Merge tag 'fixes-for-3.14d' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes:
Fourth set of IIO fixes for the 3.14 kernel.
A single line patch fixing a regression that was introduced in 3.13 in the
reworking of the mxs touch screen and ADC drivers to be interrupt rather
than polling driven. It resulted in a stray double reporting of the release
coordinate in the touch screen driver. The bug lay in the adc side
of the driver which left the statemachine in the wrong state.

+A successful call allocates ONE interrupt to the device, regardless

+pin-based interrupt mode to MSI mode. The dev->irq number is changed
+to a new number which represents the message signaled interrupt;

+request_irq(), because an MSI is delivered via a vector that is

+STMicroelectronics SoC DWMAC glue layer controller
+
+The device node has following properties.
+
+Required properties:
+ - compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac" or
+ "st,stid127-dwmac".
+ - reg : Offset of the glue configuration register map in system
+ configuration regmap pointed by st,syscon property and size.
+
+ - reg-names : Should be "sti-ethconf".
+
+ - st,syscon : Should be phandle to system configuration node which
+ encompases this glue registers.
+
+ - st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
+ wired up in from different sources. One via TXCLK pin and other via CLK_125
+ pin. This wiring is totally board dependent. However the retiming glue
+ logic should be configured accordingly. Possible values for this property
+
+ "txclk" - if 125Mhz clock is wired up via txclk line.
+ "clk_125" - if 125Mhz clock is wired up via clk_125 line.
+
+ This property is only valid for Giga bit setup( GMII, RGMII), and it is
+ un-used for non-giga bit (MII and RMII) setups. Also note that internal
+ clockgen can not generate stable 125Mhz clock.
+
+ - st,ext-phyclk: This boolean property indicates who is generating the clock
+ for tx and rx. This property is only valid for RMII case where the clock can
+ be generated from the MAC or PHY.
+
+ - clock-names: should be "sti-ethclk".
+ - clocks: Should point to ethernet clockgen which can generate phyclk.
+
+
+Example:
+
+ethernet0: dwmac@fe810000 {
+ device_type = "network";
+ compatible = "st,stih416-dwmac", "snps,dwmac", "snps,dwmac-3.710";

-The 3Com Etherlink Plus (3c505) driver.
-
-This driver now uses DMA. There is currently no support for PIO operation.
-The default DMA channel is 6; this is _not_ autoprobed, so you must
-make sure you configure it correctly. If loading the driver as a
-module, you can do this with "modprobe 3c505 dma=n". If the driver is
-linked statically into the kernel, you must either use an "ether="
-statement on the command line, or change the definition of ELP_DMA in 3c505.h.
-
-The driver will warn you if it has to fall back on the compiled in
-default DMA channel.
-
-If no base address is given at boot time, the driver will autoprobe
-ports 0x300, 0x280 and 0x310 (in that order). If no IRQ is given, the driver
-will try to probe for it.
-
-The driver can be used as a loadable module.
-
-Theoretically, one instance of the driver can now run multiple cards,
-in the standard way (when loading a module, say "modprobe 3c505
-io=0x300,0x340 irq=10,11 dma=6,7" or whatever). I have not tested
-this, though.
-
-The driver may now support revision 2 hardware; the dependency on
-being able to read the host control register has been removed. This
-is also untested, since I don't have a suitable card.
-
-Known problems:
- I still see "DMA upload timed out" messages from time to time. These
-seem to be fairly non-fatal though.
- The card is old and slow.
-
-To do:
- Improve probe/setup code
- Test multicast and promiscuous operation
-
-Authors:
- The driver is mainly written by Craig Southeren, email
- <craigs@ineluki.apana.org.au>.
- Parts of the driver (adapting the driver to 1.1.4+ kernels,
- IRQ/address detection, some changes) and this README by
- Juha Laiho <jlaiho@ichaos.nullnet.fi>.
- DMA mode, more fixes, etc, by Philip Blundell <pjb27@cam.ac.uk>
- Multicard support, Software configurable DMA, etc., by
- Christopher Collins <ccollins@pcug.org.au>
