| to 266MHz (see data-sheet for more information) |
| |
| |
| Clock |
| ----- |
| |
| The core clock code provides a set of clocks to the drivers, and allows |

| s3c2410 driver in the drivers/mtd/nand/raw directory. |
| |
| |
| USB Host |
| -------- |
| |
| The USB hardware is similar to the S3C2410, with extended clock source |
| control. The OHCI portion is supported by the ohci-s3c2410 driver, and |
| the clock control selection is supported by the core clock code. |
| |
| |
| USB Device |
| ---------- |
| |
| No current support in the kernel |
| |
| |
