2019-07-13Merge tag 'pinctrl-v5.3-1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...
2019-06-26pinctrl: madera: Fixup SPDX headersCharles Keepax
GPL-2.0-only is the preferred way of expressing v2 of the GPL, so switch to that. Remove some redundant copyright notices and correct some instances where the wrong comment type has been used in header files.

2019-04-04pinctrl: lochnagar: Add support for the Cirrus Logic LochnagarCharles Keepax
Lochnagar is an evaluation and development board for Cirrus Logic Smart CODEC and Amp devices. It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver supports the board controller chip on the Lochnagar board. Lochnagar provides many pins which can generally be used for an audio function such as an AIF or a PDM interface, but also as GPIOs.

2019-01-28pinctrl: remove pinctrl/machine.h inclusion from pinctrl/pinconf.hVladimir Zapolskiy
The change adds explicit inclusion of linux/pinctrl/machine.h header to the only needed pinctrl-madera-core.c file, and therefore inclusion of pinctrl/machine.h header from pinctrl/pinconf.h can be removed. The change is preparatory to a follow-up reversal of commit f07512e615dd ("pinctrl/pinconfig: add debug interface").

2018-10-12pinctrl: madera: Fix uninitialized variable bug in madera_mux_set_muxGustavo A. R. Silva
There is a potential execution path in which variable *ret* is checked in an IF statement, and then its value is used to report an error at line 659 without being properly initialized previously: 659 if (ret) 660 dev_err(priv->dev, "Failed to write to 0x%x (%d)\n", reg, ret); Fix this by initializing variable *ret* to 0 in order to avoid unpredictable or unintended results.

2018-06-05pinctrl: madera: Add driver for Cirrus Logic Madera codecsRichard Fitzgerald
These codecs have a variable number of I/O lines each of which is individually selectable to a wide range of possible functions. The functionality is slightly different from the traditional muxed GPIO since most of the functions can be mapped to any pin (and even the same function to multiple pins). Most pins have a dedicated "alternate" function that is only available on that pin. The alternate functions are usually a group of signals, though it is not always necessary to enable the full group, depending on the alternate function and how it is to be used. The mapping between alternate functions and GPIO pins varies between codecs depending on the number of alternate functions and available pins.
