[PATCH 2/8] drm/panthor: Split register definitions by components

Karunika Choo
2026-04-10T16:47:55Z

Split the panthor register definitions into per-component headers for
the GPU, MMU, firmware, power and generic hardware registers.

This makes the register layout easier to follow and prepares the driver
for component-local iomem mappings by grouping definitions with the code
that owns them. The old monolithic panthor_regs.h header can then be
dropped.

No functional change intended.
