+Subject: iio: adc: ad7606: fix serial register access
+
+From: Angelo Dureghello <adureghello@baylibre.com>
+
+commit f083f8a21cc785ebe3a33f756a3fa3660611f8db upstream.
+
+Fix register read/write routine as per datasheet.
+
+When reading multiple consecutive registers, only the first one is read
+properly. This is due to missing chip select deassert and assert again
+between first and second 16bit transfer, as shown in the datasheet
+AD7606C-16, rev 0, figure 110.

+Subject: iio: adis16201: Correct inclinometer channel resolution
+
+From: Gabriel Shahrouzi <gshahrouzi@gmail.com>
+
+commit 609bc31eca06c7408e6860d8b46311ebe45c1fef upstream.
+
+The inclinometer channels were previously defined with 14 realbits.
+However, the ADIS16201 datasheet states the resolution for these output
+channels is 12 bits (Page 14, text description; Page 15, table 7).
+
+Correct the realbits value to 12 to accurately reflect the hardware.

+Subject: usb: uhci-platform: Make the clock really optional
+
+From: Alexey Charkov <alchark@gmail.com>
+
+commit a5c7973539b010874a37a0e846e62ac6f00553ba upstream.
+
+Device tree bindings state that the clock is optional for UHCI platform
+controllers, and some existing device trees don't provide those - such
+as those for VIA/WonderMedia devices.
+
+The driver however fails to probe now if no clock is provided, because
+devm_clk_get returns an error pointer in such case.
+
+Switch to devm_clk_get_optional instead, so that it could probe again
+on those platforms where no clocks are given.
