Driver moxart-mmc.c has .compatible = "moxa,moxart-mmc". But moxart .dts/.dtsi and the documentation file moxa,moxart-dma.txt contain compatible = "moxa,moxart-sdhci". Change moxart .dts/.dtsi files and moxa,moxart-dma.txt to match the driver. Replace 'sdhci' with 'mmc' in names too, since SDHCI is a different controller from FTSDC010.

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.

We've found the AUX channel to be less reliable with PCLK_EDP at a higher rate (typically 25 MHz). This is especially important on systems with PSR-enabled panels (like Gru-Kevin), since we make heavy, constant use of AUX. According to Rockchip, using any rate other than 24 MHz can cause "problems between syncing the PHY an PCLK", which leads to all sorts of unreliabilities around register operations.

On SAMA7G5, when resuming from backup and self-refresh, the bootloader performs DDR PHY recalibration by restoring the value of ZQ0SR0 (stored in RAM by Linux before going to backup and self-refresh). It has been discovered that the current procedure doesn't work for all possible values that might go to ZQ0SR0 due to hardware bug. The workaround to this is to avoid storing some values in ZQ0SR0. Thus Linux will read the ZQ0SR0 register and cache its value in RAM after processing it (using modified_gray_code array). The bootloader will restore the processed value.

It has been discovered that on some parts, from time to time, self-refresh procedure doesn't work as expected. Debugging and investigating it proved that disabling AC DLL introduce glitches in RAM controllers which leads to unexpected behavior. This is confirmed as a hardware bug. DLL bypass disables 3 DLLs: 2 DX DLLs and AC DLL. Thus, keep only DX DLLs disabled. This introduce 6mA extra current consumption on VDDCORE when switching to any ULP mode or standby mode but the self-refresh procedure still works.
