2020-12-04pinctrl: at91-pio4: Make PINCTRL_AT91PIO4 depend on HAS_IOMEM to fix build errorTiezhu Yang
If CONFIG_HAS_IOMEM is not set, devm_platform_ioremap_resource() will be not built in drivers/base/platform.c and then there exists a build error about undefined reference to "devm_platform_ioremap_resource" in pinctrl-at91-pio4.c under COMPILE_TEST and CONFIG_PINCTRL_AT91PIO4, make PINCTRL_AT91PIO4 depend on HAS_IOMEM to fix it.

2020-12-04pinctrl: mtk: Fix low level output voltage issueZhiyong Tao
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".

2020-11-24pinctrl: at91-pio4: add support for fewer lines on last PIO bankEugen Hristev
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.

2020-11-13pinctrl: renesas: Protect GPIO leftovers by CONFIG_PINCTRL_SH_FUNC_GPIOGeert Uytterhoeven
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.

2020-11-13pinctrl: renesas: r8a7778: Use common R-Car bias handlingGeert Uytterhoeven
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.

2020-11-13pinctrl: renesas: Optimize sh_pfc_pin_configGeert Uytterhoeven
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.

Get rid of this hole by sorting the structure's members by decreasing size.

2020-11-12pinctrl: merrifield: Set default bias in case no particular value givenAndy Shevchenko
When GPIO library asks pin control to set the bias, it doesn't pass any value of it and argument is considered boolean (and this is true for ACPI GpioIo() / GpioInt() resources, by the way). Thus, individual drivers must behave well, when they got the resistance value of 1 Ohm, i.e. transforming it to sane default. In case of Intel Merrifield pin control hardware the 20 kOhm sounds plausible because it gives a good trade off between weakness and minimization of leakage current (will be only 50 uA with the above choice).

2020-11-12pinctrl: jasperlake: Fix HOSTSW_OWN offsetEvan Green
GPIOs that attempt to use interrupts get thwarted with a message like: "pin 161 cannot be used as IRQ" (for instance with SD_CD). This is because the HOSTSW_OWN offset is incorrect, so every GPIO looks like it's owned by ACPI.

2020-11-12pinctrl: jasperlake: Unhide SPI group of pinsAndy Shevchenko
If the group of pins is hidden in the pin list it affects the register offset calculation despite fixed GPIO base. Hence, the offsets of all pins after the hidden group are broken. Instead we have to unhide the group and use a flag to exclude it from GPIO number space.

It appears that pin configuration for GPIO chip hasn't been enabled yet due to absence of ->set_config() callback. Enable it here for Intel Lynxpoint PCH.

2020-11-12pinctrl: lynxpoint: Use defined constant for disabled bias explicitlyAndy Shevchenko
We have a specific constant to describe a disabled bias, i.e. GPIWP_NONE. Use it explicitly instead of making an assumption about its value. While at it, move argument assignment to the switch-case in lp_pin_config_get().
