What:           /sys/class/accel/accel<n>/device/armcp_kernel_ver
Date:           Jan 2019
KernelVersion:  5.1
Contact:        ogabbay@kernel.org
Description:    Version of the Linux kernel running on the device's CPU.
                Will be DEPRECATED in Linux kernel version 5.10, and be
                replaced with cpucp_kernel_ver

What:           /sys/class/accel/accel<n>/device/armcp_ver
Date:           Jan 2019
KernelVersion:  5.1
Contact:        ogabbay@kernel.org
Description:    Version of the application running on the device's CPU
                Will be DEPRECATED in Linux kernel version 5.10, and be
                replaced with cpucp_ver

What:           /sys/class/accel/accel<n>/device/clk_max_freq_mhz
Date:           Jun 2019
KernelVersion:  5.7
Contact:        ogabbay@kernel.org
Description:    Allows the user to set the maximum clock frequency, in MHz.
                The device clock might be set to lower value than the maximum.
                The user should read the clk_cur_freq_mhz to see the actual
                frequency value of the device clock. This property is valid
                only for the Gaudi ASIC family

What:           /sys/class/accel/accel<n>/device/clk_cur_freq_mhz
Date:           Jun 2019
KernelVersion:  5.7
Contact:        ogabbay@kernel.org
Description:    Displays the current frequency, in MHz, of the device clock.
                This property is valid only for the Gaudi ASIC family

Contact:        ogabbay@kernel.org
Description:    Displays the code name of the device according to its type.
                The supported values are: "GOYA"

What:           /sys/class/accel/accel<n>/device/eeprom
Date:           Jan 2019
KernelVersion:  5.1
Contact:        ogabbay@kernel.org
Description:    A binary file attribute that contains the contents of the
                on-board EEPROM
