Macro Definition Documentation

RX_CGC_CLK_SRC

#define RX_CGC_CLK_SRC

(

node_id

)

Value:

        COND_CODE_1(DT_NODE_HAS_STATUS(node_id, okay),                                             \
                    (UTIL_CAT(RX_CLOCKS_SOURCE_, DT_NODE_FULL_NAME_UPPER_TOKEN(node_id))),        \
                    (RX_CLOCKS_CLOCK_DISABLED))

Helper to get clock source form device tree.

Expands to a RX_CLOCKS_SOURCE_* constant when the node is enabled, or RX_CLOCKS_CLOCK_DISABLED otherwise.

RX_CGC_PLL_CLK_SRC

#define RX_CGC_PLL_CLK_SRC

(

node_id

)

Value:

        COND_CODE_1(DT_NODE_HAS_STATUS(node_id, okay),                                             \
                (UTIL_CAT(RX_PLL_CLOCKS_SOURCE_, DT_NODE_FULL_NAME_UPPER_TOKEN(node_id))),        \
                    (RX_CLOCKS_CLOCK_DISABLED))

Helper to get PLL clock source form device tree.

Expands to a RX_PLL_CLOCKS_SOURCE_* constant when the node is enabled, or RX_CLOCKS_CLOCK_DISABLED otherwise.

RX_CGC_PROP_HAS_STATUS_OKAY_OR

#define RX_CGC_PROP_HAS_STATUS_OKAY_OR	(		node_id,
			prop,
			default_value )

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.

RX_IF_CLK_SRC

#define RX_IF_CLK_SRC

(

node_id

)

Value:

        COND_CODE_1(DT_NODE_HAS_STATUS(node_id, okay),\
                        (UTIL_CAT(RX_IF_CLOCKS_SOURCE_, DT_NODE_FULL_NAME_UPPER_TOKEN(node_id))),\
                        (RX_CLOCKS_CLOCK_DISABLED))

Helper to get IF clock source form device tree.

Expands to a RX_IF_CLOCKS_SOURCE_* constant when the node is enabled, or RX_CLOCKS_CLOCK_DISABLED otherwise.

RX_LPT_CLK_SRC

#define RX_LPT_CLK_SRC

(

node_id

)

Value:

        COND_CODE_1(DT_NODE_HAS_STATUS(node_id, okay),\
                        (UTIL_CAT(RX_LPT_CLOCKS_SOURCE_, DT_NODE_FULL_NAME_UPPER_TOKEN(node_id))),\
                        (RX_LPT_CLOCKS_NON_USE))

Helper to get LPT clock source form device tree.

Expands to a RX_LPT_CLOCKS_SOURCE_* constant when the node is enabled, or RX_LPT_CLOCKS_NON_USE otherwise.
