Bit [7:10] are now reserved, which 108c2ecf20Sopenharmony_ci * were SLEEP_OE_N, SLEEP_DATA, SLEEP_SEL and the LSB of DRIVE bits. 118c2ecf20Sopenharmony_ci * 128c2ecf20Sopenharmony_ci * To cope with this difference and re-use the pxa3xx mfp code as much as 138c2ecf20Sopenharmony_ci * possible, we make the following compromise: 148c2ecf20Sopenharmony_ci * 158c2ecf20Sopenharmony_ci * 1. SLEEP_OE_N will always be programmed to '1' (by MFP_LPM_FLOAT) 168c2ecf20Sopenharmony_ci * 2. DRIVE strength definitions redefined to include the reserved bit 178c2ecf20Sopenharmony_ci * - the reserved bit differs between pxa168 and pxa910, and the 188c2ecf20Sopenharmony_ci * MFP_DRIVE_* macros are individually defined in mfp-pxa{168,910}.h 198c2ecf20Sopenharmony_ci * 3. Override MFP_CFG() and MFP_CFG_DRV() 208c2ecf20Sopenharmony_ci * 4.
