2017-07-11tegra: fdt: Ensure that the console UART is enabledSimon Glass
Many tegra boards have the console UART node disabled. With livetree this prevents serial from working since it does not 'force' the console to be bound. Updates the affected boards to fix this error. The boards were checked with: for b in $(grep tegra boards.cfg |grep -v integrator | \ awk '{print $7}' | sort); do echo $b; fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay; done Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Tested-on: Beaver, Jetson-TK1
2016-09-27ARM: tegra: fix USB controller aliasesStephen Warren
Some boards have a different set of USB controllers enabled in DT than the set referenced by /alias entries. This patch fixes that. For example, this avoids the following message while booting on Ventana, which is caused by the fact that the USB0 controller had no alias, and defaulted to wanting a sequence number of 0, which was later explicitly requested by the alias for USB controller 2. USB2: Device 'usb@c5008000': seq 0 is in use by 'usb@c5000000' This didn't affect USB operation in any way though. Related, there's no need for the USB controller aliases to have an order that's different from the HW order, so re-order any aliases to match the HW ordering. This has the benefit that since USB controller 0 is the only one that supports device-mode in HW, and U-Boot only supports enabling device move on controller 0, there's now good synergy in the ordering! For Tegra20, that's not relevant at present since USB device mode doesn't work correctly on that SoC, but it will save some head-scratching later. This patch doesn't fix the colibri_t20 board, even though it has the same issue, since Marcel already sent a patch for that.

2016-09-27ARM: tegra: fix USB ULPI PHY reset signal inversion confusionStephen Warren
USB ULPI PHY reset signals are typically active low. Consequently, they should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use. However, in DT properties that U-Boot does use, the value has been set to 0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot. This change fixes the DT to correctly represent the HW, and fixes the Tegra USB driver to cope with the fact that dm_gpio_set_value() internally handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

2016-09-27mmc: tegra: use correct alias for SDHCI/MMC nodesStephen Warren
The Tegra MMC driver currently honors "sdhci" entries in /aliases. The MMC core however uses "mmc" entries in /aliases. This difference will be relevant once the Tegra MMC driver is converted to DM, and the MMC core handles alias lookups. To avoid issues during that conversion, fix the Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC core does.

2016-07-05video: tegra: Move to using simple-panel and pwm-backlightSimon Glass
We have standard drivers for panels and backlights which can do most of the work for us. Move the tegra20 LCD driver over to use those instead of custom code. This patch includes device tree changes for the nvidia boards. I have only been able to test seaboard. If this patch is applied, these boards will also need to be synced with the kernel, and updated to use display-timings: - colibri - medcom-wide - paz00 - tec Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

2016-02-16tegra: dts: Sync tegra20.dtsi with Linux v4.4Simon Glass
This file has changed quite a bit since it was set up. Sync it back with Linux v4.4. Adjust the users slightly to cope with the changes: - the host1x node is now called host1x@50000000 - we need a clocks node to provide the clk32k_in phandle - active usb nodes need status = "okay" - active i2c nodes need status = "okay" Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

2014-09-10tegra: dts: Add serial port detailsSimon Glass
Some Tegra device tree files do not include information about the serial ports. Add this and also add information about the input clock speed. The console alias needs to be set up to indicate which port is used for the console. Also add a binding file since this is missing.

2014-02-19dts: move device tree sources to arch/$(ARCH)/dts/Masahiro Yamada
Unlike Linux Kernel, U-Boot historically had *.dts files under board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/. I think arch/$(ARCH)/dts dicretory is a better location to store both *.dts and *.dtsi files. For example, before this commit, board/xilinx/dts directory had both Microblaze dts (microblaze-generic.dts) and ARM dts (zynq-*.dts), which are totally unrelated. This commit moves *.dts to arch/$(ARCH)/dts/ directories, allowing us to describe nicely mutiple DTBs generation in the next commit. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
