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