt mode with the device but will then negotiate a data role swap after entering the alt mode. The data role swap causes the device to unregister all alt modes, however the usb hub will still send Attention messages even after failing to reregister the Alt Mode. type_altmode_attention currently does not verify whether or not a device's altmode partner exists, which results in a NULL pointer error when dereferencing the typec_altmode and typec_altmode_ops belonging to the altmode partner. Verify the presence of a device's altmode partner before sending the Attention message to the Alt Mode driver.

usb: typec: tcpci: clear the fault status bit

2023-09-06T20:27:03Z

commit 23e60c8daf5ec2ab1b731310761b668745fcf6ed upstream. According the "USB Type-C Port Controller Interface Specification v2.0" the TCPC sets the fault status register bit-7 (AllRegistersResetToDefault) once the registers have been reset to their default values. This triggers an alert(-irq) on PTN5110 devices albeit we do mask the fault-irq, which may cause a kernel hang. Fix this generically by writing a one to the corresponding bit-7.

usb: common: usb-conn-gpio: Set last role to unknown before initial detection

2023-07-19T14:21:55Z

[ Upstream commit edd60d24bd858cef165274e4cd6cab43bdc58d15 ] Currently if we bootup a device without cable connected, then usb-conn-gpio won't call set_role() since last_role is same as current role. This happens because during probe last_role gets initialised to zero. To avoid this, added a new constant in enum usb_role, last_role is set to USB_ROLE_UNKNOWN before performing initial detection. While at it, also handle default case for the usb_role switch in cdns3, intel-xhci-usb-role-switch & musb/jz4740 to avoid build warnings.

usb: usbfs: Enforce page requirements for mmap

2023-06-14T09:15:29Z

commit 0143d148d1e882fb1538dc9974c94d63961719b9 upstream. The current implementation of usbdev_mmap uses usb_alloc_coherent to allocate memory pages that will later be mapped into the user space. Meanwhile, usb_alloc_coherent employs three different methods to allocate memory, as outlined below: * If hcd->localmem_pool is non-null, it uses gen_pool_dma_alloc to allocate memory; * If DMA is not available, it uses kmalloc to allocate memory; * Otherwise, it uses dma_alloc_coherent. However, it should be noted that gen_pool_dma_alloc does not guarantee that the resulting memory will be page-aligned. Furthermore, trying to map slab pages (i.e., memory allocated by kmalloc) into the user space is not resonable and can lead to problems, such as a type confusion bug when PAGE_TABLE_CHECK=y [1]. To address these issues, this patch introduces hcd_alloc_coherent_pages, which addresses the above two problems. Specifically, hcd_alloc_coherent_pages uses gen_pool_dma_alloc_align instead of gen_pool_dma_alloc to ensure that the memory is page-aligned. To replace kmalloc, hcd_alloc_coherent_pages directly allocates pages by calling __get_free_pages.
