49166afb - phy: exynos5-usbdrd: Do not depend on Type-C

Thu, 27 Feb 2025 07:05:18 +0000

phy: exynos5-usbdrd: Do not depend on Type-COlder Exynos designs, like Exynos5422, do not have USB Type-C and theUSB DRD PHY does not really need CONFIG_TYPEC for these devices at all.Incorrectly added optional dependency on CONFIG_TYPEC caused this driverto be missing for exynos_defconfig and as result Exynos5422-based boardslike Hardkernel Odroid HC1 failed to probe USB.Reported-by: Krzysztof Kozlowski Closes: https://krzk.eu/#/builders/21/builds/6139Reported-by: Marek Szyprowski Closes: https://lore.kernel.org/all/3c0b77e6-357d-453e-8b63-4757c3231bde@samsung.com/Fixes: 09dc674295a3 ("phy: exynos5-usbdrd: subscribe to orientation notifier if required")Reviewed-by: André Draszik Tested-by: Marek Szyprowski Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20250227070518.5468-1-krzysztof.kozlowski@linaro.orgSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/phy/samsung/Kconfig

09dc6742 - phy: exynos5-usbdrd: subscribe to orientation notifier if required

Fri, 06 Dec 2024 16:31:06 +0000

phy: exynos5-usbdrd: subscribe to orientation notifier if requiredgs101's SS phy needs to be configured differently based on theconnector orientation, as the SS link can only be established if themux is configured correctly.The code to handle programming of the mux is in place already, this commitnow adds the missing pieces to subscribe to the Type-C orientationswitch event.Note that for this all to work we rely on the USB controllerre-initialising us. It should invoke our .exit() upon cable unplug, andduring cable plug we'll receive the orientation event after which weexpect our .init() to be called.Above reinitialisation happens if the DWC3 controller can enter runtimesuspend automatically. For the DWC3 driver, this is an opt-in: echo auto > /sys/devices/.../11110000.usb/power/controlOnce done, things work as long as the UDC is not bound as otherwise itstays busy because it doesn't cancel / stop outstanding TRBs. For nowwe have to manually unbind the UDC in that case: echo "" > sys/kernel/config/usb_gadget/.../UDCNote that if the orientation-switch property is missing from the DT,the code will behave as before this commit (meaning for gs101 it willwork in SS mode in one orientation only). Other platforms are notaffected either way.Signed-off-by: André Draszik Tested-by: Will McVicker Reviewed-by: Peter Griffin Tested-by: Peter Griffin Link: https://lore.kernel.org/r/20241206-gs101-phy-lanes-orientation-phy-v4-6-f5961268b149@linaro.orgSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/phy/samsung/Kconfig
