eeprom: New ee1004 driver for DDR4 memory

2018-10-15T18:51:46Z

The EEPROMs which hold the SPD data on DDR4 memory modules are no longer standard AT24C02-compatible EEPROMs. They are 512-byte EEPROMs which use only 1 I2C address for data access. You need to switch between the lower page and the upper page of data by sending commands on the SMBus. Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

eeprom: at24: add basic regmap_i2c support

eeprom: Add IDT 89HPESx EEPROM/CSR driver

2017-01-19T10:39:57Z

This driver provides an access to EEPROM of IDT PCIe-switches. IDT PCIe- switches expose a simple SMBus interface to perform IO-operations from/to EEPROM, which is located at private (so called Master) SMBus. The driver creates a simple binary sysfs-file to have an access to the EEPROM using the SMBus-slave interface in the i2c-device susfs-directory: /sys/bus/i2c/devices/-/eeprom In case if read-only flag is specified at dts-node of the device, User-space applications won't be able to write to the EEPROM sysfs-node. Additionally IDT 89HPESx SMBus interface has an ability to read/write values of device CSRs. This driver exposes debugfs-file to perform simple IO-operations using that ability for just basic debug purpose. Particularly the 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 just write 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 write operation is: $ echo ":" > \ /sys/kernel/debug/idt_csr/-/; CSR address and value can be any of hexadecimal, decimal or octal format.

eeprom: at25: remove nvmem regmap dependency

This patch moves to nvmem support in the driver to use callback instead of regmap. Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

eeprom: 93xx46: extend driver to plug into the NVMEM framework

2016-03-02T00:55:48Z

Add a regmap for accessing the EEPROM, and then use that with the NVMEM framework. Enable backward compatibility in the NVMEM config structure, so that the 'eeprom' file in sys is provided by the framework. Signed-off-by: Andrew Lunn Acked-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: sunxi: Move the SID driver to the nvmem framework

2015-08-05T20:44:24Z

Now that we have the nvmem framework, we can consolidate the common driver code. Move the driver to the framework, and hopefully, it will fix the sysfs file creation race.
