Subject: [PATCH v2 4/4] parport: add iomem type for parport
From: weiyufeng <weiyufeng@...inos.cn>
Solve the problem of not being able to use LPC and PCIE parallel
ports simultaneously on the phytium platform.Optimize lpc and
pci parallel port program. add iomem type for parport.
In DSDT,LPT recommends the following description:
Device (LPT)
{
Name (_HID, EisaId ("PNP0400") /* Standard LPT Parallel Port */)
Name (_UID, Zero) // _UID: Unique ID
Name (_DDN, "LPT1") // _DDN: DOS Device Name
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
Memory32Fixed (ReadWrite,
0x20000378, // Address Base
0x00000008, // Address Length
)
IRQNoFlags ()
{7}
})
}
