v3 cover SPEAr DT support updates

Hello,

This patchset updates DT support for SPEAr3xx and 6xx. It has following changes:
- updates DT support Mainly for SPEAr3xx family
- updates dma support for SPEAr6xx
- updates defconfig

It has dependency on following patchsets:
- ehci & ohci: http://www.spinics.net/lists/linux-usb/msg60362.html
- rtc: http://lkml.org/lkml/2012/3/26/96
- keyboard: http://www.spinics.net/lists/linux-input/msg19904.html

V2->V3:
- Removed macro for adding entries in auxdata array for ssp and dma
- removed IO_ADDRESS() completely
- Create 16M static mappings instead of 4K mappings
- Don't return error from spear*dt_init() if board doesn't match for padmux
- Config symbols and #ifdef,#endif are not updated for DT
- interrupt-parenti=<&vic> moved to root node.

V1->V2:
- Separate DT_MACHINE_INIT macros are defined per SoC.
- PATCH 1/7 was sent earlier as individual patch, and is now included in this patchset for completeness.
- clock support for ehci and ohci added
- plat data for UART PL011 removed as it is not required
- Minor issues fixed

Viresh Kumar (7):
SPEAr: Use CLKDEV_INIT for defining clk_lookups
SPEAr3xx: Add clock instance of usb hosts - ehci and ohci 0 and 1
SPEAr6xx: Add compilation support for dtbs using 'make dtbs'
SPEAr3xx: Replace printk() with pr_*()
ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture
SPEAr: Add PL080 DMA support for 3xx and 6xx
SPEAr: Update defconfigs

PATCH v3 2/7 SPEAr3xx: Add clock instance of usb hosts - ehci and ohci 0 and 1

In reply to Viresh Kumar

This patch adds following clocks: "usbh.0_clk" and "usbh.1_clk". They are used by ehci and ohci drivers for SPEAr3xx usb host devices.

PATCH v3 3/7 SPEAr6xx: Add compilation support for dtbs using 'make dtbs'

In reply to Viresh Kumar

'make dtbs' compiles all dtbs for a family. For this we need to add entries for all board dtb's in Makefile.boot file. This patch does it.

PATCH v3 4/7 SPEAr3xx: Replace printk() with pr_*()

In reply to Viresh Kumar

For better print logs/messages, it is advisable to use pr_*() routines instead of directly calling printks. This patch removes direct calling of printks for spear3xx.

PATCH v3 5/7 ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture

In reply to Viresh Kumar

This patch adds a generic target for SPEAr3xx machines that can be configured via the device-tree. Currently the following devices are supported via the devicetree:

- VIC interrupts
- PL011 UART
- PL061 GPIO
- PL110 CLCD
- SP805 WDT
- Synopsys DW I2C
- Synopsys DW ethernet
- ST FSMC-NAND
- ST SPEAR-SMI
- ST SPEAR-KEYBOARD
- ST SPEAR-RTC
- ARASAN SDHCI-SPEAR
- SPEAR-EHCI
- SPEAR-OHCI

Other peripheral devices will follow in later patches.

This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of 4K for individual peripherals. This is done to have efficient TLB lookup for any I/O windows that are located closely together. ioremap() on this range will return this mapping only instead of creating another.

PATCH v3 6/7 SPEAr: Add PL080 DMA support for 3xx and 6xx

In reply to Viresh Kumar

Both SPEAr3xx and SPEAr6xx families have one instance of ARM PL080 DMA controller. This patch adds in support for that.

PATCH v3 7/7 SPEAr: Update defconfigs

In reply to Viresh Kumar

Recently device tree support is added for SPEAr3xx & SPEAr6xx and we must upgrade defconfig for that to get compiled. This patches does it.

There are few more rearrangements done in defconfig automatically, when i run make savedefconfig.
