usb: phy: twl6030-usb: Fix a resource leak in an error handling path in 'twl6030_usb_probe()'

2020-05-09T08:05:08Z

A call to 'regulator_get()' is hidden in 'twl6030_usb_ldo_init()'. A corresponding put must be performed in the error handling path, as already done in the remove function. While at it, also move a 'free_irq()' call in the error handling path in order to be consistent. Reviewed-by: Dan Carpenter Signed-off-by: Christophe JAILLET Signed-off-by: Felipe Balbi

usb: phy: Add driver for the Ingenic JZ4770 USB transceiver

usb: phy: tegra: Include proper GPIO consumer header to fix compile testing

2020-03-04T09:51:21Z

The driver uses only GPIO Descriptor Consumer Interface so include proper header. This fixes compile test failures (e.g. on i386): drivers/usb/phy/phy-tegra-usb.c: In function ‘ulpi_phy_power_on’: drivers/usb/phy/phy-tegra-usb.c:695:2: error: implicit declaration of function ‘gpiod_set_value_cansleep’ [-Werror=implicit-function-declaration] drivers/usb/phy/phy-tegra-usb.c: In function ‘tegra_usb_phy_probe’: drivers/usb/phy/phy-tegra-usb.c:1167:11: error: implicit declaration of function ‘devm_gpiod_get_from_of_node’ [-Werror=implicit-function-declaration] Signed-off-by: Krzysztof Kozlowski Reviewed-by: Dmitry Osipenko Link: https://lore.kernel.org/r/1583234960-24909-1-git-send-email-krzk@kernel.org Signed-off-by: Greg Kroah-Hartman

usb: phy: tegra: Add clarifying comments about the shared registers

2020-02-10T19:12:15Z

Tools like Coccinelle may erroneously recommend to use the devm_platform_ioremap_resource() API for the registers mapping because these tools are not aware about the implementation details of the driver. Let's add a clarifying comments to the code, which should help to stop future attempts to break the driver.

usb: phy: phy-gpio-vbus-usb: Convert to GPIO descriptors

2020-01-23T18:20:57Z

Instead of using the legacy GPIO API and keeping track on polarity inversion semantics in the driver, switch to use GPIO descriptors for this driver and change all consumers in the process. This makes it possible to retire platform data completely: the only remaining platform data member was "wakeup" which was intended to make the vbus interrupt wakeup capable, but was not set by any users and thus remained unused. VBUS was not waking any devices up. Leave a comment about it so later developers using the platform can consider setting it to always enabled so plugging in USB wakes up the platform.

usb: phy-generic: Delete unused platform data

2020-01-15T09:39:20Z

The last user of the phy generic platform data was deleted in commit 1e041b6f313aaa966612a7e415cfc09c90d6b829 ("usb: dwc3: exynos: Remove dead code"). So get rid of the platform data, which rids us of another consumer of the legacy GPIO API at the same time. Make sure we only inlcude which is all we use. Alter the usb_phy_gen_create_phy() function prototype to not pass any platform data as this is just hardcoded to NULL at all locations calling it in the kernel. Move the devm_gpiod_get* calls out of the if (of_node) parenthesis, as these calls are generic and do not depend on device tree, they are used by any hardware description.

usb: phy: tegra: Move utmip_pad_count checking under lock

2020-01-09T15:21:58Z

It's unlikely that two drivers could manage PHY's state simultaneously in practice, nevertheless the utmip_pad_count checking should be under lock, for consistency.
