Subject: [PATCH v2 0/3] PCI: Add legacy interrupt support in pci-j721e
Date: Wed, 4 Aug 2021 18:59:09 +0530 [thread overview]
Message-ID: <20210804132912.30685-1-kishon@ti.com> (raw)
Patch series adds support for legacy interrupt in pci-j721e. There are
two HW implementations of legacy interrupt controller, one specific to
J721E and the other for J7200/AM64.
In both these implementations, the legacy interrupt is connect to pulse
interrupt of GIC and level to pulse is handled by configuring EOI
register. EOI to convert level to pulse is broken in J721E due to an
errata but is functional in J7200.
v1 of the patch series can be found @ [1]
Patch series is created on top of [2]
Changes from v1:
1) Only the legacy interrupt specific part is sent as part of this
series. Rest are split and sent as a separate series [2]
2) Created irq_chip for legacy interrupt and used it's ops for enabling,
disabling the interrupts.
