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.

2022-09-29mwifiex: Select firmware based on strappingAndrejs Cainikovs
Some WiFi/Bluetooth modules might have different host connection options, allowing to either use SDIO for both WiFi and Bluetooth, or SDIO for WiFi and UART for Bluetooth. It is possible to detect whether a module has SDIO-SDIO or SDIO-UART connection by reading its host strap register. This change introduces a way to automatically select appropriate firmware depending of the connection method, and removes a need of symlinking or overwriting the original firmware file with a required one. Host strap register used in this commit comes from the NXP driver [1] hosted at Code Aurora.

2022-09-22drm/bridge: lt8912b: add vsync hsyncPhilippe Schenker
Currently the bridge driver does not take care whether or not the display needs positive/negative vertical/horizontal syncs. Pass these two flags to the bridge from the EDID that was read out from the display.

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.

2022-09-06Revert "drm/panel-simple: drop use of data-mapping property"Max Krummenacher
This reverts commit d021d751c14752a0266865700f6f212fab40a18c. Re-enable the data-mapping property which was already used in the 5.4-2.3.0 downstream kernel. In addition to the revert set bpc from the data-mapping value as a WARN_ON is printed if missing.

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.

2022-08-30Revert "drm/panel: panel-simple: use working pixelclock"Aishwarya Kothari
The change was supposed to workaround a SOC limitation, but changing the generic panel timing is not the correct solution. To fix this we will provide different timing using an overlay.
