[00/13] hw: Split RTC devices from hw/timer/ to hw/rtc/

Message

When working on timers, I found it confuse to have RTC devices
mixed in the hw/timer/ directory.

We can see the models use slighly different APIs:

  $ git grep '#include' hw/timer/|cut -d: -f3-|sort|uniq -c|egrep -v '^      1 '|sort -rn
     33 #include "qemu/osdep.h"
     29 #include "hw/irq.h"
     28 #include "qemu/module.h"
     23 #include "migration/vmstate.h"
     21 #include "hw/sysbus.h"
     20 #include "qemu/timer.h"
     20 #include "qemu/main-loop.h"
     17 #include "qemu/log.h"
     14 #include "hw/qdev-properties.h"
     14 #include "hw/ptimer.h"
      9 #include "trace.h"
      7 #include "qapi/error.h"
      5 #include "hw/hw.h"
      3 #include "sysemu/runstate.h"
      3 #include "qemu/error-report.h"
      3 #include "hw/timer/i8254.h"
      2 #include "qemu/bitops.h"
      2 #include "hw/timer/i8254_internal.h"
      2 #include "hw/registerfields.h"
      2 #include "hw/core/cpu.h"
      2 #include "hw/arm/omap.h"
      2 #include "hw/arm/exynos4210.h"

  $ git grep '#include' hw/rtc/|cut -d: -f3-|sort|uniq -c|egrep -v '^      1 '|sort -rn
     11 #include "qemu/osdep.h"
     10 #include "qemu/module.h"
      9 #include "qemu-common.h"
      8 #include "qemu/timer.h"
      8 #include "migration/vmstate.h"
      6 #include "qemu/bcd.h"
      6 #include "hw/irq.h"
      5 #include "sysemu/sysemu.h"
      5 #include "qemu/log.h"
      5 #include "hw/sysbus.h"
      4 #include "trace.h"
      4 #include "hw/qdev-properties.h"
      3 #include "qemu/cutils.h"
      3 #include "hw/i2c/i2c.h"
      2 #include "sysemu/runstate.h"
      2 #include "m48t59-internal.h"
      2 #include "hw/rtc/m48t59.h"
      2 #include "exec/address-spaces.h"

Split the RTC-related files in the new hw/rtc/ directory.

Philippe Mathieu-Daudé (13):
  hw/timer: Compile devices not target-dependent as common object
  hw: Move PL031 device from hw/timer/ to hw/rtc/ subdirectory
  hw: Move MC146818 device from hw/timer/ to hw/rtc/ subdirectory
  hw: Move M48T59 device from hw/timer/ to hw/rtc/ subdirectory
  hw: Move M41T80 device from hw/timer/ to hw/rtc/ subdirectory
  hw: Move sun4v hypervisor RTC from hw/timer/ to hw/rtc/ subdirectory
  hw: Move TWL92230 device from hw/timer/ to hw/rtc/ subdirectory
  hw: Move DS1338 device from hw/timer/ to hw/rtc/ subdirectory
  hw: Move Xilinx ZynqMP RTC from hw/timer/ to hw/rtc/ subdirectory
  hw: Move Exynos4210 RTC from hw/timer/ to hw/rtc/ subdirectory
  hw: Move Aspeed RTC from hw/timer/ to hw/rtc/ subdirectory
  hw/rtc/mc146818: Include mc146818rtc_regs.h a bit less
  hw/rtc/xlnx-zynqmp-rtc: Remove unused "ptimer.h" include
