usb: ehci-mx6: Add i.MX95 OTG support

2025-08-23T16:17:59+00:00

When the usb node is defined dr_mode="otg" ehci_usb_phy_mode() is called
to determine the mode from status registers.

The IMX95RM does not currently define the USBNC STATUS register but it is
assumed to be an omission as the first three registers are defined.
It has been expirimentally verified that the USBNC_PHY_STATUS register
at offset 0x23C bit4 (USBNC_PHYSTATUS_ID_DIG) reads 0 when USB_ID is GND
and 1 when floating.

Use is_imx9() as this driver works for i.MX91, i.MX93 and i.MX95 and all
of these determine the role based on the USBNC_PHY_STATUS register.

usb: dwc2: Replace uint_t types with u

2025-06-02T07:57:43+00:00

Updates all instances of uint8_t, uint16_t, and uint32_t to u8, u16, and
u32 respectively, ensuring consistent use of kernel-preferred types and
resolving checkpatch.pl warnings.

usb: dwc2: Unify flush and reset logic with v4.20a support

2025-06-02T07:57:43+00:00

This patch merges flush and reset logic for both host and gadget code
into a common set of functions, reducing duplication. It also adds support
for the updated reset logic to compatible with core version since v4.20a.

This patch mainly refers to the patch in the kernel.

Some macros are shared between host and gadget code, causing duplicated
definitions. Move DWC2 macro definitions from host and gadget code into a
common header to reduce duplication.

usb: dwc2: Fix HBstLen setting for external DMA mode

The loop used to calculate HBstLen for extern DMA mode does not produce
the correct result according to the datasheet [1]. Replacing that loop
with a direct calculation using LOG2 to correctly assign the burst length
in the GAHBCFG register for external DMA mode.

usb: dwc2: Fix incorrect ULPI_UTMI_SEL bit setting

2025-06-02T07:57:25+00:00

The ULPI_UTMI_SEL bit in the DWC2 driver was set incorrectly. According
to the datasheet [1], this bit should be set to 0 for UTMI interface and 1
for ULPI interface. The existing code had this logic reversed,
causing the interface selection to be incorrect.

This commit corrects the ULPI_UTMI_SEL bit setting to match the
datasheet's description. Referencing the kernel's code [2] also confirms
this fix.
