 * We have to follow a strict procedure when changing the LDB clock source,

 * Things to keep in mind:
 *
 * 1. The current and new parent clock inputs to the mux must be disabled.
 * 2. The default clock input for ldb_di0/1_clk_sel is mmdc_ch1_axi, which
 *    has no CG bit.
 * 3. pll2_pfd2_396m can not be gated if it is used as memory clock.
 * 4. In the RTL implementation of the LDB_DI_CLK_SEL muxes the top four
 *    options are in one mux and the PLL3 option along with three unused
 *    inputs is in a second mux. There is a third mux with two inputs used
 *    to decide between the first and second 4-port mux:
 *
 *    pll5_video_div 0 --|\
 *    pll2_pfd0_352m 1 --| |_
 *    pll2_pfd2_396m 2 --| | `-|\
 *    mmdc_ch1_axi   3 --|/    | |
 *                             | |--
 *    pll3_usb_otg   4 --|\    | |
 *                   5 --| |_,-|/
 *                   6 --| |
 *                   7 --|/
 *
 * The ldb_di0/1_clk_sel[1:0] bits control both 4-port muxes at the same time.
 * The ldb_di0/1_clk_sel[2] bit controls the 2-port mux. The code below
 * switches the parent to the bottom mux first and then manipulates the top
 * mux to ensure that no glitch will enter the divider.
