+Subject: [PATCH] platform/x86: asus-wmi: disable USB0 hub on ROG Ally before
+ suspend
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+ASUS have worked around an issue in XInput where it doesn't support USB
+selective suspend, which causes suspend issues in Windows. They worked
+around this by adjusting the MCU firmware to disable the USB0 hub when
+the screen is switched off during the Microsoft DSM suspend path in ACPI.
+
+The issue we have with this however is one of timing - the call the tells
+the MCU to this isn't able to complete before suspend is done so we call
+this in a prepare() and add a small msleep() to ensure it is done. This
+must be done before the screen is switched off to prevent a variety of
+possible races.
+
+Further to this the MCU powersave option must also be disabled as it can
+cause a number of issues such as:
+- unreliable resume connection of N-Key
+- complete loss of N-Key if the power is plugged in while suspended
+Disabling the powersave option prevents this.
+
+Without this the MCU is unable to initialise itself correctly on resume.
