Subject: [PATCH v3 4/4] dt-bindings: serial: 8250: add aspeed, lpc-address and aspeed, sirq
Date: Thu, 1 Apr 2021 19:47:16 -0500 [thread overview]
Message-ID: <20210402004716.15961-5-zev@bewilderbeest.net> (raw)
In-Reply-To: <20210402004716.15961-1-zev@bewilderbeest.net>
These correspond to the existing lpc_address, sirq, and sirq_polarity
sysfs attributes; the second element of aspeed,sirq provides a
replacement for the deprecated aspeed,sirq-polarity-sense property.
