Subject: [PATCH v1 0/2] pinctrl: intel: Fix PWM initialisation
Date: Mon, 10 Feb 2025 21:44:49 +0200	[thread overview]
Message-ID: <20250210195230.490904-1-andriy.shevchenko@linux.intel.com> (raw)

It appears that PWM instantiated from pinctrl-intel is configured
to a wrong flow. This mini-series to fix the issue. Note, patch 1
is comprehensive documentation paragraph to explain what the difference
in the programming flow and what the SoCs are affected.

The issue had been reported privately, hence no Closes tag.
I haven't added the Tested-by, so to make sure that it (still) works
I ask Alexis to give the formal Tag here in a response to the series.

The idea is to route this via pin control tree as there are already two patches
against PWM handling in pinctrl-intel. There is no need to backport that, it's
optional, because it wasn't worked from day 1, and hence no Cc: stable@.
