Yes. As far as I understand, the previous Exynos variants used one TMU controller per sensor,
while on ExynosAutoV920 the hardware has multiple TMU instances and each instance contains multiple sensors.
Therefore, this new automotive SoC requires supporting multiple sensors behind a single TMU controller.
