Using regmap update bits the way it was used is wrong as only additional bits gets set but no bits would be cleared. The whole register or NRD and PDS are reserved for those two function.

2020-02-09imx8: isi: XXX: Add code to force format setting in the actual sensorTomasz Gorochowik
This commit adds code that forces setting the requested format in the actual sensor driver. Note that currently it is commented out as imx8 isi does not seem to work properly with any other source resolution than the default 1920x1080. Without this code, the driver will work with other resolutions (the ones which are reported as supported by the connected sensors and lower than 1920x1080), but the image will be scaled down from 1920x1080. Scaling up is not supported.

2020-02-09imx8: isi: Disable scaling when not neededTomasz Gorochowik
The issue is that once the scaling was enabled, then the stream was disabled and enabled again with a resolution that does not need scaling, the actual scaling was never disabled in the ISI block. This made ISI stream the scaled down with a large black padding.

2020-02-09imx_thermal.c: Use old trip point values from BSP 2.7Philippe Schenker
In kernel upgrade from 4.1 -> 4.9 trip point values have been changed by NXP. These new values caused a lot of modules to critical shut-down during validation and verification. This commit changes the new imx_thermal.c code to use the old, well verified values.

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.

2020-02-09video: fbdev: mxsfb: fix pixelclock polarityStefan Agner
The PIXDATA flags of the display_flags enum are controller centric, e.g. NEGEDGE means the controller shall drive the data signals on pixelclocks negative edge. However, the drivers flag is display centric: Sample the data on negative (falling) edge. Therefore, change the if statement to check for the POSEDGE flag (which is typically not set): Drive on positive edge => sample on negative edge Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com> (cherry picked from commit 5652dc1ad78303fb246f050ba23c563319d823cf)
