[PATCH v2 0/3] irqchip/sg2042-msi: Set irq type according to DT configuration
Posted by Chen Wang 1 month, 1 week ago
From: Chen Wang <unicorn_wang@outlook.com>

The original MSI interrupt type was hard-coded, which was not a good idea.
Now it is changed to read the device tree configuration and then set the
interrupt type.

This patchset is based on irq/drivers branch of tip.

---

Changes in v2:
  The patch series is based on irq/drivers branch of tip.

  Reverted the change to obtain params of "msi-ranges"; it's better not to
  assume the value of "#interrupt-cells" is 2, even though it's known to be
  the case. Thanks to Inochi for the comments.

Changes in v1:
  The patch series is based on irq/drivers branch of tip. You can simply review
  or test the patches at the link [1].
