From 89f68302cacaa41330959420d7329b7c89afdd88 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Fri, 25 Sep 2020 09:41:14 +0200 Subject: dm: add cells_count parameter in *_count_phandle_with_args The cell_count argument is required when cells_name is NULL. This patch adds this parameter in live tree API - of_count_phandle_with_args - ofnode_count_phandle_with_args - dev_count_phandle_with_args This parameter solves issue when these API is used to count the number of element of a cell without cell name. This parameter allow to force the size cell. For example: count = dev_count_phandle_with_args(dev, "array", NULL, 3); Signed-off-by: Patrick Delaunay Reviewed-by: Simon Glass --- include/dm/of_access.h | 4 +++- include/dm/ofnode.h | 3 ++- include/dm/read.h | 8 +++++--- 3 files changed, 10 insertions(+), 5 deletions(-) (limited to 'include') diff --git a/include/dm/of_access.h b/include/dm/of_access.h index 2fa65c9332e..cc382b1671c 100644 --- a/include/dm/of_access.h +++ b/include/dm/of_access.h @@ -450,6 +450,7 @@ int of_parse_phandle_with_args(const struct device_node *np, * @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 + * @cells_count: Cell count to use if @cells_name is NULL * @return number of phandle found, -ENOENT if * @list_name does not exist, -EINVAL if a phandle was not found, * @cells_name could not be found, the arguments were truncated or there @@ -460,7 +461,8 @@ int of_parse_phandle_with_args(const struct device_node *np, * */ int of_count_phandle_with_args(const struct device_node *np, - const char *list_name, const char *cells_name); + const char *list_name, const char *cells_name, + int cells_count); /** * of_alias_scan() - Scan all properties of the 'aliases' node diff --git a/include/dm/ofnode.h b/include/dm/ofnode.h index 98c64fece30..4b7af370560 100644 --- a/include/dm/ofnode.h +++ b/include/dm/ofnode.h @@ -556,12 +556,13 @@ int ofnode_parse_phandle_with_args(ofnode node, const char *list_name, * @node: device tree node containing a list * @list_name: property name that contains a list * @cells_name: property name that specifies phandles' arguments count + * @cells_count: Cell count to use if @cells_name is NULL * @return number of phandle on success, -ENOENT if @list_name does not * exist, -EINVAL if a phandle was not found, @cells_name could not * be found. */ int ofnode_count_phandle_with_args(ofnode node, const char *list_name, - const char *cells_name); + const char *cells_name, int cell_count); /** * ofnode_path() - find a node by full path diff --git a/include/dm/read.h b/include/dm/read.h index 67db94adfc1..0585eb12281 100644 --- a/include/dm/read.h +++ b/include/dm/read.h @@ -429,12 +429,14 @@ int dev_read_phandle_with_args(const struct udevice *dev, const char *list_name, * @dev: device whose node containing a list * @list_name: property name that contains a list * @cells_name: property name that specifies phandles' arguments count + * @cells_count: Cell count to use if @cells_name is NULL * @Returns number of phandle found on success, on error returns appropriate * errno value. */ int dev_count_phandle_with_args(const struct udevice *dev, - const char *list_name, const char *cells_name); + const char *list_name, const char *cells_name, + int cell_count); /** * dev_read_addr_cells() - Get the number of address cells for a device's node @@ -880,10 +882,10 @@ static inline int dev_read_phandle_with_args(const struct udevice *dev, } static inline int dev_count_phandle_with_args(const struct udevice *dev, - const char *list_name, const char *cells_name) + const char *list_name, const char *cells_name, int cell_count) { return ofnode_count_phandle_with_args(dev_ofnode(dev), list_name, - cells_name); + cells_name, cell_count); } static inline int dev_read_addr_cells(const struct udevice *dev) -- cgit v1.3.1
