| * phy: sun4i-usb: fix dereference of pointer phy0 before it is null checkedColin Ian King2020-06-251-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently pointer phy0 is being dereferenced via the assignment of phy on the call to phy_get_drvdata before phy0 is null checked, this can lead to a null pointer dereference. Fix this by performing the null check on phy0 before the call to phy_get_drvdata. Also replace the phy0 == NULL check with the more usual !phy0 idiom.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms where the MUSB and HCI controllers share PHY0, PHY passby is required when using the HCI controller with the PHY, but it must be disabled when the MUSB controller is used instead.

* phy: core: rework phy_set_mode to accept phy mode and submodeGrygorii Strashko2018-12-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the attempt to add support for Ethernet interface mode PHY (MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and duplicate there values from phy_interface_t enum (or introduce more PHY callbacks) [1]. Both approaches are ineffective and would lead to fast bloating of enum phy_mode or struct phy_ops in the process of adding more PHYs for different subsystems which will make them unmaintainable. As discussed in [1] the solution could be to introduce dual level PHYs mode configuration - PHY mode and PHY submode. The PHY mode will define generic PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem specific interface mode. The last is usually already defined in corresponding subsystem headers (phy_interface_t for Ethernet, enum usb_device_speed for USB). This patch is cumulative change which refactors PHY framework code to support dual level PHYs mode configuration - PHY mode and PHY submode. It extends .set_mode() callback to support additional parameter "int submode" and converts all corresponding PHY drivers to support new .set_mode() callback declaration. The new extended PHY API int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode) is introduced to support dual level PHYs mode configuration and existing phy_set_mode() API is converted to macros, so PHY framework consumers do not need to be changed (~21 matches).

* phy: allwinner: sun4i-usb: poll vbus changes on A23/A33 when driving VBUSChen-Yu Tsai2018-03-121-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AXP223 PMIC, like the AXP221, does not generate VBUS change interrupts when N_VBUSEN is used to drive VBUS for the OTG port on the board. This was not noticed until recently, as most A23/A33 boards use a GPIO pin that does not support interrupts for OTG ID detection. This forces the driver to use polling. However the A33-OlinuXino uses a pin that does support interrupts, so the driver uses them. However the VBUS interrupt never fires, and the driver never gets to update the VBUS status. This results in musb timing out waiting for VBUS to rise. This was worked around for the AXP221 by resorting to polling changes in commit 91d96f06a760 ("phy-sun4i-usb: Add workaround for missing Vbus det interrupts on A31"). This patch adds the A23 and A33 to the list of SoCs that need the workaround.

| | | | | | | | | | | | | | | | On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires two clocks instead of one. On all Allwinner SoCs that share the common USB PHY design supported by the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there is at most one HSIC PHY, typically the last. In this patch we take advantage of these known constraints and store an index in the compatible-string-related config structure describing which PHY is HSIC, needing the extra hsic_12M clock.

* phy: allwinner: phy-sun4i-usb: Add log when probingQuentin Schulz2017-07-211-5/+20
| | | | | | | | | | | | When phy-sun4i-usb's probing fails, it does not print the reason in kernel log, forcing the developer to edit this driver to add info logs. This commit makes the kernel print the reason of phy-sun4i-usb's probing failure or a success message.

* phy: Group vendor specific phy driversVivek Gautam2017-06-014-0/+1126
Adding vendor specific directories in phy to group phy drivers under their respective vendor umbrella. Also updated the MAINTAINERS file to reflect the correct directory structure for phy drivers.
