Commit 4c9a27a6c66d ("ARM: tegra: Fix ULPI regression on Tegra20") changed "ulpi-link" clock from CDEV2 to PLL_P_OUT4. Turned out that PLL_P_OUT4 is the parent of CDEV2 clock and original clock setup of "ulpi-link" was correct. The reverted patch was fixing USB for one board and broke the other, now Tegra's clk driver correctly sets parent for the CDEV2 clock and hence patch could be reverted safely, restoring USB for all of the boards.

2018-03-08ARM: tegra: Fix ULPI regression on Tegra20Marcel Ziswiler
Since commit f8f8f1d04494 ("clk: Don't touch hardware when reparenting during registration") ULPI has been broken on Tegra20 leading to the following error message during boot: [ 1.974698] ulpi_phy_power_on: ulpi write failed [ 1.979384] tegra-ehci c5004000.usb: Failed to power on the phy [ 1.985434] tegra-ehci: probe of c5004000.usb failed with error -110 Debugging through the changes and finally also consulting the TRM revealed that rather than the CDEV2 clock off OSC requiring such pin muxing actually the PLL_P_OUT4 clock is in use. It looks like so far it just worked by chance of that one having been enabled which Stephen's commit now changed when reparenting sclk away from pll_p_out4 leaving that one disabled. Fix this by properly assigning the PLL_P_OUT4 clock as the ULPI PHY clock.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2016-04-12ARM: tegra: Correct interrupt type for ARM TWDJon Hunter
The ARM TWD interrupt is a private peripheral interrupt (PPI) and per the ARM GIC documentation, whether the type for PPIs can be set is IMPLEMENTATION DEFINED. For Tegra20/30 devices the PPI type cannot be set and so when we attempt to set the type for the ARM TWD interrupt it fails. This has gone unnoticed because it fails silently and because we cannot re-configure the type it has had no impact. Nevertheless fix the type for the TWD interrupt so that it matches the hardware configuration. Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

2015-10-15ARM: tegra: Comment out gpio-ranges propertiesThierry Reding
While the addition of these properties is technically correct it unveils a bug with deferred probe. The problem is that the presence of the gpio- range property causes the gpio-tegra driver to defer probe (it needs the pinctrl driver to be ready). That's technically correct, but it causes a couple of issues: - The keyboard on Chromebooks stops working. The reason for that is that the gpio-tegra device has not registered an IRQ domain by the time the EC SPI device is registered, hence the interrupt number resolves to 0. This is technically a bug in the SPI core, since it should really resolve the interrupt at probe time and defer if the IRQ domain isn't available yet. This is similar to what's done for I2C and platform device already. - The gpio-tegra device deferring probe means that it is moved to the end of the dpm_list. This list defines the suspend/resume order for devices. However the core lacks a way to move all users of the gpio-tegra device to the end of the dpm_list at the same time. This in turn results in a subtle bug on Jetson TK1, where the gpio-keys device is used to expose the power key as input. The power key is a convenient way to wake the system from suspend. Interestingly, the gpio-keys device ends up getting probed at a point after gpio-tegra has been probed successfully from having been deferred earlier. As such the driver doesn't need to defer the probe itself, and hence the device isn't moved to the end of the dpm_list. This causes the gpio-tegra device to be suspended before gpio-keys, which in turn leaves gpio-keys unable to wake the system from suspend. There are patches in the works to fix both of the above issues, but they are too involved to make it into v4.3, so in the meantime let's fix the regressions by commenting out the gpio-ranges properties until the fixes have landed.

2013-12-16ARM: tegra: add missing unit addresses to DTStephen Warren
DT node names should include a unit address iff the node has a reg property. For Tegra DTs at least, we were previously applying a different rule, namely that node names only needed to include a unit address if it was required to make the node name unique. Consequently, many unit addresses are missing. Add them. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-12-11ARM: tegra: remove legacy DMA entries from DTStephen Warren
Now that all Tegra drivers have been converted to use DMA APIs which retrieve DMA channel information from standard DMA DT properties, we can remove all the legacy DT DMA-related properties. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Thierry Reding <treding@nvidia.com>
2013-12-11ARM: tegra: remove legacy clock entries from DTStephen Warren
Now that all Tegra drivers have been converted to use the common reset framework, we can remove all the legacy DT clocks/clock-names entries for "clocks" that were only used with the old custom Tegra module reset API.

2013-12-11ARM: tegra: update DT files to add DMA propertiesStephen Warren
This patch switches the Tegra DT files to use the standard DMA DT bindings rather than custom properties. Note that the legacy properties are not yet removed; the drivers must be updated to use the new properties first.

2013-12-11ARM: tegra: update DT files to add reset propertiesStephen Warren
An earlier patch updated the Tegra DT bindings to require resets and reset-names properties to be filled in. This patch updates the DT files to include those properties. Note that any legacy clocks and clock-names entries that are replaced by reset properties are not yet removed; the drivers must be updated to use the new resets and reset-names properties first.

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.

2013-08-12ARM: dts: tegra: Increase prefetchable PCI memory spaceJay Agarwal
Instead of evenly splitting the 512 MiB area between prefetchable and non-prefetchable memory spaces, increase the prefetchable memory space to 384 MiB while at the same time decreasing the non-prefetchable memory space to 128 MiB. This is a more useful default as most PCIe devices require more prefetchable than non-prefetchable memory.
