* Merge tag 'imx-fixes-4.20-3' into imx7d/picoShawn Guo2018-12-101-2/+7
|\ | | | | | | | | | | | | | | | | i.MX fixes for 4.20, round 3: - A couple of fixes on imx7d-pico and imx7d-nitrogen7 boards to correct the description of the Wifi clock. - Change SW2ISO count to get a safer ARM LDO ramp-up time, so that different boards can be covered. This fixes the ARM LDO failure seen on some customer boards.
| * ARM: dts: imx7d-nitrogen7: Fix the description of the Wifi clockFabio Estevam2018-12-061-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | According to bindings/regulator/fixed-regulator.txt the 'clocks' and 'clock-names' properties are not valid ones. In order to turn on the Wifi clock the correct location for describing the CLKO2 clock is via a mmc-pwrseq handle, so do it accordingly.

* | ARM: dts: imx7: Fix memory node duplicationFabio Estevam2018-12-101-0/+1
|/ | | | | | | | | | | | | | | Boards based on imx7 have duplicate memory nodes: - One coming from the board dts file: memory@ - One coming from the imx7s.dtsi file. Fix the duplication by removing the memory node from the dtsi file and by adding 'device_type = "memory";' in the board dts.

* ARM: dts: imx7: Add "LPSR" to LPSR iomux pin namesSascha Hauer2017-01-291-7/+7
| | | | | | | | | | | | | The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr. In a board dts we have to make sure that both controllers are supplied with the correct pins. It's way too easy to do this wrong since only a look into the reference manual can reveal which pins belong to which controller. To make this clearer add "LPSR" to the pin names which belong to the LPSR controller.
