| 2026-02-04 | leds: expresswire: Fix chip state breakage | Duje Mihanović | |
| It is possible to put the KTD2801 chip in an unknown/undefined state by changing the brightness very rapidly (for example, with a brightness slider). When this happens, the brightness is stuck on max and cannot be changed until the chip is power cycled. Fix this by disabling interrupts while talking to the chip. While at it, make expresswire_power_off() use fsleep() and also unexport some functions meant to be internal.

| 2024-12-02 | module: Convert symbol namespace to string literal | Peter Zijlstra | |
| Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

| 2024-03-07 | leds: Introduce ExpressWire library | Duje Mihanović | |
| The ExpressWire protocol is shared between at least KTD2692 and KTD2801 with slight differences such as timings and the former not having a defined set of pulses for enabling the protocol (possibly because it does not support PWM unlike KTD2801). Despite these differences the ExpressWire handling code can be shared between the two, so in preparation for adding KTD2801 support introduce a library implementing this protocol.
