2008-01-26[ARM] pxa: make MFP configuration processor independenteric miao
There are two reasons for making the MFP configuration to be processor independent, i.e. removing the relationship of configuration bits with actual MFPR register settings: 1. power management sometimes requires the MFP to be configured differently when in run mode or in low power mode 2. for future integration of pxa{25x,27x} GPIO configurations The modifications include: 1. introducing of processor independent MFP configuration bits, as defined in [include/asm-arm/arch-pxa/mfp.h]: bit 0.. 9 - MFP Pin Number (1024 Pins Maximum) bit 10..12 - Alternate Function Selection bit 13..15 - Drive Strength bit 16..18 - Low Power Mode State bit 19..20 - Low Power Mode Edge Detection bit 21..22 - Run Mode Pull State and so on, 2. moving the processor dependent code from mfp.h into mfp-pxa3xx.h 3. cleaning up of the MFPR bit definitions 4. mapping of processor independent MFP configuration into processor specific MFPR register settings is now totally encapsulated within pxa3xx_mfp_config() 5. using of "unsigned long" instead of invented type of "mfp_cfg_t" according to Documentation/CodingStyle Chapter 5, usage of this in platform code will be slowly removed in later patches Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-26[ARM] pxa: remove un-used pxa3xx_mfp_set_xxx() functionseric miao
pxa3xx_mfp_set_xxx() functions are originally provided for overwriting MFP configurations performed by pxa3xx_mfp_config(), the usage of such a dirtry trick is not recommended, since there is currently no user of these functions, they are safely removed Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
