usb: dwc2: Fix the write to W1C fields in HPRT register

2023-06-21T11:15:58Z

Fix the write to the HPRT register which treat W1C fields as if they were mere RW. This leads to unintended clearing of such fields This bug was found during the testing on Simics model. Referring to specification DesignWare Cores USB 2.0 Hi-Speed On-The-Go (OTG) Databook (3.30a)"5.3.4.8 Host Port Control and Status Register (HPRT)", the HPRT.PrtPwr is cleared by this mistake. In the Linux driver (contrary to U-Boot), HPRT is always read using dwc2_read_hprt0 helper function which clears W1C bits. So after write back those bits are zeroes. Signed-off-by: Teik Heng Chong

bootstd: usb: Avoid initing USB twice

2023-05-13T13:52:32Z

This causes crashes on some boards, e.g. rockpro64. In any case, we should not do it. Check the usb_started flag to avoid this. Signed-off-by: Simon Glass Tested-by: Jonas Karlman Tested-by: Tom Rini

usb: Tidy up the usb_start flag

2023-05-13T13:52:32Z

This should be declared in a header file so that type-checking works correctly. Add a single declaration to usb.h and remove the others. Signed-off-by: Simon Glass Reviewed-by: Marek Vasut Reviewed-by: Patrick Delaunay

drivers: use dev_read_addr_ptr when cast to pointer

2023-05-06T09:28:18Z

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU can expect 64-bit data from the device tree parser, so use dev_read_addr_ptr instead of the dev_read_addr function in the various files in the drivers directory that cast to a pointer. As we are there also streamline the error response to -EINVAL on return. Signed-off-by: Johan Jonker Reviewed-by: Simon Glass

usb: ehci-mx6: move phy setup before register access

2023-05-02T08:57:32Z

For the CONFIG_PHY case, move the PHY setup before the register access. This avoids a hang when updating the imx8mm.dtsi which moves the USB OTG power-domains to the PHY. Signed-off-by: Tim Harvey Tested-by: Fabio Estevam

usb: xhci-mtk: modify the SOF/ITP interval for mt8195

2023-03-02T21:43:43Z

There are 4 USB controllers on MT8195, the controllers (IP1~IP3, exclude IP0) have a wrong default SOF/ITP interval which is calculated from the frame counter clock 24Mhz by default, but in fact, the frame counter clock is 48Mhz, so we shall set the accurate interval according to 48Mhz for those controllers. Note: The first controller no need set it, but if set it, shall change tphy's pll at the same time. Signed-off-by: Chunfeng Yun Reviewed-by: Marek Vasut

Correct SPL uses of IMX_MODULE_FUSE

2023-02-10T12:41:39Z

This converts 6 usages of this option to the non-SPL form, since there is no SPL_IMX_MODULE_FUSE defined in Kconfig Signed-off-by: Simon Glass
