Subject: [PATCH 14/17] i3c: mipi-i3c-hci: Remove invalid HDR-BT and Fm/Fm+ definitions
Date: Mon, 14 Sep 2026 14:30:00 +0300 [thread overview]
Message-ID: <20260914113003.183150-15-adrian.hunter@intel.com> (raw)
In-Reply-To: <20260914113003.183150-1-adrian.hunter@intel.com>
Several HCI definitions describe capabilities or modes that are not
defined by any released version of the I3C HCI specification.
HC_CAP_HDR_BT_EN uses a reserved HC_CAPABILITIES bit. Similarly,
MODE_I3C_HDR_BT uses a MODE value reserved for I3C transfers, while
MODE_I3C_Fm_FmP cannot be encoded in the 3-bit Command Descriptor MODE
field.
These definitions are currently unused, so there is no functional
change. Remove them to avoid implying support for non-existent HCI
features and to prevent future misuse.
