    OMAP3+: VC: abstract out channel configuration · 24d3194a
    Kevin Hilman 提交于
    VC channel configuration is programmed based on settings coming from
    the PMIC configuration.
    
    Currently, the VC channel to PMIC mapping is a simple one-to-one
    mapping.  Whenever a VC channel parameter is configured (i2c slave
    addres, PMIC register address, on/ret/off command), the corresponding
    bits are enabled in the VC channel configuration register.
    
    If necessary, the programmability of channel configuration settings
    could be extended to board/PMIC files, however, because this patch
    changes the channel configuration to be programmed based on existing
    values from the PMIC settings, it may not be required.
    
    Also note that starting with OMAP4, where there are more than 2
    channels, one channel is identified as the "default" channel.  When
    any of the bits in the channel config for the other channels are zero,
    it means to use the default channel.  The OMAP4 TRM (at least through
    NDA version Q) is wrong in describing which is the default channel.
    The default channel on OMAP4 is MPU, not CORE as decribed in the TRM.
