Allow the mma8452 to be described in the device tree.

Since no device specific binding attributes exist the trivial
I2C binding is sufficient to describe the compatible string.

Intersil ISL12057 is an I2C RTC chip also supporting two alarms. This
patch only adds support for basic RTC functionalities (i.e. getting
and setting time). Tests have been performed on NETGEAR ReadyNAS 102
w/ startup/shutdown scripts, hwclock, ntpdate and openntpd.

That driver was never merged, I have taken it as a starting port,
forward ported, tested and revised the driver:
 - Make it broadly textually similar to the Infineon and Nuvoton I2C
   driver
 - Place everything in a format suitable for mainline inclusion
 - Use high level I2C functions i2c_master_send and
   i2c_master_recv for data xfer
 - Use the timeout system from the core code, by faking out a status
   register
 - Only I2C transfer the number of bytes in the reply, not a fixed
   message size.
 - checkpatch cleanups
 - Testing on ARM Kirkwood, with this device tree, using a
   AT97SC3204T-X1A180
        tpm@29 {
                compatible = "atmel,at97sc3204t";

Originally written by Dan Morav <dmorav@nuvoton.com> and posted to LKML:
https://lkml.org/lkml/2011/9/7/206

The original posting was not merged, I have taken it as a
starting point, forward ported, tested and revised the driver:
 - Rework interrupt handling to work properly with level triggered
   interrupts. The old version just locked up.
 - Synchronize various items with Peter Huewe's Infineon driver:
    * Add durations/timeouts sysfs calls
    * Remove I2C device auto-detection
    * Don't fiddle with chip->release
    * Call tpm_dev_vendor_release in the probe error path
    * Use MODULE_DEVICE_TABLE for the I2C ids
    * Provide OF compatible strings for DT support
    * Use SIMPLE_DEV_PM_OPS
    * Use module_i2c_driver
 - checkpatch cleanups
 - Testing on ARM Kirkwood with GPIO interrupts, with this device tree:
	tpm@57 {
                compatible = "nuvoton,npct501";
                reg = <0x57>;
                interrupt-parent = <&gpio1>;

This driver adds support for Infineon's new SLB 9645 TT 1.2 I2C TPMs,
which supports clockstretching, combined reads and a bus speed of
up to 400khz. The device also has a new device id.

The driver works now also fine with device trees, so you can
instantiate your device by adding:
 +       tpm {
 +               compatible = "infineon,slb9645tt";
 +               reg = <0x20>;
 +       };
 for SLB 9645 devices or

 +       tpm {
 +               compatible = "infineon,slb9635tt";
 +               reg = <0x20>;
 +       };
 for SLB 9635 devices

to your device tree.
tpm_i2c_infineon is also retained as a compatible id as a fallback to
slb9635 protocol.

The driver was tested on Beaglebone.

Based on recent discussions, we apparently want to do bindings even for
trivial i2c devices, even though they have for years just been added. So
start a table of the currently known ones for others to be added to
over time.

to sort the file).
