[PATCH v5 0/6] arm: Add basic support for Mediatek Cortex-A7 SoCs

Fifth round for the Mediatek basic support patches.

I changed the compatible string to the first SoC known which integrates the
timer.

I kept the minimal machine file. The debate about it is ongoing and up to now
minimal machine files are not removed [0]. This file will probably disappear
when Robs patch [1] or a similar approach gets accepted.

This patch set adds basic support for the Mediatek Cortex-A7 SoCs.
Support is quite basic, as the only component working up to now are the
timers.

The patch series is build against torvalds/master tree.

Changes for v5:
1. Clocksource timer
- Change the compatible string to mt6577

2. Timer DT bindings
- Change compatible string to mt6577

Changes for v4:
1. Clocksource timer
- use cpu_possible_mask

2. Timer DT bindings
- Delete comments about the frequency of the clocks
- Add clock-names for the input clocks

3. Basic SoC support
- add clock-names for the timer
- rename the label of the clocks nodes

Changes for v3:
1. Clocksource timer
- Set cpu_mask_all and irq in clock_event_device
- Use device private structure for driver specific values

2. Timer DT bindings
- Define order of the clock phandles
- Fix typos

3. Basic SoC support
- DTS: set gic to a15-gic
- DTS: order by physical address
- Remove call to dt_init function

Changes for v2:
1. Clocksource timer
- Delete unused parts for sched_clock_source
- Use irq_request instead of setup_irq
- Remove unused SMP parts
- Fix some style issues
- use of_address_to resource and request_mem_region
- delete use of named clock
- select CLKSRC_MMIO in driver Kconfig

2. DT bindings
- delete named clock bindings

3. Basic SoC support
- Clean-up Kconfig
- Add documentation of the SoC compatible property
- DTS: rename SoC file to mt6589.dts
- DTS: Delete not present cache controller
- DTS: Add missing GICv2 properties
- DTS: Change clock names
- DTS: Add Aquaris5 board

4. Add earlyprintk
- patch droped until serial driver is available

5. Add support for Aquaris5 mobile phone
