Subject: [PATCH v2 0/4] irqchip: lpc32xx: add LPC32xx irqchip driver
Date: Mon, 25 Apr 2016 03:59:50 +0300 [thread overview]
Message-ID: <1461545990-25560-1-git-send-email-vz@mleia.com> (raw)
The change replaces legacy NXP LPC32xx irqchip driver with a new one.
Legacy LPC32xx interrupt controller driver was broken since commit
76ba59f8366f ("genirq: Add irq_domain-aware core IRQ handler"), which
requires a private interrupt handler, otherwise any fired SIC1 generated
interrupt (mapped to MIC hwirq 0) breaks the kernel with the message
"unexpected IRQ trap at vector 00".
Summary of changes from v1 to v2:
* 2 of 10 from v1 changes are found in v4.6 and thus skipped from this
series,
* removed all changes related to optional property 'wakeup-source',
which will be needed later on to support interrupts as wakeup sources,
* removed introduced optional property 'interrupt-controller-name',
* moved DTS changes after new driver, new driver alone used with
old DTS allows to boot LPC32xx boards,
* added a change which actually removes legacy driver,
* improvements in the driver based on a review findings from Marc.
* minor improvements all over the code.
v1 of the changeset can be found here:
