From: Oded Gabbay <ogabbay@...nel.org>
To: linux-kernel@...r.kernel.org
Subject: [PATCH 13/30] habanalabs: add vrm version to sysfs
infineon version is only applicable to GOYA and GAUDI. For later
ASICs, we display the Voltage Regulator Monitor f/w version.
Signed-off-by: Oded Gabbay <ogabbay@...nel.org>
