phy: samsung: Do not enable PHY_EXYNOS5_USBDRD by default during compile testing

2025-04-11T07:18:34+00:00

Enabling the compile test should not cause automatic enabling of all drivers. Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250404121326.318936-2-krzysztof.kozlowski@linaro.org Signed-off-by: Vinod Koul

phy: exynos5-usbdrd: Do not depend on Type-C

2025-02-27T12:25:46+00:00

Older Exynos designs, like Exynos5422, do not have USB Type-C and the USB DRD PHY does not really need CONFIG_TYPEC for these devices at all. Incorrectly added optional dependency on CONFIG_TYPEC caused this driver to be missing for exynos_defconfig and as result Exynos5422-based boards like Hardkernel Odroid HC1 failed to probe USB.

phy: exynos5-usbdrd: subscribe to orientation notifier if required

2025-02-13T17:12:53+00:00

gs101's SS phy needs to be configured differently based on the connector orientation, as the SS link can only be established if the mux is configured correctly. The code to handle programming of the mux is in place already, this commit now adds the missing pieces to subscribe to the Type-C orientation switch event. Note that for this all to work we rely on the USB controller re-initialising us. It should invoke our .exit() upon cable unplug, and during cable plug we'll receive the orientation event after which we expect our .init() to be called. Above reinitialisation happens if the DWC3 controller can enter runtime suspend automatically. For the DWC3 driver, this is an opt-in: echo auto > /sys/devices/.../11110000.usb/power/control Once done, things work as long as the UDC is not bound as otherwise it stays busy because it doesn't cancel / stop outstanding TRBs. For now we have to manually unbind the UDC in that case: echo "" > sys/kernel/config/usb_gadget/.../UDC Note that if the orientation-switch property is missing from the DT, the code will behave as before this commit (meaning for gs101 it will work in SS mode in one orientation only). Other platforms are not affected either way.

phy: samsung-ufs: switch back to syscon_regmap_lookup_by_phandle()

2024-12-08T16:05:45+00:00

Now exynos-pmu can register its custom regmap for gs101 via of_syscon_register_regmap() we can switch back to the standard syscon_regmap_lookup_by_phandle() api for obtaining the regmap. Additionally add a Kconfig dependency for MFD_SYSCON.

Support for the Exynos4212 SoC was originally dropped as there were no boards using it. We will be adding a device that uses it, so add it back.

phy: exynos: Rename Exynos to lowercase

2020-06-24T17:14:19+00:00

Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website.

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 ...
