| | | | | | | | | | | | | | | | | | Similar to the device parameter functions also make the globalvar functions more consistent. This also adds support for readonly globalvars and changes several existing globalvars which should really be readonly to readonly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * param: make parameter functions more consistentSascha Hauer2017-04-111-37/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | libgen: implement posix_basenameSascha Hauer2017-04-191-0/+1
| |/ | | | | | | | | | | | | | | | | | | There are two different versions of basename(): The GNU version and the POSIX version. The GNU version never modifies its argument and returns the empty string when path has a trailing slash, and in particular also when it is "/". The POSIX version modifies its argument and thus works properly with strings which have a trailing "/". Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * of: of_path: add of_find_node_by_devpath()Sascha Hauer2017-03-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already have of_find_path_by_node() which finds a device path for a given device node. This is used by the state framework to find its backend path. This path has to be translated back to a device node when Linux is started. The current approach turned out to be too simple: We assumed that the node path is the same in the tree Linux is started with. This is not true in several cases: - partition nodes should have the name "partition@<offset>", but in several trees they have "partition@<num>" - There are two different partition bindings: The legacy binding and the new one with an additional partitions subnode which has a compatible = "fixed-partitions" property. The node path only stays the same when the internal tree uses the same bindings and node names as the tree Linux is started with. To overcome this limitation we create of_find_node_by_devpath() which converts the device path back to a device node. It does so by finding the device node of the hardware device rather than the partition node. It then parses over the partitions in this device node with the known bindings looking for a partition which matches in offset and size to the barebox partition.

| | | | | | | | | | | | | | | | | | We are going to call the of_partition_fixup for regular block devices like MMC/SD aswell. Add a flag to partitions indicating they are instanciated from a on-disk partition table so that they won't be added as device tree partitions during fixup.

| * fs: devfs-core: replace DEVFS_IS_PARTITION flag with pointer to the master cdevSascha Hauer2017-03-311-1/+1

| * mtd: of: Make used partition binding configurableSascha Hauer2017-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | So far we used the legacy partition binding when fixing up the mtd partition nodes. Change this to default to the new binding with a "partitions" submode. Make this behaviour configurable though: This creates a new of_binding device variable for mtd devices. This can be set to: - "new": Use the new partition binding (default) - "legacy": Use the old partition binding - "donttouch": Do not touch the partition node Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The globalvar_add_simple_* functions will fail when a globalvar of the name already exists. This happened when the globalvar was created previously because a corresponding nvvar existed. For this reason we removed the globalvars that have been previously created by nvvar creation (we called these unqualified globalvars). Since we no longer create the corresponding globalvars on nvvar creation this code is no longer needed. Remove it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to have a static array of trigger types which, allows only one led per trigger. While this is enough for panic and heartbeat, it falls short when multiple leds are associated to the default-on trigger. The default-on trigger is used to turn on a led statically from devicetree and may be used multiple times.
