This commit adds/updates the USB PHY related HAL APIs. The following changes
are made:
- Updated 'usb_wrap_hal.h' API
- Added 'usb_serial_jtag_hal.h' API
This commit updates updates the LLs of USB WRAP and USJ as follows:
- Added missing 'usb_wrap_ll.h' and 'usb_serial_jtag_ll.h' for the ESP32-P4
- Added LL cap macros to distinguish feature differences between the LLs of
different targets:
- '..._LL_EXT_PHY_SUPPORTED' indicates whether the USB WRAP/USJ supports
routing to an external FSLS PHY.
- '..._LL_SWAP_PHY_SUPPORTED' indicates whether the USB WRAP/USJ supports
swapping between multiple internal FSLS PHYs.
- Tidied up some RCC LL functions and their callers.
- Added 'usb_wrap_types.h' and 'usb_serial_jtag_types.h' to provide types used
in LLs.
- Fixed some spelling/naming issues as part of code-spell pre-commit
This commit rewrite the 'usb_wrap_ll.h' API as follows:
- All APIs renamed from 'usb_fsls_phy_ll_...()' to 'usb_wrap_ll_...()'
- APIs now match their equivalent counter parts in 'usb_serial_jtag_ll.h'
For targets that only contain a USJ peripheral (and not a DWC OTG), their
'usb_fsls_phy_ll.h' headers only contain a single function
('usb_fsls_phy_ll_int_jtag_enable()') whose feature is already covered by
functions in 'usb_serial_jtag_ll.h'. Thus, this header is redundant.
This commit does the following:
- Remove 'usb_fsls_phy_ll.h' for targets that only contain a USJ peripheral
- Rename 'usb_fsls_phy_[hal|ll].[h|c]' to `usb_wrap_[hal|ll].[h|c]` for targets
that contain a DWC OTG peripheral. This better reflects the underlying peripheral
that the LL header accesses.
- Renamed usb_otg_periph.h/c to usb_dwc_periph.h/c to match naming convention
of other DWC OTG related files
- Added compatibility header for usb_otg_periph.h
This commit renames USB PHY related HAL files from "usb_phy_xxx" to
"usb_fsls_phy_xxx" since they are only designed to support Full-Speed/Low-Speed
Serial USB PHYs. This renmaing is done to accommodate future USB PHYs that use
other PHY interfaces (e.g., UTMI, ULPI etc).
peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
