Subject: [PATCH] clk: rockchip: rk3588: fix CLK_NR_CLKS usage
|
|
|
|
CLK_NR_CLKS is not part of the DT bindings and needs to be removed
|
|
from it, just like it recently happened for other platforms. This
|
|
takes care of it by introducing a new function identifying the
|
|
maximum used clock ID at runtime.
