[PATCH v2 1/4] ARM: dts: s5pv210: aries: Add reserved memory for mfc

[Paweł Chmiel]

THis commit adds memory reservation required by MFC to run.
On S5PV210 both regions needs to be on separate memory banks.
Size of both regions is taken from stock sources.

[PATCH v2 2/4] ARM: dts: s5pv210: aries: Support for more devices present on Aries

[Paweł Chmiel]

From: Jonathan Bakker <xc-racer2@live.ca>

This commit enables following devices present on Aries based phones:
- pwm-vibrator attached to PWM 1
- poweroff support
- Atmel maXTouch touchscreen, connected to i2c2
- Broadcom BCM4329 bluetooth over uart0

Changes from v1:
   - Touchscreen irq pin should have PULL_NONE, since it's already
     pulled up with 2.8v
   - Touchscreen irq should be edge failing (like in vendor sources)

[PATCH v2 4/4] ARM: defconfig: s5pv210: Enable more drivers present on Samsung Aries

[Paweł Chmiel]

This commit enables following drivers:
- i2c support (using s3c2410 driver)
- s5p-jpeg
- s5p-mfc
- exynos drm rotator
- pwm support
- pwm vibrator
- fixed regulator
- syscon poweroff
- Atmel maXTouch touchscreen
- Broadcom BCM4329 bluetooth over uart0
- dma devices (so we can use pl330 dma driver)

Disable DEBUG_LL. It's currently set to uart1, but if we want to use it
on Aries, we would need to switch it to uart2, to get any logs.
