* phy: Switch back to struct platform_driver::remove()Uwe Kleine-König2024-10-171-4/+4
| | | | | | | | | | | | | | | | | | After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/phy/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

* phy: Explicitly include correct DT includesRob Herring2023-07-172-2/+1
| | | | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

| | | | | | | | | | | | | | It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties.

* phy: allwinner: phy-sun4i-usb: Convert to platform remove callback returning ↵Uwe Kleine-König2023-03-201-4/+2
| | | | | | | | | | | | | | | | | | | | void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* phy: sun4i-usb: Replace types with explicit quirk flagsAndre Przywara2023-01-121-36/+15
| | | | | | | | | | | | | | | | So far we were assigning some crude "type" (SoC name, really) to each Allwinner USB PHY model, then guarding certain quirks based on this. This does not only look weird, but gets more or more cumbersome to maintain. Remove the bogus type names altogether, instead introduce flags for each quirk, and explicitly check for them. This improves readability, and simplifies future extensions.

* phy: sun4i-usb: Introduce port2 SIDDQ quirkAndre Przywara2022-11-071-0/+59
| | | | | | | | | | | | | | | | | | | At least the Allwinner H616 SoC requires a weird quirk to make most USB PHYs work: Only port2 works out of the box, but all other ports need some help from this port2 to work correctly: The CLK_BUS_PHY2 and RST_USB_PHY2 clock and reset need to be enabled, and the SIDDQ bit in the PMU PHY control register needs to be cleared. For this register to be accessible, CLK_BUS_ECHI2 needs to be ungated. Don't ask .... Instead of disguising this as some generic feature, treat it more like a quirk (what it really is): If the quirk bit is set, and we initialise a PHY other than PHY2, ungate this one special clock, and clear the SIDDQ bit. We also pick the clock and reset from PHY2 and enable them as well.

* 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.
