If it's missing, it is assumed that the phandle -has no arguments. - -Up until now, a nvmem node didn't have any arguments, so all the device -trees haven't any '#*-cells' property. But there is a need for an -additional argument for the phandle, for which we need a '#*-cells' -property. Therefore, we need to support nvmem nodes with and without -this property. - -Signed-off-by: Michael Walle <michael@walle.cc> -Reviewed-by: Rob Herring <robh@kernel.org> -Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> -Link: https://lore.kernel.org/r/20230206134356.839737-10-srinivas.kandagatla@linaro.org -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> ---- - include/linux/of.h | 25 +++++++++++++++++++++++++ - 1 file changed, 25 insertions(+) - ---- a/include/linux/of.h -+++ b/include/linux/of.h -@@ -1157,6 +1157,31 @@ static inline int of_parse_phandle_with_ - } - - /** -+ * of_parse_phandle_with_optional_args() - Find a node pointed by phandle in a list -+ * @np: pointer to a device tree node containing a list -+ * @list_name: property name that contains a list -+ * @cells_name: property name that specifies phandles' arguments count -+ * @index: index of a phandle to parse out -+ * @out_args: optional pointer to output arguments structure (will be filled) -+ * -+ * Same as of_parse_phandle_with_args() except that if the cells_name property -+ * is not found, cell_count of 0 is assumed. -+ * -+ * This is used to useful, if you have a phandle which didn't have arguments -+ * before and thus doesn't have a '#*-cells' property but is now migrated to -+ * having arguments while retaining backwards compatibility. -+ */ -+static inline int of_parse_phandle_with_optional_args(const struct device_node *np, -+ const char *list_name, -+ const char *cells_name, -+ int index, -+ struct of_phandle_args *out_args) -+{ -+ return __of_parse_phandle_with_args(np, list_name, cells_name, -+ 0, index, out_args); -+} -+ -+/** - * of_property_count_u8_elems - Count the number of u8 elements in a property - * - * @np: device node from which the property value is to be read. |
