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

Hi,

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
