usb: musb: sunxi: Introduce config struct

2023-02-02T10:13:42+00:00

Currently the probe routine explicitly compares the compatible string of the device node to figure out which features and quirks a certain Allwinner MUSB model requires. This gets harder to maintain for new SoCs. Add a struct sunxi_musb_cfg that names the features and quirks explicitly, and create instances of this struct for every type of MUSB device we support. Then bind this to the compatible strings via the OF data feature.

usb: musb: sunxi: add support for the F1C100s MUSB controller

2023-02-02T10:13:42+00:00

The suniv SoC has a MUSB controller like the one in A33, but with a SRAM region to be claimed. Add support for it.

usb: musb: mediatek: don't unregister something that wasn't registered

2023-02-02T10:12:02+00:00

This function only calls mtk_otg_switch_init() when the ->port_mode is MUSB_OTG so the clean up code should only call mtk_otg_switch_exit() for that mode.

usb: musb: fix error return code in omap2430_probe()

2023-01-17T16:05:58+00:00

Before calling platform_get_resource() in omap2430_probe(), the 'ret' is re-assgined to 0, it can't return an error code, if platform_get_resource fails. Set the error code to -EINVAL to fix this.

usb: musb: remove extra check in musb_gadget_vbus_draw

2022-12-08T15:44:39+00:00

The checks for musb->xceiv and musb->xceiv->set_power duplicate those in usb_phy_set_power(), so there is no need of them. Moreover, not calling usb_phy_set_power() results in usb_phy_set_charger_current() not being called, so current USB config max current is not propagated through USB charger framework and charger drivers may try to draw more current than allowed or possible. Fix that by removing those extra checks and calling usb_phy_set_power() directly.

usb: musb: Drop old unused am35x glue layer

2022-11-29T07:56:09+00:00

The am35x glue layer is no longer in use and can be dropped. There are no longer any SoCs passing platform data for it as they are booting using devicetree. In general, the am35x SoCs are similar to am335x and ti81xx and can use the musb_dsps glue layer as long as there is a proper phy driver available.

usb: musb: omap2430: Fix probe regression for missing resources

2022-11-22T16:30:12+00:00

Probe for omap2430 glue layer is now broken for interrupt resources in all cases. Commit 239071064732 ("partially Revert "usb: musb: Set the DT node on the child device"") broke probing for SoCs using ti-sysc interconnect target module as the dt node is not found. Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as the IRQ resources are no longer automatically populated from devicetree. Let's fix the issues by calling device_set_of_node_from_dev() only if the SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's populate the resources manually as needed. Note that once we have updated the SoCs to probe with proper devicetree data in all cases, this is no longer needed. But doing that requires patching both devicetree and SoC code, so let's fix the probe issues first.
