/* |
|
* 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() |
