[PATCH v4 0/2] Add IAX45 support for RZ/Five SoC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi All,

The IAX45 block on RZ/Five SoC is almost identical to the IRQC bock found
on the RZ/G2L family of SoCs.

IAX45 performs various interrupt controls including synchronization for the
external interrupts of NMI, IRQ, and GPIOINT and the interrupts of the
built-in peripheral interrupts output by each module. And it notifies the
interrupt to the PLIC.
- Select 32 TINT from 82 GPIOINT.
- Integration of bus error interrupts from system bus.
- Integration of ECC error interrupts from On-chip RAM.
- Indicate interrupt status. (NMI, IRQ, TINT, integrated bus error
  interrupt and integrated ECC error interrupt)
- Setting of interrupt detection method. (NMI, IRQ and TINT)
- All interrupts are masked by INTMASK.
- Mask function for NMI, IRQ and TINT

This patch series adds support for IAX45 in the IRQC driver and enables
this on RZ/Five SoC.

v3->v4
- Renamed rzg2l_irqc_init_helper -> rzg2l_irqc_common_init
- Moved the locks into callers for (un)mask and (en/dis)able functions
- Collected RB tag from Geert for patch#2

v2->v3
- DTS/I patches dropped from the series as they have been merged into
  renesas-soc tree
- Just using a const from compat string instead of having it in a items
- Added RZ/Five specific irqchip
