I thought I had addressed all the issues with the v9 version. The only comments
I got on it was Mike's reviewed-by and I didn't think that warranted a resend.
If you do want me to send it again, do you want it updated to current
top-of-tree? That may take a bit, since there's an unrelated bug

This lets of_gpio_named_count return an errno on errors by being able to

and only this errno will indicate to a spi controller driver that a
Return value for an empty phandle was -EEXIST before commit 15c9a0ac, that
changed the return value in this case to -ENOENT. However, of_gpio_named_count
relies upon the return value to be -EEXIST and relies upon being able to
distinguish this case from the case of no list at all which also

Hi Sergei,
Yes, you are right.
I made this patch to read its interrupt number from dtb directly. But
now platform_get_irq() returns correct irq since "OF_DEV_AUXDATA(...)"
is added as my first patch.
This patch is useless.
Thanks and best regards,

The "pid" sort key prints "Command: Pid" output but it's misaligned.
It's because of the offset of 6 was added to the column length during
the calculation in order to reserve an space for Pid part but it isn't
honored when printed. The output before this patch was like this:

When hists__calc_col_len() called, most of column length are refreshed

Since Efika MX platform support (pre-devicetree) was removed from the tree
this code no longer has any possibility of running and clutters up the
driver which is being replaced by the chipidea host in the future anyway.

Hi Sergei,
Yes, you are right.
I made this patch to read its interrupt number from dtb directly. But
now platform_get_irq() returns correct irq since OF_DEV_AUXDATA(...)
is added as my first patch.
This patch is useless.
Thanks and best regards,
Dongjin.

This patch series fixes a bug where of_gpio_named count relied upon a return
value that was no longer returned from of_parse_phandle_with_args and adds the
possibility for of_gpio_named_count to return error values.
In addition, for of_spi_register_master it fixes a bug, adds documentation,

Holes in the cs-gpios DT phandle list is supposed to mark that native
chipselects is to be used. The value returned from of_get_named_gpio_flags in
this case is -EEXIST. By initializing cs_gpios and cs_gpio with -EEXIST, this
and only this errno will indicate to a spi controller driver that a
Return value for an empty phandle was -EEXIST before commit 15c9a0ac, that
changed the return value in this case to -ENOENT. However, of_gpio_named_count
relies upon the return value to be -EEXIST and relies upon being able to
distinguish this case from the case of no list at all which also
