Ok, so your Clapper model indeed is also using clk 0 and not clk 3 as
expected. I've just submitted a patch upstream adding a quirk for this.
As for what the plan is with 4.14, I don't know. I believe that
reverting the commit causing the issue there is fine.

Hello,
We ran automated tests on a recent commit from this kernel tree:
Kernel repo: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
Commit: 96db90800c06 Linux 4.19.6
The results of these automated tests are provided below.
Overall result: PASSED
Patch merge: OK
Compile: OK
Kernel tests: OK
Please reply to this email if you have any questions about the tests that we
ran or if you have any suggestions on how to make future tests more effective.

Compile testing
---------------
We compiled the kernel for 2 architectures:
x86_64:
make options: make INSTALL_MOD_STRIP=1 -j56 targz-pkg
configuration: https://artifacts.cki-project.org/builds/x86_64/96db90800c06d3fe3fa08eb6222…
aarch64:
make options: make INSTALL_MOD_STRIP=1 -j56 targz-pkg
configuration: https://artifacts.cki-project.org/builds/aarch64/96db90800c06d3fe3fa08eb622…
Hardware testing
----------------
We booted each kernel and ran the following tests:
x86_64:
/distribution/kpkginstall (boot test)
LTP lite - release 20180515
xfstests: ext4
xfstests: xfs
/kernel/misc/amtu
arm64:
/distribution/kpkginstall (boot test)
LTP lite - release 20180515
xfstests: ext4
xfstests: xfs
/kernel/misc/amtu
