Pull char/misc driver updates from Greg KH: "Here is the big char/misc driver patchset for 4.11-rc1. Lots of different driver subsystems updated here: rework for the hyperv subsystem to handle new platforms better, mei and w1 and extcon driver updates, as well as a number of other "minor" driver updates. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (169 commits) goldfish: Sanitize the broken interrupt handler x86/platform/goldfish: Prevent unconditional loading vmbus: replace modulus operation with subtraction vmbus: constify parameters where possible vmbus: expose hv_begin/end_read vmbus: remove conditional locking of vmbus_write vmbus: add direct isr callback mode vmbus: change to per channel tasklet vmbus: put related per-cpu variable together vmbus: callback is in softirq not workqueue binder: Add support for file-descriptor arrays binder: Add support for scatter-gather binder: Add extra size to allocator binder: Refactor binder_transact() binder: Support multiple /dev instances binder: Deal with contexts in debugfs binder: Support multiple context managers binder: Split flat_binder_object auxdisplay: ht16k33: remove private workqueue auxdisplay: ht16k33: rework input device initialization ...

+ 89hpes48t12, 89hpes48t12g2.
+ - reg : I2C address of the IDT 89HPESx device.
+
+Optionally there can be EEPROM-compatible subnode:
+ - compatible: There are five EEPROM devices supported: 24c32, 24c64, 24c128,
+ 24c256 and 24c512 differed by size.
+ - reg: Custom address of EEPROM device (If not specified IDT 89HPESx
+ (optional) device will try to communicate with EEPROM sited by default
+ address - 0x50)
+ - read-only : Parameterless property disables writes to the EEPROM
+ (optional)
+
+Example:
+ idt@60 {
+ compatible = "idt,89hpes32nt8ag2";
+ reg = <0x74>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ eeprom@50 {
+ compatible = "onsemi,24c64";
+ reg = <0x50>;
+ read-only;
+ };
+ };
