omapdrm: panel: fix compatible vendor string for td028ttec1

2018-03-24T10:00:25+00:00

[ Upstream commit c1b9d4c75cd549e08bd0596d7f9dcc20f7f6e8fa ]

The vendor name was "toppoly" but other panels and the vendor list
have defined it as "tpo". So let's fix it in driver and bindings.

We keep the old definition in parallel to stay compatible with
potential older DTB setup.

dt-bindings: mfd: axp20x: Add "xpowers,master-mode" property for AXP806 PMICs

2018-03-24T10:00:16+00:00

[ Upstream commit 8461cf20d17e0090e9236b73d25b31be4f7fadc5 ]

commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot")
was intended to fix the case where a board uses an AXP806 in slave mode,
but the boot loader leaves it in master mode for lack of AXP806 support.
But now the driver breaks on boards where the PMIC is operating in master
mode. To let the device tree describe which mode of operation is needed,
this patch introduces a new property "xpowers,master-mode".

arm: spear13xx: Fix dmas cells

2018-02-22T14:43:53+00:00

commit cdd10409914184c7eee5ae3e11beb890c9c16c61 upstream.

The "dmas" cells for the designware DMA controller need to have only 3
properties apart from the phandle: request line, src master and
destination master. But the commit 6e8887f60f60 updated it incorrectly
while moving from platform code to DT. Fix it.

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.
