I think people might be reading differences into 'if' and 'depends on' that aren't there, like maybe 'if' being needed to "hide" a symbol, while 'depends on' just adds a dependency. There are no differences between 'if' and 'depends on'. 'if' is just a shorthand for 'depends on'. They work the same when it comes to creating implicit menus too. The way symbols get "hidden" is through their dependencies not being satisfied ('if'/'depends on' get copied up as a dependency on the prompt). Since 'if' and 'depends on' are the same, an 'if' with just a single symbol in it can be replaced with a 'depends on'. IMO, it's best to avoid 'if' there as a style choice too, because it confuses people into thinking there's deep Kconfig magic going on that requires 'if'. Going for 'depends on' can also remove some nested 'if's, which generates nicer symbol information and docs, because nested 'if's really are so simple/dumb that they just add the dependencies from both 'if's to all symbols within. Replace a bunch of single-symbol 'if's with 'depends on' to despam the Kconfig files a bit and make it clearer how things work. Also do some other minor related dependency refactoring. The replacement isn't complete. Will fix up the rest later. Splitting it a bit to make it more manageable. (Everything above is true for choices, menus, and comments as well.) Detected by tweaking the Kconfiglib parsing code. It's impossible to detect after parsing, because 'if' turns into 'depends on'. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>
