2020-02-09iio: stmpe-adc: Use wait_for_completion_timeoutPhilippe Schenker
Use wait_for_completion_timeout instead of wait_for_completion_interuptible_timeout. The interruptible variant gets constantly interrupted if a user program is compiled with the -pg option. The killable variant was not used due to the fact that a second program, reading on this device, that gets killed is then also killing that wait.

2020-02-09iio: stmpe-adc: Enable all stmpe-adc interrupts just oncePhilippe Schenker
This commit will enable the interrupts of all channels handled by this driver only once in the probe function. This will improve performance because one byte less has to be written over i2c on each read out of the adc. On the fastest ADC mode this will improve read out speed by 15%.

2020-02-09iio: stmpe-adc: Reinit completion struct on begin conversionPhilippe Schenker
In some cases, the wait_completion got interrupted. This caused the error-handling to mutex_unlock the function. The before turned on interrupt then got called anyway. In the ISR then completion() was called causing wrong adc-values returned in a following adc-readout. Reinitialise completion struct to make sure the counter is zero when beginning a new adc-conversion.

2020-02-09net: can: flexcan: Add pinmuxing in runtime_supsendPhilippe Schenker
Due to the nature of CAN Tx/Rx pins have to be high when they are idle. After boot, CAN is put into runtime_suspend state. When using xceiver-supply in DT the power to the transceiver is turned off in this state. The Tx/Rx pins are then causing backfeeding. This patch adds selection of the sleep-state pins during runtime_suspend, so someone is able to define another muxing in this sate. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>

2020-02-09phy: micrel: do not use power down modeStefan Agner
Some Micrel KSZ8041NL PHY chips exhibit continous RX errors after using the power down mode bit (0.11). If the PHY is taken out of power down mode in a certain temperature range, the PHY enters a weird state which leads to continously reporting RX errors. In that state, the MAC is not able to receive or send any Ethernet frames and the activity LED is constantly blinking. Since Linux is using the suspend callback when the interface is taken down, ending up in that state can easily happen during a normal startup. Micrel confirmed the issue, caused by abnormal clock recovery when using power down mode. Even the latest revision (A4, Revision ID 0x1513) seems to suffer that problem. Remove the suspend/resume callback to avoid using the power down mode completely.

2020-02-09Input: atmel_mxt_ts - fix reset-gpio for level based irqsSebastian Reichel
The current reset-gpio support triggers an interrupt storm on platforms using the maxtouch with level based interrupt. The Motorola Droid 4, which I used for some of the tests is not affected, since it uses a edge based interrupt. This change avoids the interrupt storm by enabling the device while its interrupt is disabled. Afterwards we wait 100ms. This is important for two reasons: The device is unresponsive for some time (~22ms for mxt224E) and the CHG (interrupt) line is not working properly for 100ms. We don't need to wait for any following interrupts, since the following mxt_initialize() checks for bootloader mode anyways. This fixes a boot issue on GE PPD (watchdog kills device due to interrupt storm) and does not cause regression on Motorola Droid 4.

2020-02-09serial: imx: add RS-485 device tree propertiesStefan Agner
Add device tree properties to influence RTS polarity and whether the receiver is enabled during transmission (rs485-rts-active-low, rs485-rx-during-tx). This aligns with behavior with upstream Linux, where RTS is active high by default (SER_RS485_RTS_AFTER_SEND) and the receiver is disabled by default when using RS485 (SER_RS485_RX_DURING_TX). Note that for Toradex hardware both properties are required, hence using RS-485 on Toradex Carrier Boards requires the following properties being specified in the device tree: linux,rs485-enabled-at-boot-time; rs485-rts-active-low; rs485-rx-during-tx; Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com> (cherry picked from commit 72919eb5f9e7a9aeb5fc1c2aa694b07994fb5a8d) Conflicts: drivers/tty/serial/imx.c

2020-02-09ARM: imx7d: clk: make sure OCOTP clock is always onStefan Agner
Some device make use of the OCOTP via syscon. While the OCOTP node specifies a clock, in newer kernels the access via syscon does not enable the clock! During the main boot phase this is not usually a problem since the clock is initially on. However, after unused clocks get disabled, any access leads to a freeze. This has been observed when the i.MX Thermal driver probe has been deferred: The driver tried to read the calibration data from OCOTP via syscon and caused a system freeze. In upstream Linux this has recently been resolved using the NVMEM framework, see: Commit ae6215576d6b ("thermal: imx: Add support for reading OCOTP through nvmem") Commit a6c856e9a8cd ("ARM: dts: imx6sx: Use nvmem-cells for tempmon") Use a simpler work around by just adding the clock to the list of clocks which should kept on.

Add a kernel parameter ("gpio-mxc.noclearirq") to disable unconditional interrupt mask/clearing. This is useful when a second CPU (the Cortex-M4) is accessing the same GPIO bank. Using the same GPIO bank from the Cortex-A7 and M4 sounds risky, but it seems to work quite well. Most registers are write only (e.g. interrupt status register can be cleared with a single write), which makes them safe for concurrent access. However, sharing a single GPIO bank between two cores does not allow to use the Resource Domain Controller. Hence for secure applications assigning a dedicated GPIO bank is still preferable.

2020-02-09mxc_v4l2_capture: Change error message to print on debugSanchayan Maity
Change the "unsupported ioctrl" message to print only on debug. This otherwise results in an error message ERROR: v4l2 capture: unsupported ioctrl! which does not seem to effect the gstreamer pipeline or rendering of video. >From debugging, root@apalis-imx6:~# gst-launch-1.0 imxv4l2videosrc ! imxeglvivsink Setting pipeline to PAUSED ...

"The V4L2_CID_3A_LOCK bitmask control allows applications to pause or resume the automatic exposure, focus and wite balance adjustments. It can be used, for example, to lock the 3A adjustments right before a still image is captured, for pre-focus, etc. The applications can control each of the algorithms independently, through a corresponding control bit, if driver allows that." https://patchwork.linuxtv.org/patch/10719/ Since we have no such feature available we can safely disable the error message.

2020-02-09mxc_v4l2_capture: Allow clock setting for de-interlaced video inputSanchayan Maity
Make provision for a decoder driver to specify clock mode for progressive in case the decoder provides deinterlaced output. This is required for ADV7280 decoder where we can use the hardware deinterlace capabity of ADV7280. Without setting the clock mode to progressive but having hardware deinterlace on for ADV7280 results in a non working setup.

2020-02-09tty: serial: imx: disable DCD and RI interruptsStefan Agner
If the UART is in DTE mode, the signals DCD and RI are inputs. In this case, the control bits in UCR3_DCD and UCR3_RI control the interrupt of those two inputs. The two bits are 1 on reset, hence leading to an interrupt if one of those signal changes... However, as of now the interrupt handler does not handle these interrupts, leading to a interrupt strom. Solve the issue by explicitly disabling the two interrupts during initialization.

2020-02-09PCI: Apalis GEN1 forcing quirkMarcel Ziswiler
The Apalis evaluation board needs to set the link speed to 2.5 GT/s (GEN1). The default link speed setting is 5 GT/s (GEN2). 0x98 is the Link Control 2 PCIe Capability Register of the PEX8605 PCIe switch. The switch supports link speed auto negotiation, but falsely sets the link speed to 5 GT/s.
