| 2019-05-14 | scripts/gdb: print cached rate in lx-clk-summary | Leonard Crestez | 1 | -7/+14 | |
| The clk rate is always stored in clk_core but might be out of date and require calls to update from hardware. Deal with that case by printing a (c) suffix.

| 2019-05-14 | scripts/gdb: add $lx_clk_core_lookup function | Leonard Crestez | 1 | -0/+23 | |
| Finding an individual clk_core requires walking the tree which can be quite complicated so add a helper for easy access.

| 2019-05-14 | scripts/gdb: initial clk support: lx-clk-summary | Leonard Crestez | 1 | -0/+46 | |
| Add an lx-clk-summary command which prints a subset of /sys/kernel/debug/clk/clk_summary. This can be used to examine hangs caused by clk not being enabled.
