The cover letter to that patchset also mentions adding an unused "reg"<br class="gmail_msg">
property as a workaround. I had probably copied and pasted the pca9541<br class="gmail_msg">
bindings without "reg" to the Zaius dts without reading the rest of<br class="gmail_msg">
the notes. Oops.<br class="gmail_msg">
<br class="gmail_msg">
Should we backport that patchset and/or wait for the next OpenBMC kernel rebase?<br class="gmail_msg">
<br class="gmail_msg">
Emily: can you test whether the "reg" property is still necessary if<br class="gmail_msg">
you backport those patches?<br class="gmail_msg">
