2018-12-24ARM: 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.

2018-12-24dts: 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>
2018-12-24dts: 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.

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.

2018-12-24ARM: dts: imx6: add required RS-485 propertiesStefan Agner
To operate RS-485 on Toradex Carrier Boards a low active RTS signal is required.

2018-12-24serial: 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>

2018-12-24ARM: 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.
