irqchip: mips-gic: Remove linux/irqchip/mips-gic.h

2017-09-04T11:53:14+00:00

The linux/irqchip/mips-gic.h header is no longer used. Remove it. Signed-off-by: Paul Burton Acked-by: Marc Zyngier Cc: Jason Cooper Cc: Thomas Gleixner Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/17049/ Signed-off-by: Ralf Baechle

MIPS: VDSO: Avoid use of linux/irqchip/mips-gic.h

2017-09-04T11:53:14+00:00

Our VDSO code makes use of macros from linux/irqchip/mips-gic.h to provide offsets to register values, but these are trivial offsets to the two 32 bit halves of a 64 bit value. Replace use of the macros with zero (ie. omit adding an offset) and the size of the low 32 bit of the value. This removes our need for linux/irqchip/mips-gic.h & prepares us for it to be removed.

irqchip: mips-gic: Move gic_get_c0_*_int() to asm/mips-gic.h

2017-09-04T11:53:14+00:00

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.

irqchip: mips-gic: Remove gic_present

2017-09-04T11:53:14+00:00

Nothing uses the global gic_present variable anymore; mips_gic_present() should be used instead. Remove the dead code.

irqchip: mips-gic: Remove gic_init()

2017-09-04T11:53:14+00:00

All in-tree platforms now probe the GIC driver using device tree, and as such nothing calls gic_init() any longer. Remove the dead code.

irqchip: mips-gic: Remove gic_get_usm_range()

2017-09-04T11:53:14+00:00

The MIPS VDSO code is no longer reliant upon the irqchip driver to provide the address of the GIC's user-visible section via gic_get_usm_range(). Remove the now-dead code.

irqchip: mips-gic: Move various definitions to the driver

2017-09-04T11:53:14+00:00

Move the definitions of macros used to convert between hardware IRQ numbers & shared or local interrupt numbers into the irqchip driver, which is all that should ever need to care about them. Remove GIC_CPU_TO_VEC_OFFSET() in the process since it's never used.

irqchip: mips-gic: Remove GIC_CPU_INT* macros

2017-09-04T11:53:14+00:00

The GIC_CPU_INT* macros are never used. Remove the dead code. Signed-off-by: Paul Burton Acked-by: Marc Zyngier Cc: Jason Cooper Cc: Thomas Gleixner Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/17038/ Signed-off-by: Ralf Baechle

MIPS: GIC: Move GIC_LOCAL_INT_* to asm/mips-gic.h

2017-09-04T11:53:14+00:00

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.

irqchip: mips-gic: Convert remaining local reg access to new accessors

2017-09-04T11:53:14+00:00

Convert the remaining accesses to registers in the GIC VP-local & VP-other register blocks to use the new accessor functions provided by asm/mips-gic.h, resulting in code which is often shorter & easier to read.
