This update is required to be serialized to the instruction stream meaning that after this update completes, it takes effect immediately and no exceptions of lower priority than the new boosted priority can pre-empt execution. Because of this erratum, the priority boosting does not take place immediately, allowing the instruction after the MSR to be interrupted by an exception of lower priority than the new boosted priority. This effect is only limited to the next instruction. Subsequent instructions are guaranteed to see the new boosted priority.
This was raised in Bitbucket issue 113 from Vadzim Dambrouski.
No... I was misled. The shutdown function is usually called when the
driver is unlinked. But not in this case. In this case, it is simply
called when the last reference is closed. And no, you don't want to
detach the interrupt handler in that case. My bad.
This reverts commit b79e6b9c9a.
stm32f746g-disco: touchscreen support
* fixed FT5x06 driver to correctly close (previously it unregistered interrupt handler during close)
* added LittlevGL demo for STM32F746G-DISCO

Squashed commit of the following:
arch/arm/src/samd5e5/sam_usb.c: USB driver now compiles with some issues.
arch/arm/src/samd5e5/chip/sam_fuses.h: Add fuse definition header file.
arch/arm/src/samd5e5: Bring USB driver in from SAMD2L2.
sched/mqueue/mq_notify.c: Fix - only part of struct copied to internal structure
As source adress the adress of the struct member sigev_value was used,
and it is not located the start of the struct.
This leads to invalid data being copied to internal structure.
Both source and destination should be of type struct sigevent* .
