2018-10-31apalis-imx8qm: enable sataMarcel Ziswiler
Add external clock nodes to model the on-module SATA reference clock generator. Assign it to the SATA instance so it can be disabled if required. Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2018-10-31ata: imx: add external clock support for i.MX8QMMarcel Ziswiler
Add external reference clock via clock tree. This allows to model the shared reference clock provided via PCIE_SATA_REFCLK100M_P/N properly. This is analogous to what we did for PCIe in commit db22e7590338 ("PCI: imx6: add external clock support for i.MX8QM"). Signed-off-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

2018-06-15MLK-18433 PCI: imx: remove the lpcg_xxx clocks in driverRichard Zhu
Remove the lpcg_xxx clocks codes, since they are HW gated. These clocks controlled by HW, and would be turned on automatically, if there are access operations. Signed-off-by: Richard Zhu <hongxing.zhu@nxp.com>

2018-05-23imx8: 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.
2018-05-23imx8: 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.
2018-05-23imx8: csi: Recognize all yuv formats as yuvTomasz Gorochowik
Make the get_src_fmt callback treat all yuv formats equally. This is needed to recognize the actual source format as yuv and enable yuv->rgb conversion in the image processing unit of iMX8.
2018-05-23imx8: csi: Implement proper subdev accessTomasz Gorochowik
Until now, the device searched for the subdev (sensor dev) using the device name. That was a hack and required a hard-coded name of the device in the common code. This commit fixes it and makes it look for the proper subdevice using the media pads layer.
2018-05-23imx8: csi: Fix off-by-one error in sensors enumerationTomasz Gorochowik
Sensor ID counter starts from 0 while the actual device number starts from 1. Fix the issue that it caused. Without this fix it is impossible to make proper media pads connections.

2018-05-23dtb: apalis-imx8qm: Add proper ov5640 instantiationTomasz Gorochowik
This commit makes the camera instantiation use the proper driver and fixes all the settings so it works with Apalis.
2018-05-23drivers: media: Add new ov5640 driverTomasz Gorochowik
This driver is a copy of a driver by nVidia. It was improved by Antmicro for the TK1 board. Additionally there are some changes which were required to make it compatible with iMX8.
2018-05-16apalis-imx8qm: disable LVDS by defaultStefan Agner
LVDS is treated as primary display by the kernel. So when both is enabled, HDMI and LVDS, then LVDS is the primary display. Hence demos using only one screen usually do not show anything on HDMI. Since HDMI is used more often, and most customers probably do not have a matching LVDS display at hand, disable LVDS by default for now. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
2018-05-02arm64: defconfig: add SGTL5000 supportStefan Agner
Add NXP SGTL5000 codec support for Apalis iMX8. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
2018-05-02apalis-imx8qm: add audio support through SGTL5000 codecStefan Agner
Add SAI1 I2S peripheral and SGTL5000 audio codec support for on-module audio support. Note that clocking is currently setup in the SGTL5000 codec node, altough it seems that due to cross dependencies those clocks (or root clocks thereof) might get changed later on. With the current clock frequencies audio seems to play at the correct rate. The power rails need further refinement. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

2018-05-02rtc: ds1307: support m41t0 variantStefan Agner
The m41t0 variant is very similar to the already supported m41t00 variant, with the notable exception of the oscillator fail bit. The data sheet notes: If the oscillator fail (OF) bit is internally set to a '1,' this indicates that the oscillator has either stopped, or was stopped for some period of time and can be used to judge the validity of the clock and date data. The bit will get cleared with a regular write of the system time, so no changes are needed to clear it.

2018-02-20ARM64: dts: fsl-imx8qm: use X2 peripheral clock on both instancesStefan Agner
When pciea fails to probe, it disables X2 peripheral clock. When pcieb probes subsequently, the kernel crashes with a "Unhandled fault: synchronous external abort" in regmap_mmio_read32le. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

When the second controller initializes PCIe while the first failed to initialize, the X2 peripheral clock will be off.

2018-02-19apalis-imx8qm: it seems that X2 peripheral clock is requiredStefan Agner
When pciea fails to probe, it disables X2 peripheral clock. Then when pcieb probes, the kernel crashes with various errors, but most often with a "Unhandled fault: synchronous external abort" in regmap_mmio_read32le. In contrast, X1 peripheral clock seems not to be required... Use just X2 on both PCIe instances. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>

When using a GPIO which is high by default, and initialize the driver in USB Hub mode, initialization fails with: [ 111.757794] usb3503 0-0008: SP_ILOCK failed (-5) The reason seems to be that the chip is not properly reset.
