There's no need to add a new one in the driver (for now). And you still haven't fixed the size. Maxime

A64 PWM controller has same register layout as sun4i driver, so it works by adding A64 specific data. Signed-off-by: Icenowy Zheng <icenowy@aosc.xyz> --- drivers/pwm/pwm-sun4i.c | 9 +++++++++ 1 file changed, 9 insertions(+)
