2020-11-24pinctrl: at91-pio4: add support for fewer lines on last PIO bankEugen Hristev1-2/+16
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.

2020-11-24pinctrl: sunxi: Always call chained_irq_{enter, exit} in ↵Yangtao Li1-2/+4
sunxi_pinctrl_irq_handler 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().

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.

2020-11-13pinctrl: renesas: Protect GPIO leftovers by CONFIG_PINCTRL_SH_FUNC_GPIOGeert Uytterhoeven3-3/+11
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 Uytterhoeven2-40/+10
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".

2020-11-13pinctrl: renesas: r8a7778: Use physical addresses for PUPR regsGeert Uytterhoeven1-15/+9
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.

2020-11-13pinctrl: renesas: Optimize sh_pfc_pin_configGeert Uytterhoeven1-6/+4
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.

2020-11-13pinctrl: renesas: Reorder struct sh_pfc_pin to remove holeGeert Uytterhoeven1-2/+2
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.

2020-11-12pinctrl: merrifield: Set default bias in case no particular value givenAndy Shevchenko1-0/+8
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).

2020-11-10pinctrl: qcom: Allow pinctrl-msm code to be loadable as a moduleJohn Stultz2-1/+4
Tweaks to allow pinctrl-msm code to be loadable as a module. This is needed in order to support having the qcom-scm driver, which pinctrl-msm calls into, configured as a module. This requires that we tweak Kconfigs selecting PINCTRL_MSM to also depend on QCOM_SCM || QCOM_SCM=n so that we match the module setting of QCOM_SCM.

2020-11-10pinctrl: qcom: Kconfig: Rework PINCTRL_MSM to be a depenency rather then a ↵John Stultz1-24/+24
selected config This patch reworks PINCTRL_MSM to be a visible option, and instead of having the various SoC specific drivers select PINCTRL_MSM, this switches those configs to depend on PINCTRL_MSM. This is useful, as it will be needed in order to cleanly support having the qcom-scm driver, which pinctrl-msm calls into, configured as a module. Without this change, we would eventually have to add dependency lines to every config that selects PINCTRL_MSM, and that would becomes a maintenance headache. We also add PINCTRL_MSM to the arm64 defconfig to avoid surprises as otherwise PINCTRL_MSM/IPQ* options previously enabled, will be off.

2020-11-10pinctrl: ingenic: Add lcd-8bit group for JZ4770Paul Cercueil1-1/+8
Add the "lcd-8bit" group to the "lcd" function. As "lcd-24bit" is a superset of "lcd-8bit", in theory the former could be modified to only contain the pins not already included in "lcd-8bit", just like how it's done for the JZ4740 and JZ4725B platforms. However, we can't do that without breaking Device Tree ABI, so in that case we have no choice but to have two groups containing the same pins.

2020-11-10pinctrl: ingenic: Get rid of repetitive dataPaul Cercueil1-811/+447
Abuse the pin function pointer to store the pin function value directly, when all the pins of a group have the same function value. Now when the pointer value is <= 3 (unsigned), the pointer value is used as the pin function; otherwise it is used as a regular pointer. This drastically reduces the number of pin function tables needed, and drops .data usage by about 2 KiB. Additionally, the few pin function tables that are still around now contain u8 instead of int, since the largest number that will be stored is 3.
