115  * Reset a peripheral. This puts it in reset, waits for a delay, then takes
118  * @param periph_id	peripheral to reset
124  * Put a peripheral into or out of reset.
126  * @param periph_id	peripheral to reset
151  * Set the source for a peripheral clock. This plus the divisor sets the
153  * source parameter as it changes for each peripheral.
158  * @param periph_id	peripheral to adjust
167  * @param periph_id	peripheral to adjust
175  * Set the source and divisor for a peripheral clock. This sets the
177  * source parameter as it changes for each peripheral.
182  * @param periph_id	peripheral to adjust
190  * Returns the current parent clock ID of a given peripheral. This can be
194  * @param periph_id	peripheral to query
195  * @return clock ID of the peripheral's current parent clock
200  * Start a peripheral PLL clock at the given rate. This also resets the
201  * peripheral.
203  * @param periph_id	peripheral to start
212  * Returns the rate of a peripheral clock in Hz. Since the caller almost
216  * @param periph_id	peripheral to start
219  * @return clock rate of peripheral in Hz
225  * Adjust peripheral PLL clock to the given rate. This does not reset the
226  * peripheral. If a second stage divisor is not available, pass NULL for
230  * @param periph_id	peripheral to start
255  * @param periph_id	Peripheral ID of UART to enable (e,g, PERIPH_ID_UART1)
260  * Decode a peripheral ID from a device tree node.
262  * This works by looking up the peripheral's 'clocks' node and reading out
263  * the second cell, which is the clock number / peripheral ID.
267  * @return peripheral ID, or PERIPH_ID_NONE if none
294 /* Returns a pointer to the clock source register for a peripheral */
301  * Given a peripheral ID, determine where the mux bits are in the peripheral
308  * @param periph_id     peripheral to query
318  * Given a peripheral ID and clock source mux value, determine the clock_id
319  * of that peripheral's parent.
324  * @param periph_id     peripheral to query
331  * Given a peripheral ID and the required source clock, this returns which
332  * value should be programmed into the source mux for that peripheral.
336  * @param periph_id     peripheral to start
346  * Convert a device tree clock ID to our peripheral ID. They are mostly
351  * @return peripheral ID, or PERIPH_ID_NONE if the clock ID is invalid
374 /* return 1 if a peripheral ID is in range */
