This adds a bunch of patches for the v6.1 Gemini kernel. For v5.15 this was down to a single upstream patch, but for kernel v6.2 I reworked the USB code for FOTG210, so instead of carrying over the half-baked and incomplete patch from v5.15 I just backported all the v6.2 patches, 31 in total, as it creates full device USB mode for e.g. D-Link DNS-313.

Subject: [PATCH 11/29] fotg210-udc: Get IRQ using platform_get_irq()
|
|
|
|
The platform_get_irq() is necessary to use to get dynamic
|
|
IRQ resolution when instantiating the device from the
|
|
device tree. IRQs are not passed as resources in that
|
|
case.
