From mboxrd@z Thu Jan 1 00:00:00 1970 From: Zev Weiss Date: Fri, 2 Apr 2021 13:27:24 -0500 Subject: [PATCH v4 4/4] dt-bindings: serial: 8250: add aspeed, lpc-io-reg and aspeed, lpc-interrupts In-Reply-To: <20210402182724.20848-1-zev@bewilderbeest.net> References: <20210402182724.20848-1-zev@bewilderbeest.net> Message-ID: <20210402182724.20848-5-zev@bewilderbeest.net> List-Id: To: linux-aspeed@lists.ozlabs.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit These correspond to the existing lpc_address, sirq, and sirq_polarity sysfs attributes; the second element of aspeed,lpc-interrupts provides a replacement for the deprecated aspeed,sirq-polarity-sense property.
