dm: core: Add support for writing u32 with ofnode

2022-08-12T12:14:24Z

Add a new function to write an integer to an ofnode (live tree or flat tree). Signed-off-by: Simon Glass

dm: core: Allow writing to a flat tree with ofnode

2022-08-12T12:14:24Z

In generally it is not permitted to implement an ofnode function only for flat tree or live tree. Both must be supported. Also the code for live tree access should be in of_access.c rather than ofnode.c which is really just for holding the API-conversion code. Update ofnode_write_prop() accordingly and fix the test so it can work with flat tree too. Signed-off-by: Simon Glass

dm: core: Tidy up ofnode-writing test

2022-08-12T12:14:24Z

Update this test to use the livetree flag so that special check can be avoided. Also drop a few blank lines. Signed-off-by: Simon Glass

dm: core: Swap parameters of ofnode_write_prop()

2022-08-12T12:14:24Z

It is normal for the length to come after the value in libfdt. Follow this same convention with ofnode. Signed-off-by: Simon Glass

dm: core: Move ofnode-writing test to ofnode

2022-08-12T12:14:24Z

This fits better in the ofnode tests, so move it. Signed-off-by: Simon Glass

dm: core: Introduce support for multiple trees

2022-08-12T12:14:23Z

At present ofnode only works with a single device tree, for the most part. This is the control FDT used by U-Boot. When booting an OS we may obtain a different device tree and want to modify it. Add some initial support for this into the ofnode API. Note that we don't permit aliases in this other device tree, since the of_access implementation maintains a list of aliases collected at start-up. Also, we don't need aliases to do fixups in the other FDT. So make sure that flat tree and live tree processing are consistent in this area. Signed-off-by: Simon Glass

net: introduce helpers to get PHY interface mode from a device/ofnode

2022-04-10T05:44:12Z

Add helpers ofnode_read_phy_mode() and dev_read_phy_mode() to parse the "phy-mode" / "phy-connection-type" property. Add corresponding UT test. Use them treewide. This allows us to inline the phy_get_interface_by_name() into ofnode_read_phy_mode(), since the former is not used anymore.

net: introduce helpers to get PHY ofnode from MAC

2022-04-10T05:44:12Z

Add helpers ofnode_get_phy_node() and dev_get_phy_node() and use it in net/mdio-uclass.c function dm_eth_connect_phy_handle(). Also add corresponding UT test. This is useful because other part's of U-Boot may want to get PHY ofnode without connecting a PHY. Signed-off-by: Marek Behún Reviewed-by: Ramon Fried Reviewed-by: Simon Glass

dm: Fix OF_BAD_ADDR definition

2022-01-25T19:36:10Z

When OF_LIVE flag is enabled on a 64 bits platform, there is an issue when dev_read_addr() is called and need to perform an address translation using __of_translate_address(). In case of error, __of_translate_address() return's value is OF_BAD_ADDR (wich is defined in include/dm/of.h to ((u64)-1) = 0xffffffffffffffff). The return value of dev_read_addr() is often compared to FDT_ADDR_T_NONE which is defined as (-1U) = 0xffffffff. In this case the comparison is always false. To fix this issue, define FDT_ADDR_T_NONE to (ulong)(-1) in case of AARCH64. Update accordingly related tests. Signed-off-by: Patrice Chotard Reviewed-by: Simon Glass

dm: core: Add a way to obtain a string list

2021-11-28T23:51:51Z

At present we support reading a string list a string at a time. Apart from being inefficient, this makes it impossible to separate reading of the devicetree into the of_to_plat() method where it belongs, since any code which needs access to the string must read it from the devicetree. Add a function which returns the string property as an array of pointers to the strings, which is easily used by clients. Signed-off-by: Simon Glass
