-/* AMD hw uses four ACPI control methods:
- * 1. ATIF
- * ARG0: (ACPI_INTEGER) function code
- * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
- * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
- * ATIF provides an entry point for the gfx driver to interact with the sbios.
- * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom
- * notification. Which notification is used as indicated by the ATIF Control
- * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or
- * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS
- * to identify pending System BIOS requests and associated parameters. For
- * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver
- * will perform display device detection and invoke ATIF Control Method
- * SELECT_ACTIVE_DISPLAYS.
- *
- * 2. ATPX
- * ARG0: (ACPI_INTEGER) function code
- * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
- * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
- * ATPX methods are used on PowerXpress systems to handle mux switching and
- * discrete GPU power control.
- *
- * 3. ATRM
- * ARG0: (ACPI_INTEGER) offset of vbios rom data
- * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K).
- * OUTPUT: (ACPI_BUFFER) output buffer
- * ATRM provides an interfacess to access the discrete GPU vbios image on
- * PowerXpress systems with multiple GPUs.
- *
- * 4. ATCS
- * ARG0: (ACPI_INTEGER) function code
- * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
- * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
- * ATCS provides an interface to AMD chipset specific functionality.

+/* AMD hw uses four ACPI control methods:
+ * 1. ATIF
+ * ARG0: (ACPI_INTEGER) function code
+ * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
+ * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
+ * ATIF provides an entry point for the gfx driver to interact with the sbios.
+ * The AMD ACPI notification mechanism uses Notify (VGA, 0x81) or a custom
+ * notification. Which notification is used as indicated by the ATIF Control
+ * Method GET_SYSTEM_PARAMETERS. When the driver receives Notify (VGA, 0x81) or
+ * a custom notification it invokes ATIF Control Method GET_SYSTEM_BIOS_REQUESTS
+ * to identify pending System BIOS requests and associated parameters. For
+ * example, if one of the pending requests is DISPLAY_SWITCH_REQUEST, the driver
+ * will perform display device detection and invoke ATIF Control Method
+ * SELECT_ACTIVE_DISPLAYS.
+ *
+ * 2. ATPX
+ * ARG0: (ACPI_INTEGER) function code
+ * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
+ * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
+ * ATPX methods are used on PowerXpress systems to handle mux switching and
+ * discrete GPU power control.
+ *
+ * 3. ATRM
+ * ARG0: (ACPI_INTEGER) offset of vbios rom data
+ * ARG1: (ACPI_BUFFER) size of the buffer to fill (up to 4K).
+ * OUTPUT: (ACPI_BUFFER) output buffer
+ * ATRM provides an interfacess to access the discrete GPU vbios image on
+ * PowerXpress systems with multiple GPUs.
+ *
+ * 4. ATCS
+ * ARG0: (ACPI_INTEGER) function code
+ * ARG1: (ACPI_BUFFER) parameter buffer, 256 bytes
+ * OUTPUT: (ACPI_BUFFER) output buffer, 256 bytes
+ * ATCS provides an interface to AMD chipset specific functionality.
