| 8 | * NOTE: the MFPR register bit definitions on PXA168 processor lines are a |
| 9 | * bit different from those on PXA3xx. Bit [7:10] are now reserved, which |
| 10 | * were SLEEP_OE_N, SLEEP_DATA, SLEEP_SEL and the LSB of DRIVE bits. |
| 11 | * |
| 12 | * To cope with this difference and re-use the pxa3xx mfp code as much as |
| 13 | * possible, we make the following compromise: |
| 14 | * |
| 15 | * 1. SLEEP_OE_N will always be programmed to '1' (by MFP_LPM_FLOAT) |
| 16 | * 2. DRIVE strength definitions redefined to include the reserved bit |
| 17 | * - the reserved bit differs between pxa168 and pxa910, and the |
| 18 | * MFP_DRIVE_* macros are individually defined in mfp-pxa{168,910}.h |
| 19 | * 3. Override MFP_CFG() and MFP_CFG_DRV() |
| 20 | * 4. Drop the use of MFP_CFG_LPM() and MFP_CFG_X() |
