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

2023-07-19T14:21:56Z

[ Upstream commit df49f2a0ac4a34c0cb4b5c233fcfa0add644c43c ] This reverts commit edd60d24bd858cef165274e4cd6cab43bdc58d15. Heikki reports that this should not be a global flag just to work around one broken driver and should be fixed differently, so revert it.

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.

Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1. Nothing major in here, lots of little things with new devices supported and updates for a few drivers. Highlights include: - thunderbolt/USB4 devices supported a bit better than before, and some new ids to enable new hardware devices - USB gadget uvc updates for newer video formats and better v4l integration (the v4l portions were acked by those maintainers) - typec updates for tiny issues and more typec drivers for new chips. - xhci tiny updates for minor issues - big usb-serial ftdi_sio driver update to handle new devices better - lots of tiny dwc3 fixes and updates for the IP block that is showing up everywhere these days - dts updates for new devices being supported - other tiny janitorial and cleanups fixes for lots of different USB drivers.

usb: chipidea: Add support for VBUS control with PHY

2022-08-31T07:07:52Z

Some platforms make use of VBUS control over PHY which means controller driver has to access PHY registers to turn on/off VBUS line.This patch adds support for such platforms in chipidea.
