The bootrom burned into the MT7986 SoC will try multiple locations on the SPI-NAND flash to load bl2 in case the bl2 image located at the the previously attempted offset is corrupt. Use 0x100000 instead of 0x80000 as partition size for bl2 on SPI-NAND, allowing for up to four redundant copies of bl2 (typically sized a bit less than 0x40000).

Add the GPU's OPP table. This is from the downstream ChromeOS kernel, adapted to the new upstream opp-supported-hw binning format. Also add dynamic-power-coefficient for the GPU. Also add label for mfg1 power domain. This is to be used at the board level to add a regulator supply for the power domain. Signed-off-by:

The capacity-dmips-mhz parameter was miscalculated: this SoC runs the first (Cortex-A55) cluster at a maximum of 2000MHz and the second (Cortex-A76) cluster at a maximum of 2200MHz. In order to calculate the right capacity-dmips-mhz, the following test was performed: 1. CPUFREQ governor was set to 'performance' on both clusters 2. Ran dhrystone with 500000000 iterations for 10 times on each cluster 3. Calculated the mean result for each cluster 4. Calculated DMIPS/MHz: dmips_mhz = dmips_per_second / cpu_mhz 5. Scaled results to 1024: result_c0 = dmips_mhz_c0 / dmips_mhz_c1 * 1024 The mean results for this SoC are: Cluster 0 (LITTLE): 12016411 Dhry/s Cluster 1 (BIG): 31702034 Dhry/s The calculated scaled results are: Cluster 0: 426.953226899238 (rounded to 427) Cluster 1: 1024 Fixes: 48489980 ("arm64: dts: Add Mediatek SoC MT8192 and evaluation board dts and Makefile") Signed-off-by:

In the series "Adjust the dma-ranges for MTK IOMMU", the mtk-iommu driver was adapted to separate the iova range based on the larb used, and a dma-ranges property was added to the soc node in the devicetree of the affected SoCs allowing the whole 16GB iova range to be used. Except that for mt8192, there was no patch adding dma-ranges. Add the missing dma-ranges property to the soc node like was done for mt8195 and mt8186. This fixes the usage of the vcodec, which would otherwise trigger iommu faults. Signed-off-by:

Currently a specific panel number is used in the Elm DTSI, which is corresponded to a 12" panel. However, according to the official Chrome OS devices document, Elm refers to Acer Chromebook R13, which, as the name specifies, uses a 13.3" panel, which comes with EDID information. As the kernel currently prioritizes the hardcoded timing parameters matched with the panel number compatible, a wrong timing will be applied to the 13.3" panel on Acer Chromebook R13, which leads to blank display. Because the Elm DTSI is shared with Hana board, and Hana corresponds to multiple devices from 11" to 14", a certain panel model number shouldn't be present, and driving the panel according to its EDID information is necessary.

To store uncompressed bl2 more space is required than partition is actually defined. There is currently no known usage of this reserved partition. Openwrt uses same partition layout.

Note that despite there being two interrupts, one for MT6331 and one for MT6332, in configurations using the companion PMIC, the interrupt of the latter fires for both events on MT6331 and for ones on MT6332, while the interrupt for the main PMIC fires only for events of the main PMIC.
