From: Andrew Jeffery Date: Wed, 23 Jun 2021 03:38:51 +0000 (+0930) Subject: ARM: dts: aspeed: p10bmc: Use KCS 3 for MCTP binding X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d4efb68f170587cf0decc97f522dee56cfae8cea;p=linux.git ARM: dts: aspeed: p10bmc: Use KCS 3 for MCTP binding The MCTP LPC driver was loaded by hacking up the compatible in the devicetree node for KCS 4. With the introduction of the raw KCS driver this hack is no-longer required. Use the regular compatible string for KCS 4 and configure the appropriate SerIRQ. The reset state of the status bits on KCS 4 is inappropriate for the MCTP LPC binding. Switch to KCS 3 which has a different reset behaviour.
