From: 412574090 @ 2024-10-25 8:21 UTC (permalink / raw)
To: sudipm.mukherjee; +Cc: linux-kernel, xiongxin, weiyufeng
From: weiyufeng <weiyufeng@kylinos.cn>
change struct parport member base and base_hi to iobase and iobase_hi
for ioport. because iomem type will be added, in that case,mapbase,
mapbase_hi will be added in struct parport. this can distinguish between
these two types.

From: 412574090 @ 2024-10-25 8:21 UTC (permalink / raw)
To: sudipm.mukherjee; +Cc: linux-kernel, xiongxin, weiyufeng
From: weiyufeng <weiyufeng@kylinos.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}
})
}
