Often a register contains control field so that change in this field causes linear change in the controlled property. It is not a rare case that user wants to give 'meaningful' control values and driver needs to convert them to register field values. Even more often user wants to 'see' the currently set value - again in meaningful units - and driver needs to convert the values it reads from register to these meaningful units. Examples of this include: - regulators, voltage/current configurations - power, voltage/current configurations - clk(?) NCOs and maybe others I can't think of right now. Provide a linear_range helper which can do conversion from user value to register value 'selector'. The idea here is stolen from regulator framework and patches refactoring the regulator helpers to use this are following. Current implementation does not support inversely proportional ranges but it might be useful if we could support also inversely proportional ranges?

I deeply dislike unit-tests.

It is tempting to think that + * walking through all the possible execution branches will nail down 100% of + * bugs. This may lead to ideas about demands to get certain % of "test + * coverage" - measured as line coverage. And that is one of the worst things + * you can do. + * + * Ask people to provide line coverage and they do. I've seen clever tools + * which generate test cases to test the existing functions - and by default + * these tools expect code to be correct and just generate checks which are + * passing when ran against current code-base. Run this generator and you'll get + * tests that do not test code is correct but just verify nothing changes. + * Problem is that testing working code is pointless. And if it is not + * working, your test must not assume it is working. You won't catch any bugs + * by such tests. What you can do is to generate a huge amount of tests. + * Especially if you were are asked to proivde 100% line-coverage x_x. So what + * does these tests - which are not finding any bugs now - do? + * + * They add inertia to every future development. I think it was Terry Pratchet + * who wrote someone having same impact as thick syrup has to chronometre. + * Excessive amount of unit-tests have this effect to development. If you do + * actually find _any_ bug from code in such environment and try fixing it... + * ...chances are you also need to fix the test cases. In sunny day you fix one + * test. But I've done refactoring which resulted 500+ broken tests (which had + * really zero value other than proving to managers that we do do "quality")... + * + * After this being said - there are situations where UTs can be handy. If you + * have algorithms which take some input and should produce output - then you + * can implement few, carefully selected simple UT-cases which test this. I've + * previously used this for example for netlink and device-tree data parsing + * functions. Feed some data examples to functions and verify the output is as + * expected. I am not covering all the cases but I will see the logic should be + * working. + * + * Here we also do some minor testing. I don't want to go through all branches + * or test more or less obvious things - but I want to see the main logic is + * working. And I definitely don't want to add 500+ test cases that break when + * some simple fix is done x_x.

Please note, This patch needs to go in before linear_ranges is used by regulators because the struct linear_range becomes visible to this driver via the BD70528 MFD headers which include the regulator headers.

First one when battery is almost empty is often called as trickle-charge. Last state when battery has been "woken up" is usually called as fast-charge. In addition to this some chargers have a 'middle state' which ROHM BD99954 data-sheet describes as pre-charge. Some batteries can benefit from this 3-phase charging [citation needed]. Introduce trickle-charge-current-microamp so that batteries can give charging current limit for all three states. - precharge-upper-limit-microvolt: When battery voltage has reached certain limit we change from trickle-charge to next charging state (pre-charge for BD99954). Allow battery to specify this limit. - re-charge-voltage-microvolt: Allow giving a battery specific voltage limit for chargers which can automatically re-start charging when battery has discharghed down to this limit. - over-voltage-threshold-microvolt Allow specifying voltage threshold after which the battery is assumed to be faulty.
