Subject: [PATCH 0/2] Update handling of min and max channel in DisCo
Date: Mon,  9 Nov 2026 17:38:41 +0000	[thread overview]
Message-ID: <20261109173843.4184154-1-ckeepax@opensource.cirrus.com> (raw)

The DisCo properties "mipi-sdw-min-channel-number" and
"mipi-sdw-max-channel-number" are both channel indexes rather than
counts. Update the kernel code to more accurately reflect this.

There are a few Qualcomm drivers that likely specify these incorrect,
min_ch=1, max_ch=X, rather than min_ch=0, max_ch=X-1, however these
should work fine as the number of supported channels is equivalent.
If people feel strongly I can send another series to fix those up.

  soundwire: Assume default maximum valid channel if not specified
