Merge tag 'usb-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/Thunderbolt/PHY driver updates from Greg KH: "Here is the big USB and Thunderbolt and PHY driver updates for 5.6-rc1. With the advent of USB4, "Thunderbolt" has really become USB4, so the renaming of the Kconfig option and starting to share subsystem code has begun, hence both subsystems coming in through the same tree here. PHY driver updates also touched USB drivers, so that is coming in through here as well. Major stuff included in here are: - USB 4 initial support added (i.e. Thunderbolt) - musb driver updates - USB gadget driver updates - PHY driver updates - USB PHY driver updates - lots of USB serial stuff fixed up - USB typec updates - USB-IP fixes - lots of other smaller USB driver updates All of these have been in linux-next for a while now (the usb-serial tree is already tested in linux-next on its own before merged into here), with no reported issues" [ Removed an incorrect compile test enablement for PHY_EXYNOS5250_SATA that causes configuration warnings - Linus ] * tag 'usb-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (207 commits) Doc: ABI: add usb charger uevent usb: phy: show USB charger type for user usb: cdns3: fix spelling mistake and rework grammar in text usb: phy: phy-gpio-vbus-usb: Convert to GPIO descriptors USB: serial: cyberjack: fix spelling mistake "To" -> "Too" USB: serial: ir-usb: simplify endpoint check USB: serial: ir-usb: make set_termios synchronous USB: serial: ir-usb: fix IrLAP framing USB: serial: ir-usb: fix link-speed handling USB: serial: ir-usb: add missing endpoint sanity check usb: typec: fusb302: fix "op-sink-microwatt" default that was in mW usb: typec: wcove: fix "op-sink-microwatt" default that was in mW usb: dwc3: pci: add ID for the Intel Comet Lake -V variant usb: typec: tcpci: mask event interrupts when remove driver usb: host: xhci-tegra: set MODULE_FIRMWARE for tegra186 usb: chipidea: add inline for ci_hdrc_host_driver_init if host is not defined usb: chipidea: handle single role for usb role class usb: musb: fix spelling mistake: "periperal" -> "peripheral" phy: ti: j721e-wiz: Fix build error without CONFIG_OF_ADDRESS USB: usbfs: Always unlink URBs in reverse order ...

phy: samsung: disable bind/unbind platform driver feature

2019-08-23T04:10:59+00:00

Samsung PHY drivers control the power to the SoC core components needed by their client devices (USB HCDs, SATA, camera ISP bridge, DP encoder) to properly operate. Disabling PHYs in runtime usually causes the client device to crash with external abort exception or similar issue due to lack of API to notify clients about PHY removal. This patch removes the possiblity to unbind Samsung Exynos PHY drivers in runtime. Signed-off-by: Marek Szyprowski Signed-off-by: Kishon Vijay Abraham I

phy: samsung: Use struct_size() in devm_kzalloc()

2019-06-20T08:43:57+00:00

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct samsung_usb2_phy_driver { ... struct samsung_usb2_phy_instance instances[0]; }; instance = devm_kzalloc(dev, sizeof(struct samsung_usb2_phy_driver) + count * sizeof(struct samsung_usb2_phy_instance), GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, instances, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

phy: exynos5-usbdrd: Calibrate LOS levels for exynos5420/5800

2017-12-29T07:30:35+00:00

Adding phy calibration sequence for USB 3.0 DRD PHY present on Exynos5420/5800 systems. This calibration facilitates setting certain PHY parameters viz. the Loss-of-Signal (LOS) Detector Threshold Level, as well as Tx-Vboost-Level for Super-Speed operations. Additionally we also set proper time to wait for RxDetect measurement, for desired PHY reference clock, so as to solve issue with enumeration of few USB 3.0 devices, like Samsung SUM-TSB16S 3.0 USB drive on the controller. We are using CR_port for this purpose to send required data to override the LOS values. On testing with USB 3.0 devices on USB 3.0 port present on SMDK5420, and peach-pit boards should see following message: usb 2-1: new SuperSpeed USB device number 2 using xhci-hcd and without this patch, should see below shown message: usb 1-1: new high-speed USB device number 2 using xhci-hcd [Also removed unnecessary extra lines in the register macro definitions] Signed-off-by: Vivek Gautam [adapted to use phy_calibrate as entry point] Signed-off-by: Andrzej Pietrasiewicz Acked-by: Felipe Balbi Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Kishon Vijay Abraham I
