• bb6652363   drivers/irqchip: xtensa: add warning to irq_retrigger ... Browse Code »

  XEA2 and MX PIC can only retrigger software interrupts. Issue a warning
  if an interrupt of any other type is retriggered.

• cad6fade6   xtensa: clean up WSR*/RSR*/get_sr/set_sr ... Browse Code »

  WSR and RSR are too generic and collide with other macro definitions in
  the kernel causing warnings in allmodconfig builds. Drop WSR and RSR
  macros and WSR_* and RSR_* variants. Change get_sr and set_sr to
  xtensa_get_sr and xtensa_set_sr. Fix up users.

• 8b5163eb9   xtensa: drop variant IRQ support ... Browse Code »

  If an xtensa core provides an additional IRQ controller it should be
  treated as a separate piece of hardware and be driven by an irqchip
  driver.

• e5c86679d   xtensa: don't use linux IRQ #0 ... Browse Code »

  Linux IRQ #0 is reserved for error reporting and may not be used.
  Increase NR_IRQS for one additional slot and increase
  irq_domain_add_legacy parameter first_irq value to 1, so that linux
  IRQ #0 is not associated with hardware IRQ #0 in legacy IRQ domains.
  Introduce macro XTENSA_PIC_LINUX_IRQ for static translation of xtensa
  PIC hardware IRQ # to linux IRQ #. Use this macro in XTFPGA platform
  data definitions.

  This fixes inability to use hardware IRQ #0 in configurations that don't
  use device tree and allows for non-identity mapping between linux IRQ #
  and hardware IRQ #.

• 41a83e06e   irqchip: Prepare for local stub header removal ... Browse Code »

  The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so
  the local irqchip.h became an empty shell, which solely includes
  include/linux/irqchip.h

  Include the global header in all irqchip drivers instead of the local
  header, so we can remove it.

• cbd1de2e8   xtensa: move built-in PIC to drivers/irqchip ... Browse Code »

  Extract xtensa built-in interrupt controller implementation from
  xtensa/kernel/irq.c and move it to other irqchips, providing way to
  instantiate it from the device tree.
