2022-05-04ARM: dts: exynos: drop useless 'dma-channels/requests' propertiesKrzysztof Kozlowski1-10/+0
The pl330 DMA controller provides number of DMA channels and requests through its registers, so duplicating this information (with a chance of mistakes) in DTS is pointless. Additionally the DTS used always wrong property names which causes DT schema check failures - the bindings documented 'dma-channels' and 'dma-requests' properties without leading hash sign.

Fix up inconsistent usage of upper and lowercase letters in "Samsung" and "Exynos" names. "SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked names. Therefore they should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

2017-03-07ARM: dts: exynos: Do not ignore real-world fuse values for thermal zone 0 on ↵Krzysztof Kozlowski1-5/+5
Exynos5420 In Odroid XU3 Lite board, the temperature levels reported for thermal zone 0 were weird. In warm room: /sys/class/thermal/thermal_zone0/temp:32000 /sys/class/thermal/thermal_zone1/temp:51000 /sys/class/thermal/thermal_zone2/temp:55000 /sys/class/thermal/thermal_zone3/temp:54000 /sys/class/thermal/thermal_zone4/temp:51000 Sometimes after booting the value was even equal to ambient temperature which is highly unlikely to be a real temperature of sensor in SoC. The thermal sensor's calibration (trimming) is based on fused values. In case of the board above, the fused values are: 35, 52, 43, 58 and 43 (corresponding to each TMU device). However driver defined a minimum value for fused data as 40 and for smaller values it was using a hard-coded 55 instead. This lead to mapping data from sensor to wrong temperatures for thermal zone 0. Various vendor 3.10 trees (Hardkernel's based on Samsung LSI, Artik 10) do not impose any limits on fused values. Since we do not have any knowledge about these limits, use 0 as a minimum accepted fused value. This should essentially allow accepting any reasonable fused value thus behaving like vendor driver. The exynos5420-tmu-sensor-conf.dtsi is copied directly from existing exynos4412 with one change - the samsung,tmu_min_efuse_value.

2016-11-03ARM: dts: exynos: Fix invalid GIC interrupt flags in exynos5410/exynos542xKrzysztof Kozlowski1-39/+39
Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and generates an error: genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68) The GIC requires shared interrupts to be edge rising or level high. Platform declares support for both. Arbitrarily choose level high everywhere hoping it will work on each platform.

git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into next/dt Topic branch for adding Exynos 5410 Odroid XU board for v4.8. This brings support for Hardkernel's Odroid XU board. It was the first design with big.LITTLE SoC from Samsung: Exynos5410. The board is not very popular. Newer XU3 and XU4 got more attention. Board details: 1. Exynos5410 octa-core (A15+A7, however as of now only one cluster is enabled), 2. 2 GB DDR3 RAM, 3. PowerVR SGX544MP3 GPU (not enabled in DTS), 4. USB 3.0 Host x 1, USB 3.0 OTG x 1, USB 2.0 Host x 4, 5. HDMI 1.4a, MIPI DSI and Display Port (Display Port not on all of revisions though), 6. eMMC 4.5 and microSD slots. * tag 'samsung-dt-odroid-xu-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (28 commits) ARM: dts: exynos: Add watchdog and Security SubSystem to Exynos5410 ARM: dts: exynos: Configure PWM, usb3503, PMIC and thermal on Odroid XU board ARM: dts: exynos: Add Thermal Management Unit to Exynos5410 ARM: dts: exynos: Interrupt for USB DWC3-1 differs between Exynos5420 and 5410 dt-bindings: clock: Add watchdog and SSS clock IDs to Exynos5410 dt-bindings: clock: Add TMU clock ID to Exynos5410 ARM: dts: exynos: Add RTC and I2C to Exynos5410 ARM: dts: exynos: Add I2C, PWM and UART pinctrl to Exynos5410 ARM: dts: exynos: Move HSI2C nodes to exynos54xx.dtsi ARM: dts: exynos: Add initial support for Odroid XU board ARM: dts: exynos: Add USB to Exynos5410 ARM: dts: exynos: Move common Exynos5410/542x/5800 nodes to new DTSI ARM: dts: exynos: MCT is not an interrupt controller and extend length of iomap ARM: dts: exynos: Enable UART3 on Exynos5410 ARM: dts: exynos: Include common exynos5 in exynos5410.dtsi ARM: dts: exynos: Move Exynos5250 and Exynos5420 nodes under soc ARM: dts: exynos: Use phandle to get parent node in exynos5250-snow ARM: dts: exynos: Prepare for inclusion of exynos5.dtsi in exynos5410.dtsi ARM: dts: exynos: Move common nodes to exynos5.dtsi ARM: dts: exynos: Split Odroid XU3 LEDs to separate DTSI ...
