Currently on powerpc we have our own #define for the highest (negative)

Implement irq_chip->irq_get_irqchip_state to make it possible for PMIC
block drivers to access the IRQ real time status bits. The status bits
are used for various kinds of input signals, e.g. GPIO.

Add callback that is called by epautoconf to allow UDC driver match the
best endpoint for specific descriptor. It's intended to supply mechanism

Move find_ep() function to gadget.h, rename it to gadget_find_ep_by_name()
and make it static inline. It can be used in UDC drivers, especially in
'match_ep' callback after moving chip-specific endpoint matching logic from
epautoconf to UDC drivers.

As function ep_matches() is used to match endpoint with usb descriptor it's
highly unintuitive that it modifies endpoint and descriptor structures fields.
This patch moves code configuring ep and desc from ep_matches() to
usb_ep_autoconfig_ss(), so now function ep_matches() does nothing more than
Move ep_matches() function to udc-core and rename it to
usb_gadget_ep_match_desc(). This function can be used by UDC drivers

flags. We check if endpoint supports transfer type and direction requested
in ep descriptor. Since we have this new endpoint matching mechanism
there is no need to have old code guessing endpoint capabilities basing
