explicit handling of common clock would require since the A64 doesn't need to mention the clock-names explicitly in dts since it support only one bus clock.
Also pass clk_id NULL instead "bus" to regmap clock init function since the single clock variants no need to mention clock-names explicitly.
You don't need explicit clock handling. Passing NULL as the argument in regmap_init_mmio_clk will make it use the first clock, which is the bus clock.
Indeed I tried that, since NULL clk_id wouldn't enable the bus clock during regmap_mmio_gen_context code, passing NULL triggering vblank timeout.
There's a bunch of users of NULL in tree, so finding out why NULL doesn't work is the way forward.
