| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new SERDES driver for TI's AM654x SoC which configures the SERDES only for PCIe. Support fo USB3 will be added later. SERDES in am654x has three input clocks (left input, externel reference clock and right input) and two output clocks (left output and right output) in addition to a PLL mux clock which the SERDES uses for Clock Multiplier Unit (CMU refclock). The PLL mux clock can select from one of the three input clocks. The right output can select between left input and external reference clock while the left output can select between the right input and external reference clock. The driver has support to select PLL mux and left/right output mux as specified in device tree.

* | phy: phy-twl4030-usb: Fix cable state handlingTony Lindgren2019-04-171-22/+13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent regulator changes I noticed new warnings on doing rmmod of phy-twl4030-usb: WARNING: CPU: 0 PID: 1080 at drivers/regulator/core.c:2046 _regulator_put ... Turns out we can currently miss disconnect at least for cases where status is 0 and linkstat is 0. And in that case doing rmmod phy-twl4030-usb will produce the regulator_put() warning. This is because the missed disconnect causes unbalanced PM runtime calls and the regulators will be on exit. Let's fix the issue by using an atomic flag for the cable state to make sure that PM runtime won't get out of sync with the cable state. That way we can also simplify the code a bit. Note that we can also drop the old comments, those relate to issues that the battery charger driver and musb driver is dealing with rather than the USB PHY driver.

* phy: ti: introduce phy-gmii-sel driverGrygorii Strashko2018-12-123-0/+360
| | | | | | | | | | | | | | | | | | | | | | | TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports two 10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII interfaces. The interface mode is selected by configuring the MII mode selection register(s) (GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and bit fields placement in SCM are different between SoCs while fields meaning is the same. Historically CPSW external Port's interface mode selection configuration was introduced using custom API and driver cpsw-phy-sel.c. This leads to unnecessary driver, DT binding and custom API support effort. This patch introduces CPSW Port's PHY Interface Mode selection Driver (phy-gmii-sel) which implements standard Linux PHY interface and used as a replacement for TI's specific driver cpsw-phy-sel.c and corresponding custom API.

* phy: core: rework phy_set_mode to accept phy mode and submodeGrygorii Strashko2018-12-122-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the attempt to add support for Ethernet interface mode PHY (MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and duplicate there values from phy_interface_t enum (or introduce more PHY callbacks) [1]. Both approaches are ineffective and would lead to fast bloating of enum phy_mode or struct phy_ops in the process of adding more PHYs for different subsystems which will make them unmaintainable. As discussed in [1] the solution could be to introduce dual level PHYs mode configuration - PHY mode and PHY submode. The PHY mode will define generic PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem specific interface mode. The last is usually already defined in corresponding subsystem headers (phy_interface_t for Ethernet, enum usb_device_speed for USB). This patch is cumulative change which refactors PHY framework code to support dual level PHYs mode configuration - PHY mode and PHY submode. It extends .set_mode() callback to support additional parameter "int submode" and converts all corresponding PHY drivers to support new .set_mode() callback declaration. The new extended PHY API int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode) is introduced to support dual level PHYs mode configuration and existing phy_set_mode() API is converted to macros, so PHY framework consumers do not need to be changed (~21 matches).

| | | | | | | | | | | | | When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS, the counter will be incremented but the resume callback not called, so enumeration and charging will not start properly. To avoid that happen, disable irq on suspend and recheck on resume. Practically this happens when the device is woken up from suspend by plugging in usb.

| | | | | | | | | | | | | | | | | This converts from using a platform device for the CFGCHIP syscon regmap to using platform data to pass the regmap to consumers. A lazy getter function is used so that the regmap will only be created if it is actually used. This function will also be used in the clock init when we convert to the common clock framework. The USB PHY driver is currently the only consumer. This driver is updated to use platform data to get the CFGCHIP regmap instead of syscon_regmap_lookup_by_pdevname().

* | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
