MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

The linux/irqchip/mips-gic.h header is now almost empty. Move the
declarations of gic_get_c0_compare_int(), gic_get_c0_perfcount_int() &
gic_get_c0_fdc_int() to asm/mips-gic.h in order to close in on being
able to delete the former header.

Move the definition of VP-local interrupts provided by the MIPS Global
Interrupt Controller to the new asm/mips-gic.h header to be alongside
the new accessor functions. Whilst at it, convert to an enum which lends
itself more easily to expansion & documentation.

This patch introduces a new header providing accessor functions for the
MIPS Global Interrupt Controller (GIC) mirroring those provided for the
other 2 components of the MIPS Coherent Processing System (CPS) - the
Coherence Manager (CM) & Cluster Power Controller (CPC).
This header makes use of the new standardised CPS accessor macros where
possible, but does require some custom accessors for cases where we have
either a bit or a register per interrupt.
A major advantage of this over the existing
include/linux/irqchip/mips-gic.h definitions is that code performing
accesses can become much simpler, for example this:
gic_update_bits(GIC_REG(SHARED, GIC_SH_SET_TRIGGER) +
GIC_INTR_OFS(intr), 1ul << GIC_INTR_BIT(intr),
(unsigned long)trig << GIC_INTR_BIT(intr));
...can become simply:
change_gic_trig(intr, trig);
The accessors handle 32 vs 64 bit in the same way as for CM & CPC code,
which means that GIC code will also not need to worry about the access
size in most cases. They are also accessible outside of
drivers/irqchip/irq-mips-gic.c which will allow for simplification in
the use of the non-interrupt portions of the GIC (eg. counters) which
currently require the interrupt controller driver to expose helper
functions for access.
This patch doesn't change any existing code over to use the new
accessors yet, since a wholesale change would be invasive & difficult to
review. Instead follow-on patches will convert code piecemeal to use
this new header. The one change to existing code is to rename gic_base
to mips_gic_base & make it global, in order to fit in with the naming
expected by the standardised CPS accessor macros.
