在linux内核的musb_core.c中irqreturn_t musb_interrupt(struct musb *musb)函数内有一段话:
/**
* According to Mentor Graphics' documentation, flowchart on page 98,
* IRQ should be handled as follows:
*
* . Resume IRQ
* . Session Request IRQ
* . VBUS Error IRQ
* . Suspend IRQ
* . Connect IRQ
* . Disconnect IRQ
* . Reset/Babble IRQ
* . SOF IRQ (we're not using this one)
* . Endpoint 0 IRQ
* . TX Endpoints
* . RX Endpoints
*
* We will be following that flowchart in order to avoid any problems
* that might arise with internal Finite State Machine.
*/
请问,这里的“Mentor Graphics' documentation”在哪里能下载,是否公开的寄存器描述文档?
