2023-07-20pinctrl: Explicitly include correct DT includesRob Herring1-1/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2020-07-07pinctrl: meson: fix drive strength register and bit calculationHyeonki Hong1-4/+7
If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two or more registers. However, when register and bit were calculated, the first register defined in the bank was used, and the bit was calculated based on the first pin. This causes problems in setting the driving strength. The following method was used to solve this problem: A bit is calculated first using predefined strides. Then, If the bit is 32 or more, the register is changed by the quotient of the bit divided by 32. And the bit is set to the remainder.

2020-01-07pinctrl: meson: Fix wrong shift value when get drive-strengthQianggui Song1-0/+1
In meson_pinconf_get_drive_strength, variable bit is calculated by meson_calc_reg_and_bit, this value is the offset from the first pin of a certain bank to current pin, while Meson SoCs use two bits for each pin to depict drive-strength. So a left shift by 1 should be done or node pinconf-pins shows wrong message.

2019-11-19pinctrl: meson: add pinctrl driver support for Meson-A1 SoCQianggui Song5-0/+960
Meson A1 SoC share the same register layout of pinmux with previous Meson-G12A, however there is difference for gpio and pin config register in A1. The main difference is that registers before A1 are grouped by function while those of A1 are by bank. The new register layout is as below: /* first bank */ /* addr */ - P_PADCTRL_GPIOP_I base + 0x00 << 2 - P_PADCTRL_GPIOP_O base + 0x01 << 2 - P_PADCTRL_GPIOP_OEN base + 0x02 << 2 - P_PADCTRL_GPIOP_PULL_EN base + 0x03 << 2 - P_PADCTRL_GPIOP_PULL_UP base + 0x04 << 2 - P_PADCTRL_GPIOP_DS base + 0x05 << 2 /* second bank */ - P_PADCTRL_GPIOB_I base + 0x10 << 2 - P_PADCTRL_GPIOB_O base + 0x11 << 2 - P_PADCTRL_GPIOB_OEN base + 0x12 << 2 - P_PADCTRL_GPIOB_PULL_EN base + 0x13 << 2 - P_PADCTRL_GPIOB_PULL_UP base + 0x14 << 2 - P_PADCTRL_GPIOB_DS base + 0x15 << 2 Each bank contains at least 6 registers to be configured, if one bank has more than 16 gpios, an extra P_PADCTRL_GPIO[X]_DS_EXT is included. Between two adjacent P_PADCTRL_GPIO[X]_I, there is an offset 0x10, that is to say, for third bank, the offsets will be 0x20,0x21,0x22,0x23,0x24 ,0x25 according to above register layout. For previous chips, registers are grouped according to their functions while registers of A1 are according to bank.Also note that there is no AO bank any more in A1. Current Meson pinctrl driver can cover such change by using base address of GPIO as that of drive-strength. While simply giving reg_ds = reg_pullen make wrong value to reg_ds for Socs that do not support drive-strength like AXG.To make things simple, add an extra dt parser function for a1 and remain the old dt parser function for only reg parsing.

2019-11-19pinctrl: meson: add a new callback for SoCs fixupQianggui Song8-9/+39
In meson_pinctrl_parse_dt, it contains two parts: reg parsing and SoC relative fixup for AO. Several fixups in the same code make it hard to maintain, so move all fixups to each SoC's callback and make meson_pinctrl_parse_dt just do the reg parsing, separate these two parts.Overview of all current Meson SoCs fixup is as below: +------+--------------------------------------+--------------------------+ | | | | | SoC | EE domain | AO domain | +------+--------------------------------------+--------------------------+ |m8 | parse regs: | parse regs: | |m8b | gpio,mux,pull,pull-enable(skip ds) | gpio,mux,pull(skip ds)| |gxl | fixup: | fixup: | |gxbb | no | pull-enable = pull; | |axg | | | +------+--------------------------------------+--------------------------+ |g12a | parse regs: | parse regs: | |sm1 | gpio,mux,pull,pull-enable,ds | gpio,mux,ds | | | fixup: | fixup: | | | no | pull = gpio; | | | | pull-enable = gpio; | +------+--------------------------------------+--------------------------+ |a1 or | parse regs: | |later | gpio/mux (without ao domain) | |SoCs | fixup: | | | pull = gpio; pull-enable = gpio; ds = gpio; | +------+-----------------------------------------------------------------+ Since m8-axg share the same ao fixup, make a common function meson8_aobus_parse_dt_extra to do the job.

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 ...

Since Meson G12A SoC, Introduce new ao registers AO_RTI_PULL_UP_EN_REG and AO_GPIO_O. These bits of controlling output level are remapped to the new register AO_GPIO_O, and the AO_GPIO_O_EN_N support only controlling output enable. These bits of controlling pull enable are remapped to the new register AO_RTI_PULL_UP_EN_REG, and the AO_RTI_PULL_UP_REG support only controlling pull type(up/down). The new layout of ao gpio/pull registers is as follows: - AO_GPIO_O_EN_N [offset: 0x9 << 2] - AO_GPIO_I [offset: 0xa << 2] - AO_RTI_PULL_UP_REG [offset: 0xb << 2] - AO_RTI_PULL_UP_EN_REG [offset: 0xc << 2] - AO_GPIO_O [offset: 0xd << 2] From above, we can see ao GPIO registers region has been separated by the ao pull registers. In order to ensure the continuity of the region on software, the ao GPIO and ao pull registers use the same base address, but can be identified by the offset.
