[RFC v2 0/5] arm64 / clk: socfpga: simplifying, cleanups and compile testing

From: Krzysztof Kozlowski
Date: Wed Mar 10 2021 - 03:34:36 EST


Hi,

All three Intel arm64 SoCFPGA architectures (Agilex, N5X and Stratix 10)
are basically flavors/platforms of the same architecture. At least from
the Linux point of view. Up to a point that N5X and Agilex share DTSI.
Having three top-level architectures for the same one barely makes
sense and complicates driver selection.

Try to unify them.

Changes since v1:
=================
1. New patch 3/5: arm64: socfpga: rename ARCH_STRATIX10 to ARCH_SOCFPGA64
2. New patch 4/5: arm64: intel: merge Agilex and N5X into ARCH_SOCFPGA64
3. Fix build issue reported by kernel test robot (with ARCH_STRATIX10
and COMPILE_TEST but without selecting some of the clocks).

I tested compile builds on few configurations, so I hope kbuild 0-day
will check more options (please give it few days on the lists).

Best regards,
Krzysztof
