2023-06-15arm64: dts: mediatek: mt8192: Fix CPUs capacity-dmips-mhzNícolas F. R. A. Prado
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: 48489980e27e ("arm64: dts: Add Mediatek SoC MT8192 and evaluation board dts and Makefile") Signed-off-by: Nícolas F.

2023-06-15arm64: dts: mediatek: mt8192: Add missing dma-ranges to soc nodeNícolas F. R. A. Prado
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: Nícolas F. R. A.

2023-06-15arm64: dts: mediatek: mt8173-elm: remove panel model number in DTIcenowy Zheng
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.

2023-06-15KVM: arm64: Fix hVHE init on CPUs where HCR_EL2.E2H is not RES1Marc Zyngier
On CPUs where E2H is RES1, we very quickly set the scene for running EL2 with a VHE configuration, as we do not have any other choice. However, CPUs that conform to the current writing of the architecture start with E2H=0, and only later upgrade with E2H=1. This is all good, but nothing there is actually reconfiguring EL2 to be able to correctly run the kernel at EL1. Huhuh... The "obvious" solution is not to just reinitialise the timer controls like we do, but to really intitialise *everything* unconditionally. This requires a bit of surgery, and is a good opportunity to remove the macro that messes with SPSR_EL2 in init_el2_state. With that, hVHE now works correctly on my trusted A55 machine!

2023-06-15arm64: dts: ti: k3-j7200: Configure pinctrl for timer IO padsUdit Kumar
There are timer IO pads in the MCU domain, and in the MAIN domain. These pads can be muxed for the related timers. There are timer IO control registers for input and output. The registers for CTRLMMR_TIMER*_CTRL and CTRLMMR_MCU_TIMER*_CTRL are used to control the input. The registers for CTCTRLMMR_TIMERIO*_CTRL and CTRLMMR_MCU_TIMERIO*_CTRL the output. The multiplexing is documented in TRM "5.1.2.3.1.4 Timer IO Muxing Control Registers" and "5.1.3.3.1.5 Timer IO Muxing Control Registers", and the CASCADE_EN bit is documented in TRM "12.6.3.1 Timers Overview". For chaining timers, the timer IO control registers also have a CASCADE_EN input bit in the CTRLMMR_TIMER*_CTRL in the registers. The CASCADE_EN bit muxes the previous timer output, or possibly and external TIMER_IO pad source, to the input clock of the selected timer instance for odd numered timers. For the even numbered timers, the CASCADE_EN bit does not do anything. The timer cascade input routing options are shown in TRM "Figure 12-3224. Timers Overview". For handling beyond multiplexing, the driver support for timer cascading should be likely be handled via the clock framework. The MCU timer controls are also marked as reserved for usage by the MCU firmware.

There are 20 general purpose timers on j721e that can be used for things like PWM using pwm-omap-dmtimer driver. There are also additional ten timers in the MCU domain which are meant for MCU firmware usage and hence marked reserved by default. The odd numbered timers have the option of being cascaded to even timers to create a 64 bit non-atomic counter which is racy in simple usage, hence the clock muxes are explicitly setup to individual 32 bit counters driven off system crystal (HFOSC) as default.

2023-06-15arm64: dts: ti: k3-am64: Use phandle to stdout UART nodeAndrew Davis
Using a phandle makes it clear which UART we are choosing without needing to resolve through an alias first. Especially useful for boards like the TI J721s2-EVM where the alias is "serial2" but it actually resolves to the 8th UART instance(main_uart8).

2023-06-15arm64: dts: ti: k3-am64: Only set UART baud for used portsAndrew Davis
As the binding for "current-speed" states, this should only be used when the baud rate of an attached device cannot be detected. This is the case for our attached on-board USB-to-UART converter used for early kernel console. For all other unconnected/disabled ports this can be configured in userspace later, DT is not the place for device configuration, especially when there are already standard ways to set serial baud in userspace. Remove setting baud for all disabled serial ports and move setting it for the couple enabled ports down into the board files.

main_i2c0 is aliased as i2c0 which creates a problem for u-boot R5 SPL attempting to reuse the same definition in the common board detection logic as it looks for the first i2c instance as the bus on which to detect the eeprom to understand the board variant involved. Switch main_i2c0 to i2c3 alias allowing us to introduce wkup_i2c0 and potentially space for mcu_i2c instances in the gap for follow on patches.

The wkup_pmx register region in j784s4 has multiple non-addressable regions, hence the existing wkup_pmx region is split as follows to avoid the non-addressable regions. The pinctrl node offsets are also corrected as per the newly split wkup_pmx* nodes. wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12) wkup_pmx1 -> 11 pins (WKUP_PADCONFIG 14 - 24) wkup_pmx2 -> 72 pins (WKUP_PADCONFIG 26 - 97) wkup_pmx3 -> 1 pin (WKUP_PADCONFIG 100) Fixes: 4664ebd8346a ("arm64: dts: ti: Add initial support for J784S4 SoC") Signed-off-by: Thejasvi Konduru <t-konduru@ti.com> Reviewed-by: Nishanth Menon <nm@ti.com> Link: https://lore.kernel.org/r/20230503083143.32369-1-t-konduru@ti.com Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com>
