Basically separate the logic from the data and all is well. + + Part 6 - Disabling clock gating of unused clocks + +Sometimes during development it can be useful to be able to bypass the +default disabling of unused clocks. For example, if drivers aren't enabling +clocks properly but rely on them being on from the bootloader, bypassing +the disabling means that the driver will remain functional while the issues +are sorted out. + +To bypass this disabling, include "clk_ignore_unused" in the bootargs to the +kernel. |
