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

2016-03-02T00:55:48+00:00

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

2015-08-05T20:44:24+00:00

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.

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

2013-09-26T20:47:36+00:00

Allwinner has electric fuses (efuse) on their line of chips. This driver reads those fuses, seeds the kernel entropy and exports them as a sysfs node. These fuses are most likely to be programmed at the factory, encoding things like Chip ID, some sort of serial number, etc. and appear to be reasonably unique. While in theory, these should be writeable by the user, it will probably be 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 an UEFI 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

drivers: misc: at24: mention other supported types in Kconfig

2013-01-28T04:26:41+00:00

As the at24 driver is able handle a bunch of serial storage chips other than EEPROMs this is now mentioned in Kconfig. Signed-off-by: Lars Poeschel Signed-off-by: Wolfram Sang

char/misc: remove CONFIG_EXPERIMENTAL dependencies

2012-09-18T15:14:53+00:00

As discussed at the kernel summit this year, CONFIG_EXPERIMENTAL means nothing, so let's get rid of it. Cc: Kees Cook Cc: Arnd Bergmann Cc: Tomas Winkler Cc: Jiri Kosina Cc: Paul Bolle Cc: Andrew Morton Cc: Anatolij Gustschin Signed-off-by: Greg Kroah-Hartman

drivers/misc/eeprom: fix dependecy on 'PPC_MPC5200_GPIO'

2011-11-16T00:41:51+00:00

The driver for the DigsyMTC display configuration EEPROMs device got added by commit 469dded183 ("misc/eeprom: add eeprom access driver for digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But at the time that driver got added PPC_MPC5200_GPIO was already renamed to GPIO_MPC5200, by commit 6eae1ace68 ("gpio: Move mpc5200 gpio driver to drivers/gpio"). So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200 itself implies that GPIOLIB is set, that dependency can be dropped.

misc/eeprom: add eeprom access driver for digsy_mtc board

2011-07-26T03:57:16+00:00

Both displays on digsy_mtc board obtain their configuration from microwire EEPROMs which are connected to the SoC over GPIO lines. We need an easy way to access the EEPROMs to write the needed display configuration or to read out the currently programmed configuration. The generic eeprom_93xx46 SPI driver added by previous patch allows EEPROM access over sysfs. Using the simple driver added by this patch we provide used GPIO interface and access control description on the board for generic eeprom_93xx46 driver and spi_gpio driver.

misc/eeprom: add driver for microwire 93xx46 EEPROMs

2011-07-26T03:57:16+00:00

Add EEPROM driver for 93xx46 chips. It can also be used with spi_gpio driver to access 93xx46 EEPROMs connected over GPIO lines. This driver supports read/write/erase access to the EEPROM chips over sysfs files.
