I think relase 1.5.0 should be tight to TinyUSB upgrade to v0.17.0~0.
The cache sync and DMA will not work with older versions anyways

There are two ways:
- We can publish this changes and they will work with current version based on v0.15, but only in a Single IRQ mode.
- After tinyusb will be published, it will start to use DMA

esp_tinyusb component, v1.5.0
Description
DMA support for TinyUSB device stack.
DMA (Buffer mode) is a default mode for device, meanwhile there is an option to change the mode to Single/IRQ by disabling DMA mode via menuconfig.
If (by any reason) hardware isn't support DMA (
arch != GHWCFG2_ARCH_INTERNAL_DMA) then the Single/IRQ mode will be used.Related
