dt-bindings: usb: fix reg-property port-number range

2017-12-14T08:28:23+00:00

[ Upstream commit f42ae7b0540937e00fe005812997f126aaac4bc2 ]

The USB hub port-number range for USB 2.0 is 1-255 and not 1-31 which
reflects an arbitrary limit set by the current Linux implementation.

Note that for USB 3.1 hubs the valid range is 1-15.

Increase the documented valid range in the binding to 255, which is the
maximum allowed by the specifications.

hwmon: (jc42) optionally try to disable the SMBUS timeout

2017-12-05T10:24:34+00:00

commit 68615eb01f82256c19e41967bfb3eef902f77033 upstream.

With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver
is not always capable of avoiding the 25-35 ms timeout as specified by
the SMBUS protocol. This may cause silent corruption of the last bit of
any transfer, e.g. a one is read instead of a zero if the sensor chip
times out. This also affects the eeprom half of the nxp-se97 chip, where
this silent corruption was originally noticed. Other I2C adapters probably
suffer similar issues, e.g. bit-banging comes to mind as risky...

The SMBUS register in the nxp chip is not a standard Jedec register, but
it is not special to the nxp chips either, at least the atmel chips
have the same mechanism. Therefore, do not special case this on the
manufacturer, it is opt-in via the device property anyway.

clocksource/drivers/arm_arch_timer: Add dt binding for hisilicon-161010101 erratum

2017-11-08T09:08:35+00:00

[ Upstream commit 729e55225b1f6225ee7a2a358d5141a3264627c4 ]

This erratum describes a bug in logic outside the core, so MIDR can't be
used to identify its presence, and reading an SoC-specific revision
register from common arch timer code would be awkward.  So, describe it
in the device tree.
