Subject: [RESEND 0/2] MFD: twl6040-codec: avoid reconfiguring the PLL

Hello Samual,

This series somehow got lost (the original series has been sent back in
November).
It might be too late for 3.3 :(

The following two patch will optimize the PLL configuration code for the
twl6040, so if the requested configuration is the same as the current we simply
skip configuring the PLL (since no change needed).
We can save considerable amount of time in this way (due to avoiding i2c
accesses, and delays dictated by the configuration protocol).

Regards,
Peter
