[PATCH 1/3] ARM: imx25: support silicon revision 1.2

[Martin Kaiser]

Update the mx25_read_cpu_rev function to recognize silicon revision 1.2
for imx25 chipsets.

Silicon revision 1.2 is mentioned in the errata document at
https://www.nxp.com/docs/en/errata/IMX25CE.pdf. The imx25 chips on my
test boards show revision 1.2 as well.

[PATCH v3 1/2] clk: imx25: print silicon revision during init

[Martin Kaiser]

Print the imx25 silicon revision when the clocks are initialised.

Use the same mechanism as for imx27, i.e. call mx25_revision.
This function is unused at the moment.

[PATCH v3 2/2] clk: imx25: make __mx25_clocks_init return void

[Martin Kaiser]

The __mx25_clocks_init function always returns 0 and its only
caller does not check the return value. Let's remove it.

[PATCH v4 0/2] ARM: imx25: print silicon revision at startup

[Martin Kaiser]

Resurrect the unused function to print the imx25 silicon revision at
startup.

Now that 6.0-rc1 is out, I hope that the clk maintainers have a moment
to review this simple patch set ;-)

changes in v4:
- rebase against today's linux-next
- add Fabio's Reviewed-by tags

changes in v3:
- rebase against today's linux-next

changes in v2:
- drop the patch about silicon revision 1.2. It has already been merged
  by Shawn Guo.
- send the changeset to the clk maintainers

[PATCH v5 2/2] clk: imx25: make __mx25_clocks_init return void

[Martin Kaiser]

The __mx25_clocks_init function always returns 0 and its only
caller does not check the return value. Let's remove it.

Looks good to me, and fixes the warning about the function having

[PATCH v6 0/2] ARM: imx25: print silicon revision at startup

[Martin Kaiser]

Resurrect the unused function to print the imx25 silicon revision at
startup.

This patch set is blocking Arnd's work on enabling -Werror=missing-prototypes.

I'd really appreciate a response from the clk maintainers if these (trivial)
patches are ok.

Thanks,
Martin

[Martin Kaiser]

Print the imx25 silicon revision when the clocks are initialised.

Use the same mechanism as for imx27, i.e. call mx25_revision.
This function is unused at the moment.

You need to Cc linux-imx@nxp.com on imx clk patches. I think Abel has
some filter that looks for linux-clk@vger and linux-imx.

Also, please don't send series replies to previous rounds. It buries the
patches deep in my MUA and my scripts don't work well to apply patches
when they're sent like that.

I presume that Abel will pick the patches up? Or do you want to land
them through Arnd's tree? Either way feel free to add my acked-by

Thanks for responding, Stephen.

Ok, understood. I'll resend with Cc linux-imx@nxp.com and without the
reply to previous versions.

Arnd, are you ok with taking these patches through your tree as
suggested by Stephen?

I prefer to have Abel apply the patches through clk tree rather than
arm-soc tree, unless there is a good reason for them to go via the
latter.

ok with me. I'd be happy to get this sorted (one way or another) so that
Arnd can enable -Werror=missing-prototypes for 6.6.
