VT6420 seems to have the same hotplug capability as VT6421.
However, enabling hotplug needs to expose SCR registers which can cause
problems. It works for me but might break elsewhere. So add a module
parameter vt6420_hotplug to enable this feature.

While most hardware will simply ignore a write to a read-only register,

This adds a driver for the Faraday Technology FTIDE010
PATA IP block.
When used with the Storlink/Storm/Cortina Systems Gemini
SoC, the PATA interface is accompanied by a PATA<->SATA
bridge, so while the device appear as a PATA controller,
it attaches physically to SATA disks, and also has a
designated memory area with registers to set up the bridge.
The Gemini SATA bridge is separated into its own driver
file to make things modular and make it possible to reuse
the PATA driver as stand-alone on other systems than the
Gemini.

devm_ioremap_resource() enforces that there are no overlapping
resources, where as devm_ioremap() does not. The sata phy driver needs
a subset of the sata IO address space, so maps some of the sata
address space. As a result, sata_mv now fails to probe, reporting it
cannot get its resources, and so we don't have any SATA disks.

When platform_get_irq() fails, it returns an error code, which
libahci_platform and replaces it by -EINVAL. This commit fixes that by
propagating the error code. It fixes the situation where
platform_get_irq() returns -EPROBE_DEFER because the interrupt
controller is not available yet, and generally looks like the right
thing to do.
We pay attention to not show the "no irq" message when we are in an
EPROBE_DEFER situation, because the driver probing will be retried
later on, once the interrupt controller becomes available to provide
the interrupt.

(Correction in this resend: fixed function name acer_sa5_271_workaround; fixed
the always-true condition in the function; fixed description.)
On the Acer Switch Alpha 12 (model number: SA5-271), the internal SSD may not
get detected because the port_map and CAP.nr_ports combination causes the driver
to skip the port that is actually connected to the SSD. More specifically,
either all SATA ports are identified as DUMMY, or all ports get ``link down''
and never get up again.
This problem occurs occasionally. When this problem occurs, CAP may hold a
value of 0xC734FF00 or 0xC734FF01 and port_map may hold a value of 0x00 or 0x01.
When this problem does not occur, CAP holds a value of 0xC734FF02 and port_map
may hold a value of 0x07. Overriding the CAP value to 0xC734FF02 and port_map to
0x7 significantly reduces the occurrence of this problem.
