[Qemu-arm] [PATCH v4 0/8] Add support for the Epson RX8900 RTC to the aspeed board

[Alastair D'Silva]

From: Alastair D'Silva <address@hidden>

This patch series adds support for the Epson RX8900 RTC to the
Aspeed board.

The tests use the existing imx25 infrastructure, and some minor
changes have been made to uniquely identify the I2C buses.

Support for named interrupts has been implemented in qtest to
facilitate testing.

Changelog:
v4:
 - Split overloaded patches
 - Fix spelling of Celsius
 - Remove degrees sign from messages
 - Don't force float precision
 - Reformat named interrupt qtest protocol for consistency
 - Minor formatting changes
 - Don't connect the RX8900 INT line to NVIC:22, it should be
   connected to GPIOJ10 on the ASPEED SOC
v3:
 - Add range checks for time components
 - Shorten trace messages
 - Use qemu generated i2c bus names
 - Address style comments from Alexey for rx8900 driver
 - Fix long lines in qtest harness
 - Remove trailing whitespace in hw/arm/pxa
 - Remove stray headers from rx8900 driver
 - Support low voltage detection in rx8900 driver
v2:
 - Avoid using error_report
 - Fix TIE behaviour
 - Move temperature init out of reset, it should not change
   on a soft reset
 - Fix IRQ in test failures
 - Add a NULL check for i2c slave init callbacks, so that we
   no longer need to implement empty init functions.
 - Refactor to use the existing qemu trace infrastructure
 - Move the RX8900 definition into the aspeed machine init
 - It it possible for check_update_interrupt_seconds in the
   rx8900 test to return 6, depending on the alignment with
   the wall clock.
 - Support low voltage detection
