mips: mt: make mt_class constant

2024-03-07T16:18:50+00:00

Since commit 43a7206b0963 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the mt_class structure to be declared at build time placing
it into read-only memory, instead of having to be dynamically allocated at
boot time.

MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35+00:00

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.

Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.

Hence replace setup_irq() by request_irq().

remove_irq() has been replaced by free_irq() as well.

There were build error's during previous version, couple of which was
reported by kbuild test robot  of which one was reported
by Thomas Bogendoerfer  as well. There were a
few more issues including build errors, those also have been fixed.

MIPS: APRP: Fix an issue when device_create() fails.

2014-08-01T15:30:35+00:00

If a call to device_create() fails for a channel during the initialize
loop, we need to clean the devices entries already created before
leaving.

MIPS: MT: Remove SMTC support

2014-05-23T22:07:01+00:00

Nobody is maintaining SMTC anymore and there also seems to be no userbase.
Which is a pity - the SMTC technology primarily developed by Kevin D.
Kissell  is an ingenious demonstration for the MT
ASE's power and elegance.

Based on Markos Chandras  patch
https://patchwork.linux-mips.org/patch/6719/ which while very similar did
no longer apply cleanly when I tried to merge it plus some additional
post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to
merge once upon a time.

MIPS: APRP: Unregister rtlx interrupt hook at module exit

2014-03-06T19:55:07+00:00

If the aprp_hook is not assigned back to NULL, it will still be called
after module exits. This is not wanted.

MIPS: APRP: Split RTLX support into separate files.

2014-01-22T19:19:02+00:00

Split the RTLX functionality in preparation for adding support for CMP
platforms. Common functions remain in the original file and a new file
contains code specific to platforms that do not have a CMP.
