[PATCH v2 2/3] clk: rockchip: rk3399: expose PCLK_COREDBG_{B,L}

From: Brian Norris
Date: Wed Sep 08 2021 - 14:14:06 EST


We have DT IDs for PCLK_COREDBG_L and PCLK_COREDBG_B, but we don't
actually expose them.

Note that this requires the previous patch (making "armclkl" and
"armclkb" into "critical" clocks) to prevent these clocks from taking
down the CPU.

Changes in v2:
- Split "CPU clocks are critical" to a new patch, to make it more
obvious
