[PATCH 0/4] pinctrl: sh-pfc: Run-time debug code fixes and enhancements

[Geert Uytterhoeven]

	Hi Linus,

This patch series contains several fixes and enhancements for the
debug code to validate pinctrl tables at run-time.

I intend to queue this in sh-pfc-for-v5.3.

Thanks for your comments!

Geert Uytterhoeven (4):
  pinctrl: sh-pfc: Correct printk level of group referral warning
  pinctrl: sh-pfc: Mark run-time debug code __init
  pinctrl: sh-pfc: Add check for empty pinmux groups/functions

[PATCH 2/4] pinctrl: sh-pfc: Mark run-time debug code __init

[PATCH 3/4] pinctrl: sh-pfc: Add check for empty pinmux groups/functions

[Geert Uytterhoeven]

The pinmux groups and functions arrays may contain two parts, to ease
supporting SoCs that expose pin subsets of other related SoCs.  Both
parts need to be declared with explicit sizes, which thus need to be
updated when adding support for more groups and functions.

If a size is too small, the compiler will detect this at build time
("excess elements in array initializer").
If a size is too large, this may go undetected (for pin groups), lead to
pin controller registration failures (for pin functions: "pinmux ops has
no name for functionN"), or crash the optional run-time debug code (for
pin groups).

Extend the run-time debug code with checks to detect this, to help
catching bugs early.

Not strictly related to this patch but did
you consider not having sh_pfc_errors global to this file?

Do you have an alternative?
I could hide it, and combine it with the pr_err() in a sh_pfc_report_error()
function, but it would still be global.

I didn't look carefully for an alternative.
If its not practical to pass around a local variable then
I'm happy with the current setup.

[PATCH 4/4] pinctrl: sh-pfc: Validate pin tables at runtime

[Geert Uytterhoeven]

Extend the run-time debug code with checks to ensure there are no
conflicting pin names, numbers, or enumeration values.

This helps catching bugs early.
