[PATCH v3 0/2] serial: 8250: Apply FSL workarounds also without SERIAL_8250_CONSOLE

[Uwe Kleine-König]

Hello,

this is v3 of the series that now also copes for
arch/powerpc/kernel/legacy_serial.c using fsl8250_handle_irq().

For kernel configurations that already before were correctly using the
Freescale workarounds, this is the case with this series applied, too.
So in all cases the situation doesn't get worse. The upside is that even
with the 8250 driver compiled as a module (or built-in but without
console support) the workarounds are now applied for all devices but for
the ones instantiated in arch/powerpc/kernel/legacy_serial.c. (And even
for these there might not be a problem as they might benefit from
enabling the workarounds in drivers/tty/serial/8250/8250_of.c. Not sure
though.)

Patch #1 is new here. Patch #2 only changed lightly: I restored
alphabetic order in drivers/tty/serial/8250/Kconfig.

As patch #1 is needed for patch #2 to not introduce a build failure,
both patches should be taken together. I suggest to add them to Greg's
serial tree, but the changes pending there should not conflict with this
series such that taking them both via powerpc works, too.

Best regards
Uwe
