114  * Reset a peripheral. This puts it in reset, waits for a delay, then takes
117  * @param periph_id	peripheral to reset
123  * Put a peripheral into or out of reset.
125  * @param periph_id	peripheral to reset
150  * Set the source for a peripheral clock. This plus the divisor sets the
152  * source parameter as it changes for each peripheral.
157  * @param periph_id	peripheral to adjust
166  * @param periph_id	peripheral to adjust
174  * Set the source and divisor for a peripheral clock. This sets the
176  * source parameter as it changes for each peripheral.
181  * @param periph_id	peripheral to adjust
189  * Returns the current parent clock ID of a given peripheral. This can be
193  * @param periph_id	peripheral to query
194  * @return clock ID of the peripheral's current parent clock
199  * Start a peripheral PLL clock at the given rate. This also resets the
200  * peripheral.
202  * @param periph_id	peripheral to start
211  * Returns the rate of a peripheral clock in Hz. Since the caller almost
215  * @param periph_id	peripheral to start
218  * @return clock rate of peripheral in Hz
224  * Adjust peripheral PLL clock to the given rate. This does not reset the
225  * peripheral. If a second stage divisor is not available, pass NULL for
229  * @param periph_id	peripheral to start
254  * @param periph_id	Peripheral ID of UART to enable (e,g, PERIPH_ID_UART1)
259  * Decode a peripheral ID from a device tree node.
261  * This works by looking up the peripheral's 'clocks' node and reading out
262  * the second cell, which is the clock number / peripheral ID.
266  * @return peripheral ID, or PERIPH_ID_NONE if none
293 /* Returns a pointer to the clock source register for a peripheral */
300  * Given a peripheral ID, determine where the mux bits are in the peripheral
307  * @param periph_id     peripheral to query
317  * Given a peripheral ID and clock source mux value, determine the clock_id
318  * of that peripheral's parent.
323  * @param periph_id     peripheral to query
330  * Given a peripheral ID and the required source clock, this returns which
331  * value should be programmed into the source mux for that peripheral.
335  * @param periph_id     peripheral to start
345  * Convert a device tree clock ID to our peripheral ID. They are mostly
350  * @return peripheral ID, or PERIPH_ID_NONE if the clock ID is invalid
373 /* return 1 if a peripheral ID is in range */
