From 2606acfd4b6f31ea55f702736c34e7a823ba4bfa Mon Sep 17 00:00:00 2001 From: Jonathon Hall Date: Wed, 12 Apr 2023 14:32:01 -0400 Subject: mb/purism/librem_cnl: Configure SuperIO for Librem Mini v1/v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Configure the SuperIO and logical devices in the device tree. This overrides the power-on default state. UART1 was already enabled, and if ENABLE_EC_UART1 was selected in Kconfig, the LPC UART1 I/O range was also already enabled. The RTC/BRAM interface was enabled (and the BRAM1 base was 0x360 by default), but the LPC I/O range was not opened previously. Now it is open and BRAM bank 1 is accessible. Mouse/Keyboard are not wired to anything on this board and are now disabled. UART2, SMFI, power channel 1, and power channel 2 were enabled previously, but their LPC I/O ranges were not opened and they were not accessible to the OS. Fan control is performed by the EC on this board so there is no change. SWUC and power channels 3-5 were disabled by default, no change.
