2022-11-03Revert "arm64: dts: imx8mp-verdin: limit sdio wi-fi frequency to 100 mhz"Marcel Ziswiler
This reverts commit 9f04e0d3d5603fee7648dfac6713a29478686932. As we found the real instability having been due to a contention between the async SDIO interrupt and the auto-tuning, no longer limit the SDIO frequency to 100 MHz.

2022-11-03arm64: dts: imx8mp-verdin: fix sdio wifi instabilityMarcel Ziswiler
Fix SDIO Wi-Fi instability by adding fsl,sdio-async-interrupt-enabled device tree property to the usdhc1 instance connected to the on-module AW-CM276NF Wi-Fi. From Documentation/devicetree/bindings/mmc/fsl-imx-esdhc.yaml: Recommend for SDIO cards that enables SDIO async interrupt for SDR104 and SDR50 operating modes. SDIO async interrupt uses DAT[1] to signal the card's interrupt. uSDHC tuning mechanism must use DAT[0] and CMD signals to avoid a possible conflict and incorrect delay line calculated by the uSDHC auto tuning mechanism. Enabling this device tree property is only recommended for layouts that are matching the SD interface length.

2022-09-22arm64: dts: imx8mp-verdin: fix ctrl_sleep_mociMax Krummenacher
The GPIO signaling ctrl_sleep_moci is currently handled as a gpio hog. But the gpio-hog node is made a child of the wrong gpio controller. Move it to the node representing gpio4 so that it actually works. Without this carrier board components jumpered to use the signal are unconditionally switched off.

2022-09-05Revert "arm64: dts: imx8mp-verdin: prevent emmc crash"Max Krummenacher
This reverts commit 96084b8822418f30ff0b941bfe7222d7e941090d. The kernel panic was due to U-Boot not (yet) setting the DDR RAM size dynamically depending on the SKU but setting it to the maximum of 8GB. The kernel crashes when it first tries to access not existing RAM addresses.

2022-09-05toradex_defconfig: verdin-imx8mp: fix concurrent use of dsi and native hdmiMax Krummenacher
With native HDMI being a kernel built in and the DSI adapters being a module, concurrent use of the two leads to a not booting kernel. When DRM tries to bring up native HDMI it also tries to bring up the bridge to DSI which then returns EAGAIN as the DSI to HDMI/LVDS kernel modules cannot be loaded yet. This results in a never ending loop rather than continuing to init and trying again. Compiling the bridge to DSI as a module fixes the issue.

2022-09-01arm64: dts: imx8mm-verdin: extend pmic voltagesPhilippe Schenker
Currently, we limited the voltages from the PMIC very strictly. This causes an issue with one Toradex SKU that uses a consumer-grade chip that is capable of going up to 1.8GHz at 1.00V. Extend the ranges to min/max values of the SoC operating ranges (table 10) in the datasheet. Detailed explanation as follows: BUCK2: - As already described above, the SKU with the consumer-grade chip needs a voltage of at least 1.00V. 1.05V is chosen now as this is listed as the maximum. Both industrial and consumer-grade chips have an absolute maximum rating of 1.15V which makes it still safe to put 1.05V - Lower the regulator-min value to the smallest value allowed from the Quad-A53, 1.2GHz version of the SoC BUCK3: - This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and VDD_DRAM. - Use the smallest value of these three inputs as the regulator-min - Use the largest value of these three inputs as the regulator-max LDO2: - This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a single nominal input voltage just put this in the middle of 0.8V.

2022-08-03arm64: dts: verdin-imx8mm: add otg2 pd to usbphyPhilippe Schenker
The Verdin iMX8M Mini System on Module does not have VBUS signal connected on Verdin USB_2 (usbotg2). On Verdin Development board this is no problem, as we have connected a USB-Hub that is always connected. However, if Verdin USB_2 is desired to be used as a single USB-Host port the chipidea driver does not detect if a USB device is plugged into this port, due to runtime pm shutting down the PHY. Add the power-domain &pgc_otg2 to &usbphynop2 in order to detect plugging events and enumerate the usb device.

2022-07-28arm64: dts: freescale: add initial support for verdin imx8m plusMarcel Ziswiler
This patch adds the device tree to support Toradex Verdin iMX8M Plus [1] a computer on module which can be used on different carrier boards. The module consists of an NXP i.MX 8M Plus family SoC (either i.MX 8M Plus Quad or 8M Plus QuadLite), a PCA9450C PMIC, a Gigabit Ethernet PHY, 1, 2, 4 or 8 GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an RX8130 RTC, an optional I2C temperature sensor plus an optional Bluetooth/Wi-Fi module. Anything that is not self-contained on the module is disabled by default. The device tree for the Dahlia includes the module's device tree and enables the supported peripherals of the carrier board. The device tree for the Verdin Development Board includes the module's device tree as well as the Dahlia one as it is a superset and supports almost all peripherals available. So far there is no display functionality supported at all but basic console UART, USB host, eMMC and Ethernet functionality work fine.
