2020-01-06dt-bindings: Rename Exynos to lowercaseKrzysztof Kozlowski
Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it 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.

2017-12-06dt-bindings: Remove leading 0x from bindings notationMathieu Malaterre
Improve the binding example by removing all the leading 0x to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" Converted using the following command: find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} + This is a follow up to commit 48c926cd3414 Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Rob Herring <robh@kernel.org>
2017-09-05dt-bindings: Remove "status" from examplesRob Herring
Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>
2014-03-14[media] Documentation: devicetree: Update Samsung FIMC DT bindingSylwester Nawrocki
This patch documents following updates of the Exynos4 SoC camera subsystem devicetree binding: - addition of #clock-cells and clock-output-names properties to 'camera' node - these are now needed so the image sensor sub-devices can reference clocks provided by the camera host interface, - dropped a note about required clock-frequency properties at the image sensor nodes; the sensor devices can now control their clock explicitly through the clk API and there is no need to require this property in the camera host interface binding.

2013-04-04[media] exynos4-is: Correct clock properties description at the DT binding ↵Sylwester Nawrocki
documentation The 'camera' DT node needs to have sclk_cam0/1 and pxl_async0/1 clocks specified, while 'fimc' nodes should have only "fimc" and "sclk_fimc". "mux" and "parent" are leftovers from early versions of patches adding DT support, when the IP bus clock parent clock was being set by the driver. A better solution is needed to have e.g. clocks driver setting all required parent clocks, before clock consumers start using the clocks. Currently this binding doesn't describe parent clocks setup, it needs to be specified and handled somewhere else.

2013-03-31[media] s5p-fimc: Use pinctrl API for camera ports configurationSylwester Nawrocki
Before the camera ports can be used the pinmux needs to be configured properly. This patch adds a function to set the camera ports pinctrl to a default state within the media driver's probe(). The camera port(s) are then configured for the video bus operation.

2013-03-31[media] s5p-fimc: Add device tree based sensors registrationSylwester Nawrocki
The sensor (I2C and/or SPI client) devices are instantiated by their corresponding control bus drivers. Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.

2013-03-31[media] s5p-fimc: Add device tree support for FIMC device driverSylwester Nawrocki
This patch adds device tree support for FIMC driver on S5PV210 and Exynos4 SoCs. The FIMC IP block's features and quirks encoded statically in the driver are now parsed from the device tree. Once all relevant platforms are converted to device tree based booting the FIMC variant data structures will all be removed from the driver.
