Part 5 - 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...

Since the BSP version is different, and we understand that there are several differences on regards of BSP33.0 and BSP38.0, the initialization of BSP38.0 might look into disabling (or not enabling) unused peripherals/clocks. If you enable LLCE under BSP38.0, are you seeing any problems with ...
I have thus added a few debug printks to clk_*_unused_subtree to confirm the root cause (this is with CLK_IGNORE_UNUSED): [ 2.846401] clk: enable count for gcc_aggre1_ufs_axi_hw_ctl_clk is 0 [ 2.846487] clk: not disabling unused gcc_aggre1_ufs_axi_hw_ctl_clk [ 2.846533] clk...
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 ...
