+ The driver for the built-in TWI module has been plagued by

+ * Depending on the SOC, each timer may have its own clock and IRQ, or those
+ * may be shared by the whole TC block.
+ *
+ * These TC blocks may have up to nine external pins: TCLK0..2 signals for
+ * clocks or clock gates, and per-timer TIOA and TIOB signals used for PWM
+ * or triggering. Those pins need to be set up for use with the TC block,
+ * else they will be used as GPIOs or for a different controller.
+ *
+ * Although we expect each TC block to have a platform_device node, those
+ * nodes are not what drivers bind to. Instead, they ask for a specific
+ * TC block, by number ... which is a common approach on systems with many
+ * timers. Then they use clk_get() and platform_get_irq() to get clock and
