Subject: [PATCH v3 00/15] arm64 / clk: socfpga: simplifying, cleanups and compile testing
Date: Thu, 11 Mar 2021 16:25:30 +0100 [thread overview]
Message-ID: <20210311152545.1317581-1-krzysztof.kozlowski@canonical.com> (raw)
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.
Additionally it was pointed out that ARCH_SOCFPGA name is too generic.
There are other vendors making SoC+FPGA designs, so the name should be
changed to have real vendor (currently: Intel).
Dependencies / merging
======================
1. Patch 1 is used as base, so other changes depend on its hunks.
I put it at beginning as it is something close to a fix, so candidate
for stable (even though I did not mark it like that).
2. Patch 2: everything depends on it.
3. 64-bit path:
3a. Patches 3-7: depend on patch 2, from 64-bit point of view.
3b. Patch 8: depends on 2-7 as it finally removes 64-bit ARCH_XXX
symbols.
4. 32-bit path:
4a. Patches 9-14: depend on 2, from 32-bit point of view.
4b. Patch 15: depends on 9-14 as it finally removes 32-bit ARCH_SOCFPGA
symbol.
If the patches look good, proposed merging is via SoC tree (after
getting acks from everyone). Sharing immutable branches is also a way.
Changes since v2
================
1. Several new patches and changes.
2. Rename ARCH_SOCFPGA to ARCH_INTEL_SOCFPGA on 32-bit and 64-bit.
3. Enable compile testing of 32-bit socfpga clock drivers.
4. Split changes per subsystems for easier review.
5. I already received an ack from Lee Jones, but I did not add it as
there was big refactoring. Please kindly ack one more time if it
looks good.
Changes since v1
================
1. New patch 3: arm64: socfpga: rename ARCH_STRATIX10 to ARCH_SOCFPGA64.
2. New patch 4: arm64: intel: merge Agilex and N5X into ARCH_SOCFPGA64.
3. Fix build is.sue reported by kernel test robot (with ARCH_STRATIX10
and COMPILE_TEST but without selecting some of the clocks).
RFT
===
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).
I compare the generated autoconf.h and found no issues. Testing on real
hardware would be appreciated.
Best regards,
Krzysztof
