Merge tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2017-05-06T01:16:23Z

Pull staging/IIO updates from Greg KH: "Here is the big staging tree update for 4.12-rc1. It's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree" Merge conflicts in the new rtl8723bs driver (due to the wifi changes this merge window) handled as per linux-next, courtesy of Stephen Rothwell. * tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1182 commits) staging: fsl-mc/dpio: add cpu <--> LE conversion for dpaa2_fd staging: ks7010: remove line continuations in quoted strings staging: vt6656: use tabs instead of spaces staging: android: ion: Fix unnecessary initialization of static variable staging: media: atomisp: fix range checking on clk_num staging: media: atomisp: fix misspelled word in comment staging: media: atomisp: kmap() can't fail staging: atomisp: remove #ifdef for runtime PM functions staging: atomisp: satm include directory is gone atomisp: remove some more unused files atomisp: remove hmm_load/store/clear indirections atomisp: kill off mmgr_free atomisp: clean up the hmm init/cleanup indirections atomisp: handle allocation calls before init in the hmm layer staging: fsl-dpaa2/eth: Add maintainer for Ethernet driver staging: fsl-dpaa2/eth: Add TODO file staging: fsl-dpaa2/eth: Add trace points staging: fsl-dpaa2/eth: Add driver specific stats staging: fsl-dpaa2/eth: Add ethtool support staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver ...

iio: adc: add max1117/max1118/max1119 ADC driver

2017-04-14T14:09:06Z

This adds max1117/max1118/max1119 8-bit, dual-channel ADC driver. This new driver uses the zero length spi_transfers with the cs_change flag set and/or the non-zero delay_usecs. 1. The zero length transfer with the spi_transfer.cs_change set is required in order to select CH1. The chip select line must be brought high and low again without transfer. 2. The zero length transfer with the spi_transfer.delay_usecs > 0 is required for waiting the conversion to be complete. The conversion begins with the falling edge of the chip select. During the conversion process, SCLK is ignored. These two usages are unusual. But the spi controller drivers that use a default implementation of transfer_one_message() are likely to work. (I've tested this adc driver with spi-omap2-mcspi and spi-xilinx) On the other hand, some spi controller drivers that have their own transfer_one_message() may not work. But at least for the zero length transfer with delay_usecs > 0, I'm proposing a new testcase for the spi-loopback-test that can test whether the delay_usecs setting has taken effect.

iio: xoadc: augment DT bindings a bit

2017-04-08T16:40:07Z

In order to accommodate in a logical manner for the premuxed channels in PM8921 and the similarly addressed channels in later PMICs, we need a twocell arrangement with premux and analog mux setting as a tuple to uniquely identify a hardware channel. These bindings are not yet in use, so it should be fine to augment them before we actually start using it in drivers and device trees. This scheme came out of lengthy discussions and reverse-engineering and reading of the few information sources we have.

iio:adc: Driver for Linear Technology LTC2497 ADC

2017-04-02T09:56:59Z

This patch adds support for the Analog Devices / Linear Technology LTC2497 ADCs. The LTC2497 is a 16-channel (eight differential), 16-bit, high precision, delta-sigma ADC with an automatic, differential, input current cancellation front end and a 2-wire, I2C interface.

iio:imu:mpu6050 add explicit mpu9250 support

2017-04-02T09:12:08Z

The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all there was too it there would be no need for explicit handling in the driver. Arguably the bindings would also only reflect the presence of an mpu6500 with the ak8975 hanging off it, as the kernel doesn't care that they are in one package. However, the WHOAMI value changes as well so best to add explicit support. Signed-off-by: Jonathan Cameron

iio:imu:mpu6050 update i2c bindings to reflect i2c-gate and supported parts

2017-04-02T09:09:20Z

These bindings are somewhat lagging the state of the driver. The i2c-gate bindings are documented elsewhere, but it seems sensible to at least have an example and cross reference in here. SPI bindings will need to be the subject of a future patch. Signed-off-by: Jonathan Cameron Acked-by: Rob Herring
