2019-04-15dt-bindings: mmc: tegra: document Tegra194 compatible stringSowjanya Komatineni
SDHCI controller of Tegra194 is similar to SDHCI controller in Tegra186. This patch documents Tegra194 sdhci compatible string. Signed-off-by: Sowjanya Komatineni <skomatineni@nvidia.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2019-02-25dt-bindings: mmc: tegra: Add pinctrl for SDMMC drive strengthsSowjanya Komatineni
Add pinctrls for 3V3 and 1V8 pad drive strength configuration for Tegra210 sdmmc. Tegra210 sdmmc has pad configuration registers in pinmux register domain and handled thru pinctrl to pinmux device node. Tegra186 and Tegra194 has pad configuration register with in the SDMMC register domain itself and are handles thru drive strength properties in sdmmc device node.

2017-04-24dt-bindings: mmc: tegra: Reformat compatible string listThierry Reding
The list of compatible strings is somewhat difficult to read and extend. Reformat it into a list to make it more easily extensible. While at it, also remove the "plus one of the above" clause because it isn't actually valid. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2015-02-03Documentation: DT bindings: add more Tegra chip compatible stringsPaul Walmsley
Align compatible strings for several IP blocks present on Tegra chips with the latest doctrine from the DT maintainers: http://marc.info/?l=devicetree&m=142255654213019&w=2 The primary objective here is to avoid checkpatch warnings, per: http://marc.info/?l=linux-tegra&m=142201349727836&w=2 DT binding text files have been updated for the following IP blocks: - PCIe - SOR - SoC timers - AHB "gizmo" - APB_MISC - pinmux control - UART - PWM - I2C - SPI - RTC - PMC - eFuse - AHCI - HDA - XUSB_PADCTRL - SDHCI - SOC_THERM - AHUB - I2S - EHCI - USB PHY N.B. The nvidia,tegra20-timer compatible string is removed from the nvidia,tegra30-timer.txt documentation file because it's already mentioned in the nvidia,tegra20-timer.txt documentation file. This second version takes into account the following requests from Rob Herring <robherring2@gmail.com>: - Per-IP block patches have been combined into a single patch - Explicit documentation about which compatible strings are actually matched by the driver has been removed. In its place is implicit documentation that loosely follows Rob's prescribed format: "Must contain '"nvidia,<chip>-pcie", "nvidia,tegra20-pcie"' where <chip> is tegra30, tegra132, ..."

2013-12-11ARM: tegra: document reset properties in DT bindingsStephen Warren
Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

2013-12-11ARM: tegra: add missing clock documentation to DT bindingsStephen Warren
Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties.

2012-06-11dt: name all Tegra binding docs consistentlyStephen Warren
Rename all Tegra binding documentation according to the first or primary compatible value they describe. This provides a clear naming scheme for the files, and prevents any naming conflicts should future SoC versions require their own binding. Signed-off-by: Stephen Warren <swarren@nvidia.com>
