7 * NOTE: the MFPR register bit definitions on PXA168 processor lines are a
8 * bit different from those on PXA3xx. Bit [7:10] are now reserved, which
9 * were SLEEP_OE_N, SLEEP_DATA, SLEEP_SEL and the LSB of DRIVE bits.
11 * To cope with this difference and re-use the pxa3xx mfp code as much as
12 * possible, we make the following compromise:
14 * 1. SLEEP_OE_N will always be programmed to '1' (by MFP_LPM_FLOAT)
15 * 2. DRIVE strength definitions redefined to include the reserved bit10
16 * 3. Override MFP_CFG() and MFP_CFG_DRV()
17 * 4. Drop the use of MFP_CFG_LPM() and MFP_CFG_X()
