Subject: [PATCH 0/9] hw: Convert simple devices from SysBus to QDev
Date: Mon, 9 Jan 2023 10:26:08 +0100 [thread overview]
Message-ID: <20230109092617.80224-1-philmd@linaro.org> (raw)
Various simple devices (usually GPIO related) don't access
the 'system bus': no IRQ lines / memory regions exposed via
the SysBus API, no memory region mapped.
To reduce complexity, remove the sysbus onion layer from
these devices.
Introduce the qdev_create_simple() helper similar to the
pattern used for other device creation helpers:
$ git grep _create_simple include/
include/hw/i2c/i2c.h:175:I2CSlave *i2c_slave_create_simple(I2CBus *bus, const char *name, uint8_t addr);
include/hw/isa/isa.h:86:ISADevice *isa_create_simple(ISABus *bus, const char *name);
include/hw/misc/led.h:93:LEDState *led_create_simple(Object *parentobj,
include/hw/pci/pci.h:735:PCIDevice *pci_create_simple_multifunction(PCIBus *bus, int devfn,
include/hw/pci/pci.h:738:PCIDevice *pci_create_simple(PCIBus *bus, int devfn, const char *name);
include/hw/sysbus.h:100:static inline DeviceState *sysbus_create_simple(const char *name,
include/hw/usb.h:505:USBDevice *usb_create_simple(USBBus *bus, const char *name);
