2019-03-12ARM: dts: Add sleep state to the sd-card pinsPhilippe Schenker
This commit adds a sleep state to the ixora devicetree. This prevents backfeeding when sending the module to any sleep state. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2019-03-12net: 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>

2018-12-27phy: 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.

2018-12-27Input: 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.

2018-12-24ASoC: sgtl5000: Allow LRCLK pad drive strength to be changedFabio Estevam
Introduce the "lrclk-strength" property to allow LRCLK pad drive strength to be changed via device tree. When running a stress playback loop test on a mx6dl wandboard channel swap can be noticed on about 10% of the times. While debugging this issue I noticed that when probing the SGTL5000 LRCLK pin with the scope the swap did not happen. After removing the probe the swap started to happen again. After changing the LRCLK pad drive strength to the maximum value the issue is gone. Same fix works on a mx6dl Colibri board as well.
