Add initial pinctrl driver to support pin configuration for LPASS (Low Power Audio SubSystem) LPI (Low Power Island) pinctrl on SM8250. This IP is an additional pin control block for Audio Pins on top the existing SoC Top level pin-controller. Hardware setup looks like: TLMM GPIO[146 - 159] --> LPASS LPI GPIO [0 - 13] This pin controller has some similarities compared to Top level msm SoC Pin controller like 'each pin belongs to a single group' and so on. However this one is intended to control only audio pins in particular, which can not be configured/touched by the Top level SoC pin controller except setting them as gpios. Apart from this, slew rate is also available in this block for certain pins which are connected to SLIMbus or SoundWire Bus. Signed-off-by:

This patch is used to fix low level output voltage issue. A pin is changed from input pull-up to output high. The Dout value of the pin is default as 0. If we change the direction of the pin before the dout value of the pin, It maybe produce a low level output voltage between "input pull-up" and "output high". Signed-off-by:

Some products, like sama7g5, do not have a full last bank of PIO lines. In this case for example, sama7g5 only has 8 lines for the PE bank. PA0-31, PB0-31, PC0-31, PD0-31, PE0-7, in total 136 lines. To cope with this situation, added a data attribute that is product dependent, to specify the number of lines of the last bank. In case this number is different from the macro ATMEL_PIO_NPINS_PER_BANK, adjust the total number of lines accordingly. This will avoid advertising 160 lines instead of the actual 136, as this product supports, and to avoid reading/writing to invalid register addresses. Signed-off-by:

It is found on many allwinner soc that there is a low probability that the interrupt status cannot be read in sunxi_pinctrl_irq_handler. This will cause the interrupt status of a gpio bank to always be active on gic, preventing gic from responding to other spi interrupts correctly. So we should call the chained_irq_* each time enter sunxi_pinctrl_irq_handler(). Signed-off-by:

The interrupt descriptor cannot be found in the interrupt processing function, and this situation cannot happen when the system is running normally. It doesn't seem right to return directly to the status of not handling gic. In this case, it must be a bug, let's mark it with WARN_ON. Signed-off-by:

Baytrail pin control has a common register to set up debounce timeout. When a pin configuration requested debounce to be disabled, the rest of the pins may still want to have debounce enabled and thus rely on the common timeout value. Avoid clearing debounce value when turning it off for one pin while others may still use it.

On SuperH and ARM SH/R-Mobile SoCs, the pin control driver handles GPIOs, too. To reduce code size when compiling a kernel supporting only modern SoCs, most, but not all, of the GPIO functionality is protected by checks for CONFIG_PINCTRL_SH_FUNC_GPIO. Factor out the remaining parts when not needed: 1. sh_pfc_soc_info.{in,out}put describe GPIO pins that have input resp. output capabilities (SuperH and SH/R-Mobile). 2. sh_pfc_soc_info.gpio_irq{,_size} describe the mapping from GPIO pins to interrupt numbers (SH/R-Mobile). 3. sh_pfc_gpio_set_direction() configures GPIO direction, called from the GPIO driver through pinctrl_gpio_direction_{in,out}put() (SH/R-Mobile). Unfortunately this function cannot just be moved to drivers/pinctrl/renesas/gpio.c, as it relies on knowledge of sh_pfc_pinctrl, which is internal to drivers/pinctrl/renesas/pinctrl.c. While code size reduction is minimal, this does help in documenting depencies. Signed-off-by: -

Currently, the rcar_pinmux_[gs]et_bias() helpers handle only SoCs that have separate LSI Pin Pull-Enable (PUEN) and Pull-Up/Down Control (PUD) registers, like R-Car Gen3 and RZ/G2. Update the function to handle SoCs that have only LSI Pin Pull-Up Control Register (PUPR), like R-Car Gen1/Gen2 and RZ/G1. Reduce code duplication by converting the R-Car M1A pin control driver to use the common handler. Note that this changes behavior in case the (invalid!) option "bias-pull-down" is used in an R-Car M1A DTS: before, it was ignored silently; after this change, it is considered the same as "bias-pull-up".

The handling of the LSI Pin Pull-Up Control Registers (PUPR) on R-Car M1A uses register offsets instead of register physical addresses. This is different from the handling on other R-Car parts. Convert the bias handling from register offsets to physical addresses. This increases uniformity, and prepares for consolidation of the bias handling. Signed-off-by:

Shrink sh_pfc_pin_config from 8 to 2 bytes: - The mux_set flag can be removed, as a non-zero mark value means the same (zero = PINMUX_RESERVED is an invalid mark value), - The gpio_enabled flag needs only a single bit, - Mark values are small integers, and can easily fit in a 15-bit bitfield. This saves 6 bytes per pin when allocating the sh_pfc_pinctrl.configs array, i.e. it reduces run-time memory consumption by ca. 1.5 KiB. Signed-off-by: -

On arm64, pointer size and alignment is 64-bit, hence a 4-byte hole is present in between the enum_id and name members of the sh_pfc_pin structure. Get rid of this hole by sorting the structure's members by decreasing size. This saves up to 1.5 KiB per enabled SoC, and reduces the size of a kernel including support for all R-Car Gen3 SoCs by more than 10 KiB. This has no size impact on SH and arm32. Signed-off-by:
