This commit updates the OSC_32K_CLK (secure_32k_clk_src_ck) frequency
from the precise 32kHz frequency (i.e., 32.768 kHz) to the more
accurate frequency of ~34.6 kHz. Actual measured frequencies of the
clock vary from board to board anywhere from 34.4 kHz up to 34.8 kHz.

Uhm, if you have a board specific, accurate value for this clock, you should update it in the board file itself. This definition is going to be used across all the DRA7 / AM57xx boards, which can very likely have different crystal accuracies.

So, NAK.
