2013-09-27ARM: sunxi: Initial support for Allwinner's Security ID fusesOliver Schinagl3-0/+172
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 <oliver@schinagl.nl> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-09-06misc/at25, dt: Improve at25 SPI eeprom device tree bindings.David Daney1-25/+58
Commit 002176db (misc: at25: Parse dt settings) added device tree bindings the differ significantly in style from the I2C EEPROM bindings and don't seem well vetted. Here I deprecate (but still support) the "at25,*" properties, and add what I hope is a better alternative. These new bindings also happen to be deployed in the field and were previously submitted for consideration here: https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-May/015556.html The advantages of the new bindings are that they are similar to the I2C EEPROMs and they don't conflate read-only and the address width modes in a binary encoded blob.

Updated the generic SPI EEPROM driver AT25 for support of an additional address bit in the instruction byte. Certain EEPROMS have a size that is larger than the number of address bytes would allow (e.g. like M95040 from ST that has 512 Byte size but uses only one address byte (A0 to A7) for addressing.) For the extra address bit (A8, A16 or A24) bit 3 of the instruction byte is used. This instruction bit is normally defined as don't care for other AT25 like chips.

2011-11-16drivers/misc/eeprom: fix dependecy on 'PPC_MPC5200_GPIO'Paul Bolle1-1/+1
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.

Both displays on digsy_mtc board obtain their configuration from microwire EEPROMs which are connected to the SoC over GPIO lines.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang1-1/+0
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-05-21at24: Fall back to byte or word reads if neededJean Delvare1-11/+48
Increase the portability of the at24 driver by letting it read from EEPROM chips connected to cheap SMBus controllers that support neither raw I2C messages nor even I2C block reads. All SMBus controllers should support either word reads or byte reads, so read support becomes universal, much like with the legacy "eeprom" driver. Obviously, this only works with EEPROM chips up to AT24C16, that use 8-bit offset addressing. 16-bit offset addressing is almost impossible to support on SMBus controllers. I did not add universal support for writes, as I had no immediate need for this, but it could be added later if needed (with the same performance issue as byte and word reads have, of course.)

There is no point in implementing a detect callback for the MAX6875, as this device can't be detected. It was there solely to handle "force" module parameters to instantiate devices, but now we have a better sysfs interface that can do the same. So we can get rid of the ugly module parameters and the detect callback. This basically divides the binary module size by 2.

2009-09-23spi: prefix modalias with "spi:"Anton Vorontsov1-1/+1
This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

2009-07-30eeprom/at25: bugfix "not ready" timeout after writeSebastian Heutling1-2/+2
Under certain circumstances msleep(1) within the loop, which waits for the EEPROM to be finished, might take longer than the timeout. On the next loop the status register might now return to be ready and therefore the loop finishes. The following check now tests if a timeout occurred and if so returns an error although the device reported it was ready. This fix replaces testing the occurrence of the timeout by testing the "not ready" bit in the status register.

2009-06-15i2c/chips: Move max6875 to drivers/misc/eepromWolfram Sang3-0/+261
This driver only reads the user EEPROM of that chip, so we can move it to the eeprom-directory in order to further clean up (and later remove) drivers/i2c/chips. The Kconfig text was updated to match the current functionality, dropping the meanwhile obsoleted parts. Defconfigs have been adapted.
