+Subject: [PATCH 37/38] ec/dell/mec5035: Replace defines with enums
+
+Instead of using defines for command IDs and argument values, use enums
+to provide more type safety. This also has the effect of moving the
+command IDs to a more central location instead of defines spread out
+throughout the header.

-Subject: [PATCH 37/65] ec/dell/mec5035: Add S3 suspend SMI handler
+Subject: [PATCH 38/38] ec/dell/mec5035: Add S3 suspend SMI handler
+
+This is necessary for S3 resume to work on SNB and newer Dell Latitude
+laptops. If a command isn't sent, the EC cuts power to the DIMMs,
+preventing the system from resuming. These commands were found using an
+FPGA to log all LPC bus transactions between the host and the EC and
+then narrowing down which ones were actually necessary.
+
+Interestingly, the command IDs appear to be identical to those in
+ec/google/wilco, the EC used on Dell Latitude Chromebooks, and that EC
+implements a similar S3 SMI handler as the one implemented in this
+commit. The Wilco EC Kconfig does suggest that its firmware is a
+modified version of Dell's usual Latitude EC firmware, so the
+similarities seem to be intentional.
+
+These similarities also identified a command to enable or disable wake
+sources like the power button and lid switch, and this was added to the
+SMI handler to disable lid wake as the system does not yet resume
+properly from a like wake with coreboot.
+
+Tested on the Latitude E6430 (Ivy Bridge) and the Precision M6800
+(Haswell, not yet pushed).

+The E6400 does not require the EC command to sucessfully suspend and

+Subject: [PATCH 67/67] ec/dell/mec5035: Route power button event to host
+
+If command 0x3e with an argument of 1 isn't sent to the EC, pressing the
+power button results in the EC powering off the system without letting
+the OS cleanly shutting itself down. This command and argument tells the
+EC to route power button events to the host so that it can determine
+what to do.
+
+The EC command was identified from the ec/google/wilco code, which is
+used for Dell's Latitude Chromebooks. According to the EC_GOOGLE_WILCO
+Kconfig help text, those ECs run a modified version of Dell's typical
+Latitude EC firmware, so it is likely that the two firmware
+implementations use similar commands. Examining LPC traffic between the
+host and the EC on the Latitude E6400 did reveal that the same command
+was being sent by the vendor firmware to the EC, but this does not
+confirm that it has the same meaning as the command from the Wilco code.
+Sending the command using inb/outb calls in a userspace C program while
+running coreboot without this patch did allow subsequent power button
+events to be handled by the host, confirming that the command was indeed
+the same.
