2019-08-12pinctrl: sh-pfc: Remove incomplete flag "cfg->type"Yoshihiro Shimoda1-26/+0
The old commit c58d9c1b26e3 ("sh-pfc: Implement generic pinconf support") broke the cfg->type flag to PINMUX_TYPE_FUNCTION because sh_pfc_pinconf_set() didn't call sh_pfc_reconfig_pin(). Now if we fix the cfg->type condition, it gets worse because: - Some drivers might be deferred so that .set_mux() will be called multiple times. - In such the case, the sh-pfc driver returns -EBUSY even if the group is the same, and then that driver fails to probe. Since the pinctrl subsystem already has such conditions according to @set_mux and @gpio_request_enable, this patch just remove the incomplete flag from sh-pfc/pinctrl.c.

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 ...

2019-06-04pinctrl: sh-pfc: Add new non-GPIO helper macrosGeert Uytterhoeven1-0/+56
Add new macros for describing pins without GPIO functionality: - NOGP_ALL() expands to a list of PIN_id values, to be used for generating symbolic enum values, - PINMUX_NOGP_ALL() expands to a list of sh_pfc_pin entries, to list all pins and their capabilities. Both macros depend on an SoC-specific CPU_ALL_NOGP() macro, to be provided by each individual SoC pin control driver. The new macros offer two advantages over the existing SH_PFC_PIN_NAMED() and SH_PFC_PIN_NAMED_CFG() macros: 1. They do not rely on PIN_NUMBER() macros and physical pin numbering, hence do not suffer from pin numbering confusion among different SoC/SiP packages. 2. They are similar in spirit to the existing scheme for handling pins with GPIO functionality. Note that internal to the driver, non-GPIO pins use a sequential numbering scheme which starts after the highest GPIO pin number in use. This value is calculated automatically, using two new helper macros, for systems with either 32-port bank (GP port style) or linear (PORT style) pin space. Sample expansion: GP_LAST = sizeof(union { char dummy[0] __attribute__((deprecated, deprecated)); char GP_0_0[(0 * 32) + 0] __attribute__((deprecated, deprecated)); char GP_0_1[(0 * 32) + 1] __attribute__((deprecated, deprecated)); ... char GP_7_3[(7 * 32) + 3] __attribute__((deprecated, deprecated)); }) Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
2019-06-01treewide: fix typos of SPDX-License-IdentifierMasahiro Yamada1-1/+1
Prior to the adoption of SPDX, it was difficult for tools to determine the correct license due to incomplete or badly formatted license text. The SPDX solves this issue, assuming people can correctly spell "SPDX-License-Identifier" although this assumption is broken in some places. Since scripts/spdxcheck.py parses only lines that exactly matches to the correct tag, it cannot (should not) detect this kind of error. If the correct tag is missing, scripts/checkpatch.pl warns like this: WARNING: Missing or malformed SPDX-License-Identifier tag in line * So, people should notice it before the patch submission, but in reality broken tags sometimes slip in. The checkpatch warning is not useful for checking the committed files globally since large number of files still have no SPDX tag. Also, I am not sure about the legal effect when the SPDX tag is broken. Anyway, these typos are absolutely worth fixing. It is pretty easy to find suspicious lines by grep. $ git grep --not -e SPDX-License-Identifier --and -e SPDX- -- \ :^LICENSES :^scripts/spdxcheck.py :^*/license-rules.rst arch/arm/kernel/bugs.c:// SPDX-Identifier: GPL-2.0 drivers/phy/st/phy-stm32-usbphyc.c:// SPDX-Licence-Identifier: GPL-2.0 drivers/pinctrl/sh-pfc/pfc-r8a77980.c:// SPDX-Lincense-Identifier: GPL 2.0 lib/test_stackinit.c:// SPDX-Licenses: GPLv2 sound/soc/codecs/max9759.c:// SPDX-Licence-Identifier: GPL-2.0 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The pinmux groups and functions arrays may contain two parts, to ease supporting SoCs that expose pin subsets of other related SoCs. Both parts need to be declared with explicit sizes, which thus need to be updated when adding support for more groups and functions. If a size is too small, the compiler will detect this at build time ("excess elements in array initializer"). If a size is too large, this may go undetected (for pin groups), lead to pin controller registration failures (for pin functions: "pinmux ops has no name for functionN"), or crash the optional run-time debug code (for pin groups).

2019-04-02pinctrl: sh-pfc: rcar-gen3: Remove HDMI CEC pins, groups, and functionsTakeshi Kihara4-97/+26
The HDMI CEC function is not supported by the R-Car Gen3 Hardware Manual Rev 1.00. Therefore, delete the corresponding pin groups and functions, and rename the HDMI[01]_CEC definitions to match their GPIO functionality.

2019-04-02pinctrl: sh-pfc: Validate enum IDs for regs with variable-width fieldsGeert Uytterhoeven2-0/+13
Add a run-time check to the PINMUX_CFG_REG_VAR() macro, to ensure the number of provided enum IDs is correct. This cannot be done at build time, as the number of values depends on the variable-width fields in the config register. This helps catching bugs early.

2019-04-02pinctrl: sh-pfc: Absorb enum IDs in PINMUX_DATA_REG() macroGeert Uytterhoeven16-420/+420
Currently the PINMUX_DATA_REG() macro must be followed by initialization data, specifying all enum IDs. Hence the macro itself does not know anything about the enum IDs, preventing the macro from performing any validation on it. Make the macro accept the enum IDs as a parameter, and update all users. Note that array data enclosed by curly braces cannot be passed to a macro as a parameter, hence the enum IDs are wrapped using the GROUP() macro. No functional changes.
