  • d86aaca9c   irqchip/qcom: Fix check for spurious interrupts ... Browse Code »

    commit 1bc2463cee92ef0e2034c813d5e511adeb58b5fd upstream.

    When the interrupts for a combiner span multiple registers it must be
    checked if any interrupts have been asserted on each register before
    checking for spurious interrupts.

    Checking each register seperately leads to false positive warnings.

  • f0d564230   irqchip/qcom: Fix u32 comparison with value less than zero ... Browse Code »

    [ Upstream commit e9990d70e8a063a7b894c5cbb99f630a0f41200d ]

    The comparison of u32 nregs being less than zero is never true since
    nregs is unsigned. Fix this by making nregs a signed integer.

    Driver for interrupt combiners in the Top-level Control and Status
    Registers (TCSR) hardware block in Qualcomm Technologies chips.

    An interrupt combiner in this block combines a set of interrupts by
    OR'ing the individual interrupt signals into a summary interrupt
    signal routed to a parent interrupt controller, and provides read-
    only, 32-bit registers to query the status of individual interrupts.
    The status bit for IRQ n is bit (n % 32) within register (n / 32)
    of the given combiner. Thus, each combiner can be described as a set
    of register offsets and the number of IRQs managed.
