      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()
