* ARM: dts: ux500: Add trips to battery thermal zonesLinus Walleij2022-11-011-0/+8
| | | | | | | | | | | | | | | | | | | Recent changes to the thermal framework has made the trip points (trips) for thermal zones compulsory, which made the Ux500 DTS files break validation and also stopped probing because of similar changes to the code. Fix this by adding an "outer bounding box": battery thermal zones should not get warmer than 70 degress, then we will shut down.

* ARM: dts: ux500: Update AB850[05] nodesLinus Walleij2022-02-111-4/+4
| | | | | | | | | | | | | | The new YAML device tree bindings gives new and proper names to several of the AB850[05] nodes and redefines the way we use numbering on PWMs to use reg. Update all the DTS nodes accordingly. Add the missing thermal node to the AB8505. Drop the debugfs nodes because these are not real devices. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* ARM: dts: ux500: Switch battery nodes to standardLinus Walleij2021-10-141-0/+6
| | | | | | | | | | | | | | | | | | | | This force-converts the per-device battery node into the standard properties using "simple-battery" for the HREF machines and the corresponding Samsung battery for the mobile phones. This is fine to do since the battery data in the DTS files has never been deployed or used. In commit a1149ae97554 "ARM: ux500: Disable Power Supply and Battery Management by default" it was turned off and has not been switched back on since. In the meantime standardized bindings for batteries have appeared making the old AB8500 battery bindings obsolete. The battery node which is now in the middle of an included file is obviously a per-device piece of information so push this down to each board. The HREF machines all have the same battery and can share a single node in the HREF dtsi file. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* | ARM: dts: ux500: Reserve memory carveoutsLinus Walleij2021-01-151-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ux500 platforms have some memory carveouts set aside for communicating with the modem and for the initial secure software (ISSW). These areas are protected by the memory controller and will result in an external abort if accessed like common read/write memory. On the legacy boot loaders, these were set aside by using cmdline arguments such as this: mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M mem=638M@385M Reserve the relevant areas in the device tree instead. The "mali", "hwmem", "mem_ram_console" and the trailing 1MB at the end of the memory reservations in the list are not relevant for the upstream kernel as these are nowadays replaced with upstream technologies such as CMA. The modem and ISSW reservations are necessary. This was manifested in a bug that surfaced in response to commit 7fef431be9c9 ("mm/page_alloc: place pages to tail in __free_pages_core()") which changes the behaviour of memory allocations in such a way that the platform will sooner run into these dangerous areas, with "Unhandled fault: imprecise external abort (0xc06) at 0xb6fd83dc" or similar: the real reason turns out to be that the PTE is pointing right into one of the reserved memory areas. We were just lucky until now. We need to augment the DB8500 and DB8520 SoCs similarly and also create a new include for the DB9500 used in the Snowball since this does not have a modem and thus does not need the modem memory reservation, albeit it needs the ISSW reservation.

* ARM: dts: ux500: Disable I2C/SPI buses by defaultStephan Gerhold2019-12-091-0/+5
| | | | | | | | | | | | | | | | | | | At the moment, all 5 I2C and 6 SPI buses are probed and exposed to user-space by default - even if they are not muxed to any pins on the board. This means that user-space sees an I2C/SPI bus that cannot be actually used properly. In some cases this was used to put the corresponding pins into a low power sleep mode - but even then the pins first need to be configured by the board-specific device tree part. Avoid exposing unconfigured devices to user-space by disabling the I2C/SPI buses by default. Enable them in the board device trees when needed.

| | | | | | | | | | | | | | | | Some components (e.g. SDI, I2C) can be used with different pin assignments. Before we can add the alternative configurations, we need to rename the current configurations to more generic names. Each pin configuration usually configures one specific pin group. Therefore we rename the configurations to use the pin group as name. Make up for the slightly longer names by removing the "_mode" suffix. Rename all existing uses to use the new labels.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a very annoying regression on the Snowball SD card that has been around for a while. It turns out that the device tree does not configure the direction pins properly, nor sets up the pins for the voltage converter properly at boot. Unless all things are correctly set up, the feedback clock will not work, and makes the driver spew messages in the console (but it works, very slowly): root@Ux500:/ mount /dev/mmcblk0p2 /mnt/ [ 9.953460] mmci-pl18x 80126000.sdi0_per1: error during DMA transfer!

Add in the SDR12 and SDR25 modes which this host can do without any problems. I don't know if this has ever been correct, sadly. It works after this patch.

* ARM: ux500: fix MMC/SD card regressionLinus Walleij2015-07-141-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Ux500 is regressing due to commit a21763a0b1e5a5ab8310f581886d04beadc16616 "pinctrl: nomadik: activate strict mux mode" which disallows Nomadik GPIO 5 to be muxed in as a level shifter voltage select pin, as it is currently described as being used for RX on UART1. The behaviour is correct, instead the hardware config has been incorrecly specified: UART1 is indeed unused on HREFv60plus and Snowball and that is why HREFv60plus can use the pins it would normally occupy as the voltage select line for the MMC/SD levelshifter (Snowball uses it for I2C4). The reason UART1 was anyway enabled on these platforms was probably to secure the port enumeration to userspace. This can be solved by using aliases (done in a separate patch) so we can now deactivate UART1 and let MMC/SD use it properly on HREFv60plus. We explicitly activate it only for the older HREFprev60 board. To complete, we set up the pin configuration for these pins properly in the sdi0 node.

| | | | | | | | | | | | | | | | | | | | The ST sensors on the Ux500 boards were not utilizing the IRQs for data ready sample triggers. Enable this by assigning the right GPIO lines and interrupt lines (when the GPIO lines are used for IRQs) to the accelerometer, gyro and magnetometer sensors.

| | | | | | | | | | | | | | | | | | The magnetometer found on the Ux500 TVK and Snowball boards is a LSM303DLH not a LSM303DLM, small differences but still different. Put in the right compatible strings and things start working smoothly. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

|/ | | | | | | | | | | The GPIO regulator for the SD-card isn't a ux500 SOC configuration, but instead it's specific to the board. Move the definition of it, into the board DTSs.

| | | | | | | | | This converts the Nomadik pin controller and all associated device trees to use the standard, generic config bindings for pin controllers.

| | | | | | | | | | | | | | | | | Analogous to commit 8858d88a25142544843869f0cd3e6654aa7b4aec that fixed commit 70b41abc151f9 "ARM: ux500: move MSP pin control to the device tree" accidentally activated MSP2, giving rise to a boot scroll scream as the kernel attempts to probe a driver for it and fails to obtain DMA channel 14. For some reason I forgot to fix this on the Snowball. Fix this up by marking the node disabled again.

| | | | | | | | | | The SPI0 block is not at all connected to the AB8500 on the Snowball: it is connected to the external header. These pins on the header may also be used for GPIO, but let's assume that SPI is a probable usecase on the Snowball and mux in the SPI block and use these for SPI.

| | | | | | | | | | | | | | This moves the MCDE pin control table out of the board file and into the device tree. Some pins and configs have been marked as used by sub-devices or slaves to the MCDE, such as I2C device 0-070 which is the HDMI interface circuit AV8100, but the pins rather belong to the MCDE SOC block as they come out of the main ASIC. The touch screen GPIO is not related to MCDE so this gets deleted and need to be tied to the respective touch screen (I2C) device once that device is added instead.
