9f55342cc2 ARM: dts: s3c64xx: Fix infinite interrupt in soft mode
In soft (no-reboot) mode, the driver self-pings watchdog upon expiration
of an interrupt.  The interrupt has to be cleared, because otherwise
system enters infinite interrupt handling loop.

Use a samsung,s3c6410-wdt compatible to select appropriate quirk for
clearing the watchdog interrupt.

b5acdc38b8 ARM: dts: s3c64xx: Enable watchdog on all S3C64xx boards
Watchdog module does not have external dependencies so it can be safely
enabled in s3c64xx.dtsi thus making it available for all S3C64xx-based
boards.

5e794de514 ARM: dts: Enable PWM node by default for s3c64xx
The PWM block is required for system clock source so it must be always
enabled. This patch fixes boot issues on SMDK6410 which did not have
the node enabled explicitly for other purposes.

Fixes: eeb93d02 ("clocksource: of: Respect device tree node status")

1e64f48ea7 ARM: dts: SAMSUNG: Add aliases of UART nodes
This patch adds alias entries for UART nodes of all SoCs using
samsung-uart compatible UART controllers, so that the dependency on
probe order is removed and deterministic device naming is assured.

4961cfd508 ARM: dts: Add basic dts include files for Samsung S3C64xx SoCs
This patch adds basic device tree definitions for Samsung S3C64xx SoCs.

Since all the SoCs in the series are very similar, the files are created
hierarchically - one file for the whole series and then separate files
for particular SoCs including the common one.
