Reduce the current drawn from VCC_BATT when the main power on the 3V3 pins to the module are switched off. This switches off SoC internal pull resistors which are provided on the module for TAMPER7 and TAMPER9 SoC pin and switches on a pull down instead of a pullup for the USBC_DET module pin (TAMPER2).

2018-09-27ARM: dts: imx7-colibri: disable HS400Stefan Agner
Force HS200 by masking bit 63 of the SDHCI capability register. The i.MX ESDHC driver uses SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400. With that the stack checks bit 63 to descide whether HS400 is available. Using sdhci-caps-mask allows to mask bit 63. The stack then selects HS200 as operating mode. This prevents rare communication errors with minimal effect on performance: sdhci-esdhc-imx 30b60000.usdhc: warning! HS400 strobe DLL status REF not lock!

2018-09-27mmc: sdhci: Use sdhci-caps-mask and sdhci-caps to change the caps read ↵Zach Brown
during __sdhci_read_caps The sdhci capabilities register can be incorrect. The sdhci-caps-mask and sdhci-caps dt properties specify which bits of the register are incorrect and what their values should be. This patch makes the sdhci driver use those properties to correct the caps during __sdhci_read_caps. During __sdhci_read_caps Use the sdhci-caps-mask property to turn off the incorrect bits of the sdhci register after reading them. Use the sdhci-caps to turn on bits after using sdhci-caps-mask to turn off the incorrect ones.

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.

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>

SDHCI falls back to fixed sampling if there is an error during tuning. However it also reports an error unless there is periodic re-tuning. That is not the best option because: a) there is a reasonable chance that fixed sampling will work, especially at room temperature. b) re-tuning will be done again anyway if there are CRC errors.
