Subject: [PATCH 0/2] spi: ma35d1-qspi: Flag the DTR capability correctly
Date: Fri, 04 Sep 2026 18:15:09 +0200 [thread overview]
Message-ID: <20260904-perso-ma35d1-master-v1-0-b6936e8c6fa1@bootlin.com> (raw)
Mark pointed out that the DTR capability was not correctly enabled since
I had to set the extra ctlr->dtr_caps flag. For testing, I commented out
the spi-mem ops/caps and figured out DTR variants were still not picked
up. This was due to the spi-mem fallback implementation of ->exec_op()
not forwarding the DTR flag.
