equals to IMX_SC_R_DMA_2_CH5, so there should be two entries in

pmdomain: Rename the genpd subsystem to pmdomain 2023-09-13T09:09:21+00:00 Ulf Hansson ulf.hansson@linaro.org 2023-09-12T22:11:27+00:00 e2ad626f8f409899baf1bf192d0533a851128b19 It has been pointed out that naming a subsystem "genpd" isn't very self-explanatory and the acronym itself that means Generic PM Domain, is known only by a limited group of people. In a way to improve the situation, let's rename the subsystem to pmdomain, which ideally should indicate that this is about so called Power Domains or "PM domains" as we often also use within the Linux Kernel terminology.

It has been pointed out that naming a subsystem "genpd" isn't very
self-explanatory and the acronym itself that means Generic PM Domain, is
known only by a limited group of people.

In a way to improve the situation, let's rename the subsystem to pmdomain,
which ideally should indicate that this is about so called Power Domains or
"PM domains" as we often also use within the Linux Kernel terminology.
