| * ABSTRACT: |
| * |
| * The PXA270 processor comes with a bunch of hardware on its silicon. |
| * Not all of this hardware can be used at the same time and not all |
| * is routed to module's connectors. Also it depends on the baseboard, what |
| * kind of hardware can be used in which way. |
| * -> So this file supports the main devices on the CPU card only! |
| * Refer pcm990-baseboard.c how to extend this features to get a full |
| * blown system with many common interfaces. |
| * |
| * The PCM-027 supports the following interfaces through its connectors and |
| * will be used in pcm990-baseboard.c: |
| * |
| * - LCD support |
| * - MMC support |
| * - IDE/CF card |
| * - FFUART |
| * - BTUART |
| * - IRUART |
| * - AC97 |
| * - SSP |
| * - SSP3 |
| * |
| * Claimed GPIOs: |
| * GPIO0 -> IRQ input from RTC |
| * GPIO2 -> SYS_ENA*) |
| * GPIO3 -> PWR_SCL |
| * GPIO4 -> PWR_SDA |
| * GPIO5 -> PowerCap0*) |
| * GPIO6 -> PowerCap1*) |
| * GPIO7 -> PowerCap2*) |
| * GPIO8 -> PowerCap3*) |
| * GPIO15 -> /CS1 |
| * GPIO20 -> /CS2 |
| * GPIO21 -> /CS3 |
| * GPIO33 -> /CS5 network controller select |
| * GPIO52 -> IRQ from network controller |
| * GPIO78 -> /CS2 |
| * GPIO80 -> /CS4 |
| * GPIO90 -> LED0 |
| * GPIO91 -> LED1 |
| * GPIO114 -> IRQ from CAN controller |
| * GPIO117 -> SCL |
| * GPIO118 -> SDA |
| * |
| * *) CPU internal use only |
