+ *
+ * Say you have the following clock configuration
+ *
+ * +---+ +---+
+ * |osc| |pll|
+ * +---+ +---+
+ *         ^

+ *     /   |
+ *    /    |
+ * +---+ +---+
+ * |clk| |clk|
+ * +---+ +---+
+ *
+ * But the pll does not have a bypass, so when you configure the pll, the
+ * configuration needs to change to look like
+ *
+ * +---+ +---+
+ * |osc| |pll|
+ * +---+ +---+
+ *   ^
+ *   |\
+ *   | \
+ *   |  \
+ *   |   \
+ *   |    \
+ * +---+ +---+
+ * |clk| |clk|
+ * +---+ +---+
+ *
+ * To set this up, create a bypass clock with bypassee=pll and alt=osc. When
+ * creating the child clocks, set their parent to the bypass clock. After
+ * creating all the children, call k210_bypass_setchildren().
