Subject: [PATCH v2 2/3] clk: rockchip: rk3399: expose PCLK_COREDBG_{B,L}
Date: Wed,  8 Sep 2021 11:13:39 -0700	[thread overview]
Message-ID: <20210908111337.v2.2.If29cd838efbcee4450a62b8d84a99b23c86e0a3f@changeid> (raw)
In-Reply-To: <20210908111337.v2.1.I006bb36063555079b1a88f01d20e38d7e4705ae0@changeid>

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.

Reviewed-by: Chen-Yu Tsai <wenst@chromium.org>
Signed-off-by: Brian Norris <briannorris@chromium.org>
---

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