Post one, then the second one based on the previous one (and so on if multiple steps). Anyway, for now I adapted this series on top of your "malta: Fix PCI IRQ levels" series and queued to mips. Thanks, Phil.

Hi Phil, I'm sorry to have caused you issues with my two patch series. In hindsight I should have communicated the merge conflict beforehand. I didn't because I considered it a special case where two logically independent series happened to be created by the same person. Now I know that communicating it earlier had allowed us to find a solution beforehand. After all, I'm more than happy helping out to accellerate integration of my patches. Anyway, thanks for having picked this up and also thanks a lot for your steady stream of motivating review comments! Best regards, Bernhard > >Thanks, > >Phil.
v3: * Use DEFINE_PROP_UINT8 / uint8_t for new IRQ properties. (Philippe) * Use "%u" format when printing maximum allowed IRQ number in error messages. (Philippe) * Use object_property_get_uint() in pnv.c. (Philippe) * Squash cleanup patches (7-22) into "Inline and remove one-line isa_init_irq()" (Philippe) * Mention in the commit message of patch 1 that mc146818rtc has its IRQ number now displayed in the human monitor. Since the IRQ numbers of the other "QOM'ified" devices were already displayed I've only adapted this commit message. (Philippe) v2: * The newly QOM'ified devices now report an error to the user in their realize functions if the configured IRQ number is greater than 15. (PMM) v1: The IRQ attributes of ISADevice are hardcoded to support up to two IRQs per device which creates an artificial limit. By not having the attributes in the first place, this limitation can be avoided altogether. The IRQ attributes are mostly used for printing ('info qtree') and there is one user, hw/ppc/pnv, to use the attributes directly. As it turns out, the printing is redundant if the IRQ numbers are exposed as QOM properties and hw/ppc/pnv can be easily ported away. The patch series is structured as follows: Patch 1-3 QOM'ify the last devices which rely on printing their IRQ numbers via the ISADevice attributes. Patch 4 and 5 remove the last users of the ISADevice attributes such that they can be removed in patch 6. The remainder of the patch series is cleanup. Patch 6 turns isa_init_irq() into a trivial wrapper for isa_get_irq(). That is, the former function becomes redundant. All users are therefore converted to use isa_get_irq() directly. Finally, the last patch removes the now unused isa_init_irq().
