2019-10-02ARM: dts: exynos: Add support ARM architected timers on Exynos5Marek Szyprowski
All CortexA7/A15 based Exynos5 SoCs have ARM architected timers, so enable support for them directly in the base dtsi. None of the known firmware properly configures CNTFRQ arch timer register, so force clock frequency to 24MHz, which is the only configuration supported by the remaining clock drivers so far. Stock firmware for Peach Pit and Pi Chromebooks also doesn't reset properly other arch timer registers, so add respective properties indicating that. Other Exynos5-based boards behaves correctly in this area, what finally allows to enable support for KVM-based virtualization.

2019-09-02ARM: dts: exynos: Mark LDO10 as always-on on Peach Pit/Pi ChromebooksMarek Szyprowski
Commit aff138bf8e37 ("ARM: dts: exynos: Add TMU nodes regulator supply for Peach boards") assigned LDO10 to Exynos Thermal Measurement Unit, but it turned out that it supplies also some other critical parts and board freezes/crashes when it is turned off. The mentioned commit made Exynos TMU a consumer of that regulator and in typical case Exynos TMU driver keeps it enabled from early boot. However there are such configurations (example is multi_v7_defconfig), in which some of the regulators are compiled as modules and are not available from early boot. In such case it may happen that LDO10 is turned off by regulator core, because it has no consumers yet (in this case consumer drivers cannot get it, because the supply regulators for it are not yet available). This in turn causes the board to crash. This patch restores 'always-on' property for the LDO10 regulator.

2018-08-30ARM: dts: exynos: Fix regulators configuration on Peach Pi/Pit ChromebooksMarek Szyprowski
Regulators, which are marked as 'on-in-suspend' seems to be critical for board operation, thus they must not be disabled anytime. This can be only assured by marking them as 'always-on', because otherwise some actions of their clients might result in turning them off. This patch restores suspend/resume operation on Peach-Pit Chromebook board. It partially reverts 'always-on' property removal done by the commit mentioned in the Fixes tag.

2017-05-15ARM: dts: exynos: Remove MFC reserved buffersMarek Szyprowski
During my research I found that some of the requirements for the memory buffers for MFC v6+ devices were blindly copied from the previous (v5) version and simply turned out to be excessive. The relaxed requirements are applied by the recent patches to the MFC driver and the driver is now fully functional even without the reserved memory blocks for all v6+ variants.

2016-08-24ARM: dts: exynos: Use 'hpd-gpios' instead of 'hpd-gpio'Milo Kim
This patch enables getting a HPD GPIO descriptor quicker. The exynos-hdmi driver uses "hpd" for HDMI hot plug detection. static int hdmi_resources_init(struct hdmi_context *hdata) { ... hdata->hpd_gpio = devm_gpiod_get(dev, "hpd", GPIOD_IN); ... } This calls 'of_find_gpio()' and it generates the GPIO consumer ID by referring GPIO suffix. So 'hpd-gpios' is preferred on getting a GPIO descriptor. However, if the device tree uses 'hpd-gpio', then the exynos-hdmi driver always retries to get a GPIO descriptor because the first GPIO suffix is not 'gpio' but 'gpios'. So you always see the debug message below. of_get_named_gpiod_flags: can't parse 'hpd-gpios' property of node '/soc/hdmi@14530000[0]' Use the preferred property, 'hpd-gpios' instead of 'hpd-gpio'.

The regulator always-on property should only be used for regulators that either can't be disabled or the drivers for the client devices are not enabling the regulator and so being disabled due to unused. There are some max77802 regulators in the Peach Pit and Pi boards that are always-on but shouldn't since they are enabled by drivers: BUCK5 is max77802 inl1 supply BUCK7 is max77802 inl{2,10} supply BUCK9 is max77802 inl{3,4,5,7} supply BUCK10 is mmc1 vqmmc supply LDO9 is adc vdd supply This patch removes the always-on property for these regulators. Some regulators should remain always-on even when they are used as input supplies, because these regulators are also used by other components that are not described in the DT, for example: LDO10 is hdmi vdd_osc supply but it's also used as input supply for the Exynos5420 temperature sensor. LDO8 is hdmi vdd and vdd_pll supply but it's also used as supply for the Exynos5420 Display port. BUCK2 and BUCK6 are the vdd supplies for the EAGLE and KFC clusters.

2016-01-28ARM: dts: Make CPU configuration more readable on exynos542x/5800Krzysztof Kozlowski
Exynos5420 and Exynos5800 boards boot from big core (A15) but Exynos5422 boards choose otherwise: LITTLE core (A7) (on Exynos5422 this is property of the board - configurable by pulling up/down gpg2-1). To make user-visible CPU ordering more consistent the 'cpus' node was overridden by exynos5422-cpus.dtsi. However this is a little bit ugly and error-prone. Overriding the CPU child nodes requires to basically reverse what was done initially in exynos5420.dtsi. Instead, split CPU configuration entirely to separate files which should be included by board DTS.

2015-02-27ARM: dts: Mux XMMCnDATA[0] pad correctly for Exynos5420 boardsJavier Martinez Canillas
The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3 MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a GPIO or external interrupt to allow the MMC controller to communicate with the attached cards or SDIO devices. Which data lines needs to be muxed as SD_n_DATA depends on the bus width used for data transfer: * bus-width = <1> needs SD_n_DATA[0] * bus-width = <4> needs SD_n_DATA[0-3] * bus-width = <8> needs SD_n_DATA[0-7] The Exynos5250-pinctrl.dtsi file that defines the groups of pins has SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them needs to be included in the device node's pinctrl property. But Exynos5420-pinctrl has a different definition and only includes SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1 and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads. It seems all Exynos5420 boards had just cargo cult the pinctrl lines assuming that sdn_bus4 also included SD_n_DATA[0] and it only works because the bootloader muxes the pads correctly. But that is not the case for the devices not used by the bootloader such as WiFi modules. Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.
