[PATCH 0/8] hw/arm: Cleanups around QOM style

[PATCH 0/8] hw/arm: Cleanups around QOM style

[Philippe Mathieu-Daudé]

- Reduce "hw/qdev-properties.h" inclusions
- Open-code various QDev helpers used few times
- Use QOM cast macro when relevant

Philippe Mathieu-Daudé (8):
  hw/gpio/max7310: Simplify max7310_realize()
  hw/char/pl011: Un-inline pl011_create()
  hw/char/pl011: Open-code pl011_luminary_create()
  hw/char/xilinx_uartlite: Expose XILINX_UARTLITE QOM type
  hw/char/xilinx_uartlite: Open-code xilinx_uartlite_create()
  hw/char/cmsdk-apb-uart: Open-code cmsdk_apb_uart_create()
  hw/timer/cmsdk-apb-timer: Remove unused 'qdev-properties.h' header
  hw/intc/armv7m_nvic: Use QOM cast CPU() macro

[PATCH 1/8] hw/gpio/max7310: Simplify max7310_realize()

[Philippe Mathieu-Daudé]

Since &I2C_SLAVE(dev)->qdev == dev, no need to go back and
forth with QOM type casting. Directly use 'dev'.

[PATCH 2/8] hw/char/pl011: Un-inline pl011_create()

[Philippe Mathieu-Daudé]

pl011_create() is only used in DeviceRealize handlers,
not a hot-path. Inlining is not justified.
