From mboxrd@z Thu Jan 1 00:00:00 1970 From: alexandre.belloni@bootlin.com (Alexandre Belloni) Date: Mon, 3 Sep 2018 16:08:38 +0200 Subject: [PATCH v2 3/5] arm64: dts: fsl: ls1046a: disable uarts by default In-Reply-To: <20180903140840.23648-1-alexandre.belloni@bootlin.com> References: <20180903140840.23648-1-alexandre.belloni@bootlin.com> Message-ID: <20180903140840.23648-3-alexandre.belloni@bootlin.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Disable the UARTs by defaultto avoid registering unused UARTs. This effectively change the number of registered UARTS for the RDB and QDS from 4 to 2 but this seems the right thing to do. It is especially useful when connecting other 8250 uart on PCIe for example as the default maximum number of 8250 UARTs that can be registered is 4.
