From: Ondrej Zary @ 2015-11-17 18:23 UTC (permalink / raw)
To: Martin K. Petersen; +Cc: Christoph Hellwig, linux-scsi
Introduce *_read? and *_write? wrappers to improve code readability.
Also make sure that baseport is always initialized, not only for ATP880.

Move few chip-specifis lines out of is880() and is885() so they become
almost identical.

calls and debug printks), remove is880() and use is885() instead.

From: Ondrej Zary @ 2015-11-17 18:24 UTC (permalink / raw)
To: Martin K. Petersen; +Cc: Christoph Hellwig, linux-scsi
Don't check chip_ver in is870() but add wide_chip parameter for that.
Then add the non-wide support to is885().

Add remaining 870 support to is885():
- different synw, no synuw
- synu[4] = 0x0c
- atp_writeb_io(dev, c, 0x04, 0x00); instead of
atp_writeb_io(dev, c, 0x14, 0x00); (isn't that a bug?)
- atp_writeb_io(dev, c, 0x14, 0xff); instead of
atp_writeb_io(dev, c, 0x14, 0x06);
- different mbuf[3] and mbuf[4] checks

Now that is885() supports everything from is870() and the rest of the code
is almost identical, remove is870() and use is885() instead.

tscam() is using port 0x80 access for delays but that's x86-only.
Use udelay(2) instead.

The ioport region is 0x20 bytes long so accessing 0x3a register using
writeb_io is incorrect. Use writeb_base instead.
There's no change in behavior as 870 chips have ioport = baseport.

Move scsi_host_alloc() to the top of _probe() to remove code duplication,
*p and unneeded atpdev (de)allocation and copying.
While at it, fix the error paths to return real error codes and also add
missing pci_disble_device() call.

Use pci_request_regions and do it before accessing the I/O ports.
Also add missing pci_disable_device() call to atp870u_remove().

Allocate IRQ later during probe to avoid code duplication and also remove
the need for weird locking in _probe.
(It was probably there to prevent race with the IRQ handler?)

Call _init_tables before chip-specific initialization. This avoids code
duplication and fixes a bug(?) in 880 init where the values read from flash
into atpdev->sp are then overwritten by calling init_tables.

Queued for 4.5.
