However the two are sequential. Your change for #1 looks good and could be split off and good to go as-is, but you remove the _create function without replacing the logic inline, causing a bisectability issue (is it fixed later for kzm.c)? The removal of _create may have to come later, or split to a sep patch that handles kzm.c change. > > - > -static Property imx32_serial_properties[] = { > +static Property imx_serial_properties[] = { explain change of name in commit message. > DEFINE_PROP_CHR("chardev", IMXSerialState, chr), > DEFINE_PROP_END_OF_LIST(), > }; > @@ -369,21 +339,21 @@ static Property imx32_serial_properties[] = { > static void imx_serial_class_init(ObjectClass *klass, void *data) > { > DeviceClass *dc = DEVICE_CLASS(klass); > - SysBusDeviceClass *k = SYS_BUS_DEVICE_CLASS(klass); > > - k->init = imx_serial_init; > + dc->realize = imx_serial_realize; > dc->vmsd = &vmstate_imx_serial; > dc->reset = imx_serial_reset_at_boot; > - set_bit(DEVICE_CATEGORY_INPUT, dc->categories); > dc->desc = "i.MX series UART"; > - dc->props = imx32_serial_properties; > + dc->props = imx_serial_properties; > + set_bit(DEVICE_CATEGORY_INPUT, dc->categories); do you need to reorder statements? > } > > static const TypeInfo imx_serial_info = { > - .name = TYPE_IMX_SERIAL, > - .parent = TYPE_SYS_BUS_DEVICE, > - .instance_size = sizeof(IMXSerialState), > - .class_init = imx_serial_class_init, > + .name = TYPE_IMX_SERIAL, > + .parent = TYPE_SYS_BUS_DEVICE, > + .instance_size = sizeof(IMXSerialState), > + .instance_init = imx_serial_init, > + .class_init = imx_serial_class_init, > }; > > static void imx_serial_register_types(void) > diff --git a/include/hw/arm/imx.h b/include/hw/arm/imx.h > index ea9e093..c39f112 100644 > --- a/include/hw/arm/imx.h > +++ b/include/hw/arm/imx.h > @@ -11,8 +11,6 @@ > #ifndef IMX_H > #define IMX_H > > -void imx_serial_create(int uart, const hwaddr addr, qemu_irq irq); > - This would also go in the later patch.
