Tue, 25 Jun 2024 06:34:59 +0000

eeprom: ee1004: Add nvmem supportCurrently the driver does not register a nvmem provider, which meansthat userspace programs cannot access the ee1004 EEPROM through thestandard nvmem sysfs API.Fix this by replacing the custom sysfs attribute with a standard nvmeminterface, which also takes care of backwards compatibility.Tested on a Dell Inspiron 3505.Signed-off-by: Armin Wolf Link: https://lore.kernel.org/r/20240625063459.429953-2-W_Armin@gmx.deSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/eeprom/Kconfig

eeprom: make older eeprom drivers select NVMEM_SYSFSmisc/eeprom/{at24,at25,eeprom_93xx46} drivers all register theircorresponding devices in the nvmem framework in compat mode which requiresnvmem sysfs interface to be present. The latter, however, has been splitout from nvmem under a separate Kconfig in commit ae0c2d725512 ("nvmem:core: add NVMEM_SYSFS Kconfig"). As a result, probing certain I2C-attachedEEPROMs now fails with at24: probe of 0-0050 failed with error -38because of a stub implementation of nvmem_sysfs_setup_compat()in drivers/nvmem/nvmem.h.

cfad6425 - eeprom: Add IDT 89HPESx EEPROM/CSR driver

Fri, 13 Jan 2017 12:16:52 +0000

eeprom: Add IDT 89HPESx EEPROM/CSR driver This driver provides an access to EEPROM of IDT PCIe-switches. IDT PCIe-switches expose a simple SMBus interface to perform IO-operations from/toEEPROM, which is located at private (so called Master) SMBus. The drivercreates a simple binary sysfs-file to have an access to the EEPROM usingthe SMBus-slave interface in the i2c-device susfs-directory: /sys/bus/i2c/devices/-/eepromIn case if read-only flag is specified at dts-node of the device, User-spaceapplications won't be able to write to the EEPROM sysfs-node. Additionally IDT 89HPESx SMBus interface has an ability to read/writevalues of device CSRs. This driver exposes debugfs-file to perform simpleIO-operations using that ability for just basic debug purpose. Particularlythe next file is created in the specific debugfs-directory: /sys/kernel/debug/idt_csr/Format of the debugfs-file value is: $ cat /sys/kernel/debug/idt_csr/-/; :So reading the content of the file gives current CSR address and it value.If User-space application wishes to change current CSR address, it can justwrite a proper value to the sysfs-file: $ echo "" > /sys/kernel/debug/idt_csr/-/If it wants to change the CSR value as well, the format of the writeoperation is: $ echo ":" > \ /sys/kernel/debug/idt_csr/-/;CSR address and value can be any of hexadecimal, decimal or octal format.Signed-off-by: Serge Semin Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/eeprom/Kconfig

9fd379e9 - ARM: sunxi: Initial support for Allwinner's Security ID fuses

Tue, 03 Sep 2013 10:33:27 +0000

ARM: sunxi: Initial support for Allwinner's Security ID fusesAllwinner has electric fuses (efuse) on their line of chips. This driverreads those fuses, seeds the kernel entropy and exports them as a sysfsnode.These fuses are most likely to be programmed at the factory, encodingthings like Chip ID, some sort of serial number, etc. and appear to bereasonably unique.While in theory, these should be writeable by the user, it will probablybe inconvenient to do so. Allwinner recommends that a certain input pin,labeled 'efuse_vddq', be connected to GND. To write these fuses however,a 2.5 V programming voltage needs to be applied to this pin.Even so, they can still be used to generate a board-unique mac from,board unique RSA key and seed the kernel RNG.On sun7i additional storage is available, this is initially used for anUEFI BOOT key, Secure JTAG key, HDMI-HDCP key and vendor specific keys.Currently supported are the following known chips:Allwinner sun4i (A10)Allwinner sun5i (A10s, A13)Allwinner sun7i (A20)Signed-off-by: Oliver Schinagl Acked-by: Maxime Ripard Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/misc/eeprom/Kconfig
