2018-12-09ARM: dts: Coibri iMX6ULL: use wdog HW signal for resetMax Krummenacher
The i.MX6 ULL's watchdog is used to reset the SoC on reboot. The watchdog is configured to use the SoC's internal reset signal which does not generate a reset pulse on nRESET_OUT. Change the watchdog configuration to use a SoC external HW signal. This will additionally change the 'Reset cause' message from U-Boot from WDOG to POR.

2018-12-09ARM: dts: imx6: mux SD/MMC CD and SPI CS explicitlyStefan Agner
Use a pinmux configuration for SD/MMC card detect and SPI chip select instead of relying on reset/boot settings. There have been no adverse effects observed, but it seems sensible to mux the pads explicitly.

The device tree got changed to use the simple card driver, so enable it in the defconfig. While at it remove the IMX_SGTL5000 driver now replaced by the simple card driver. While at it remove the unused ESAI driver. While at it remove the unused CS42XX8_I2C codec driver.

2018-12-09dts: imx: colibri eval/iris: change pins to capacitive touch adapterMax Krummenacher
The Capacitive Touch Adapter is an interface board designed to easily connect the Capacitive Touch Display 7" Parallel to the Colibri Carrier boards which do not have PCAP connector yet available on board. Change the pins for interrupt and reset to those defined in the Capacitive Touch Adapter's datasheet. While at it remove the '#ifdef PCAP' in favour of disabled nodes. That way one can fixup the device tree in U-Boot to disable the pwm nodes and enable the connected touch controller. e.g. for a Colibri iMX6S/DL: Colibri iMX6 # setenv fdt_fixup 'fdt addr ${fdt_addr_r} && fdt resize && fdt set /soc/aips-bus@02100000/i2c@021a8000/atmel_mxt_ts@4a status okay; fdt set /soc/aips-bus@02000000/pwm@02080000 status disabled; fdt set /soc/aips-bus@02000000/pwm@0208c000 status disabled' Colibri iMX6 # saveenv Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
2018-12-09dts: imx: fix M41T0 RTC compatible stringGerard Salvatella
Toradex Carrier boards use the ST M41T0 RTC (not M41T00). The RTC is almost the same, but the M41T0 needs some special handling in case the oscillator fails. Now that support for this difference is available, using the new compatible string to make use of it.

2018-12-09ARM: dts: imx6qdl: Fix SPDIF regressionFabio Estevam
Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") changed many more clocks than only the SPDIF core clock as stated in the commit message. The MLB clock has been added and this causes SPDIF regression as reported by Xavi Drudis Ferran and also in this forum post: https://forum.digikey.com/thread/34240 The MX6Q Reference Manual does not mention that MLB is a clock related to SPDIF, so change it back to a dummy clock to restore SPDIF functionality. Thanks to Ambika for providing the fix at: https://community.nxp.com/thread/387131 Fixes: 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif") Cc: <stable@vger.kernel.org> # 4.4.x Reported-by: Xavi Drudis Ferran <xdrudis@tinet.cat> Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Tested-by: Xavi Drudis Ferran <xdrudis@tinet.cat> Signed-off-by: Shawn Guo <shawnguo@kernel.org> (cherry picked from commit f065e9e4addd75c21bb976bb2558648bf4f61de6) This fix was correct, but overwritten by commit 833f2cbf7091099baee28136dc68678e974c0ac5.
