2020-12-24sound: soc: fsl-spdif: Fix runtime PM imbalance on errorOleksandr Suvorov
In case of any error occurs after enabling the PM runtime framework for the fsl-spdif-dai device, the next probing generates the warning: "fsl-spdif-dai 2004000.spdif: Unbalanced pm_runtime_enable!" Add the error handling path to keep the PM runtime usage counter balanced. Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

2020-12-08i2c: imx: implement master_xfer_atomic callbackStefan Lengfeld
Rework the read and write code paths in the driver to support operation in atomic contexts. To achieve this, the driver must not rely on IRQs and not call schedule(), e.g. via a sleep routine, in these cases. With this patch the driver supports normal operation, DMA transfers and now the polling mode or also called sleep-free or IRQ-less operation. It makes the code not simpler or easier to read, but atomic I2C transfers are needed on some hardware configurations, e.g. to trigger reboots on an external PMIC chip.

2020-11-29ARM: dts: colibri-imx6ull: do not pull-up sd-clk but sd-cmd signalPhilippe Schenker
From the SD-Card specification: > The host shall supply power to the card so that the voltage is > reached to V DD _min within 250ms and start to supply at least > 74 SD clocks to the SD card with keeping CMD line to high. In case of > SPI mode, CS shall be held to high during 74 clock cycles. According to this information I think we should pull the CMD data line like on other boards to 3.3V.
