Tom,

Even if this patch is not applied if considered useless, the one fixing
the clocks (http://patchwork.ozlabs.org/patch/410834/) should be, in my
opinion, as it is essentially a bug fix. Now, for the DRA7xx SoCs,
1) a write to a undefined (or zero) register address is occurring since
   struct member .cm_l4per_i2c5_clkctrl is not initialized, and
2) a 'data abort' exception shall happen if access to I2C5 is tried due
   to lack of the functional clock.

Best regards,
Lubo
