Cover letter [PATCH v7 0/7] Initial Device Tree support for S3C64xx

Quoted 88 lines · Tomasz Figa

This series adds Device Tree support for Samsung S3C64xx SoC series.
It fixes several problems preventing from booting an S3C64xx-based system using Device Tree, adds all the infrastructure for Device Tree-based board support, including mach-s3c64xx-dt and dts include files for S3C64xx SoCs, and basic device tree source for FriendlyARM Mini6410 and SAMSUNG SMDK6410 boards.
Current support is somewhat limite, but should be fine as a start and will be extended in future, hopefully with help of S3C64xx board maintainers.
Depends on:
- [PATCH v2 0/8] Common Clock Framework support for Samsung S3C64xx
    http://thread.gmane.org/gmane.linux.usb.general/90493
On Samsung S3C6410-based Mini6410 and SMDK6410 boards:
Tested-by Tomasz Figa<[email protected]>
Changes since v6:
- Rebased onto current for-next branch of Kgene's tree,
- Dropped the idea of .init_platform() machine callback,
- Added support for i2c controllers,
- Replaced separate apb and ahb nodes with a single common soc node,
- Updated cpus node according to CPU bindings,
- Updated fixed rate clock nodes to use generic bindings,
- Added support for PWM buzzer and I2C EEPROM on Mini6410 board,
- Simplified the condition of skipping legacy GPIO initialization.
Changes since v5:
- Rebased onto current for-next branch of Kgene's tree,
- Added support for new Common Clock Framework based clock driver,
- Introduced hierarchical structure of device nodes (representing physical AHB and APB buses),
- Bypassed most of legacy initialization when booting with DT,
- Used preprocessor macros in dts files to improve readabilty,
- Added support for SMDK6410 board.
Changes since v4:
- Rebased onto current for-next branch of Kgene's tree
- Added support for pinctrl (driver merged through pinctrl tree)
- Added labels to all nodes that can be overridden from board dts
- Modified board dts to use the&label syntax to reference device nodes
Changes since v3:
- Rebased onto current for-next branch of Kgene's tree
- Updated timer node for next version of samsung-time patches
- Replaced local s3c64xx_dt_init_irq with irqchip_init
Changes since v2:
- Updated timer node for next version of samsung-time patches
Changes since v1:
- Dropped two VIC-related patches that are no longer necessary
- Added Device Tree-based instantation of system timers
- Corrected VIC interrupt specifiers
- Adjusted CPU compatible values and dropped @id

Nice, applied this whole series.

Thanks,
