Subject: [PATCH 0/5] virtio: Parse virtio-device nodes from DT
Date: Tue, 13 Jul 2021 16:20:29 +0530 [thread overview]
Message-ID: <cover.1626173013.git.viresh.kumar@linaro.org> (raw)
Hi,
Currently the DT only provides support for following node types for virtio-mmio
nodes:
virtio_mmio@a000000 {
dma-coherent;
interrupts = <0x00 0x10 0x01>;
reg = <0x00 0xa000000 0x00 0x200>;
compatible = "virtio,mmio";
};
And each virtio-mmio corresponds to a virtio-device. But there is no way for
other users in the DT to show their dependency on virtio devices.
This patchset provides that support.
The first patch update virtio,mmio bindings to allow for device subnodes to be
present and the second patch updates the virtio-mmio driver to update the
of_node.
Other patches add bindings for i2c and gpio virtio devices (they have some
dependencies, mentioned in the patches).
Tested on x86 with qemu for arm64.
