Detailed Description

Macro Definition Documentation

RA_CGC_CLK_DIV

#define RA_CGC_CLK_DIV	(		clk,
			prop,
			default_value )

#include <zephyr/drivers/clock_control/renesas_ra_cgc.h>

Value:

UTIL_CAT(RA_CGC_DIV_, DT_NODE_FULL_NAME_UPPER_TOKEN(clk))                                  \
(RA_CGC_PROP_HAS_STATUS_OKAY_OR(clk, prop, default_value))

Helper to compute a clock divider.

This macro expands to a RA_CGC_DIV_* prefix combined with a devicetree value.

RA_CGC_CLK_SRC

#define RA_CGC_CLK_SRC

(

node_id

)

#include <zephyr/drivers/clock_control/renesas_ra_cgc.h>

Value:

COND_CODE_1(DT_NODE_HAS_STATUS(node_id, okay), \
        (UTIL_CAT(BSP_CLOCKS_SOURCE_, DT_NODE_FULL_NAME_UPPER_TOKEN(node_id))), \
        (BSP_CLOCKS_CLOCK_DISABLED))

Helper to get clock source form device tree.

Expands to a BSP_CLOCKS_SOURCE_* constant when the node is enabled, or BSP_CLOCKS_CLOCK_DISABLED otherwise.

RA_CGC_PROP_HAS_STATUS_OKAY_OR

#define RA_CGC_PROP_HAS_STATUS_OKAY_OR	(		node_id,
			prop,
			default_value )

#include <zephyr/drivers/clock_control/renesas_ra_cgc.h>

Value:

COND_CODE_1(DT_NODE_HAS_STATUS(node_id, okay), \
        (DT_PROP(node_id, prop)), (default_value))

Conditional property getter based on devicetree status.

Returns the value of a devicetree property if the node is marked as okay. Otherwise, the provided default value is used.
