/*
 * 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 bit10
 * 3. Override MFP_CFG() and MFP_CFG_DRV()
 * 4. Drop the use of MFP_CFG_LPM() and MFP_CFG_X()
