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).

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.

2020-11-10pinctrl: ingenic: Add lcd-8bit group for JZ4770Paul Cercueil
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 Cercueil
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.

2020-11-10pinctrl: qcom: Move clearing pending IRQ to .irq_request_resources callbackMaulik Shah
When GPIOs that are routed to PDC are used as output they can still latch the IRQ pending at GIC. As a result the spurious IRQ was handled when the client driver change the direction to input to starts using it as IRQ. Currently such erroneous latched IRQ are cleared with .irq_enable callback however if the driver continue to use GPIO as interrupt and invokes disable_irq() followed by enable_irq() then everytime during enable_irq() previously latched interrupt gets cleared. This can make edge IRQs not seen after enable_irq() if they had arrived after the driver has invoked disable_irq() and were pending at GIC. Move clearing erroneous IRQ to .irq_request_resources callback as this is the place where GPIO direction is changed as input and its locked as IRQ. While at this add a missing check to invoke msm_gpio_irq_clear_unmask() from .irq_enable callback only when GPIO is not routed to PDC.

2020-11-05pinctrl: mcp23s08: Use full chunk of memory for regmap configurationAndy Shevchenko
It appears that simplification of mcp23s08_spi_regmap_init() made a regression due to wrong size calculation for dev_kmemdup() call. It misses the fact that config variable is already a pointer, thus the sizeof() calculation is wrong and only 4 or 8 bytes were copied. Fix the parameters to devm_kmemdup() to copy a full chunk of memory.

2020-10-26pinctrl: intel: 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 pin control hardware the 5 kOhm sounds plausible because on one hand it's a minimum of resistors present in all hardware generations and at the same time it's high enough to minimize leakage current (will be only 200 uA with the above choice).

2020-10-26pinctrl: intel: Fix 2 kOhm bias which is 833 OhmAndy Shevchenko
2 kOhm bias was never an option in Intel GPIO hardware, the available matrix is: 000 none 001 1 kOhm (if available) 010 5 kOhm 100 20 kOhm As easy to get the 3 resistors are gated separately and according to parallel circuits calculations we may get combinations of the above where the result is always strictly less than minimal resistance. Hence, additional values can be: 011 ~833.3 Ohm 101 ~952.4 Ohm 110 ~4 kOhm 111 ~800 Ohm That said, convert TERM definitions to be the bit masks to reflect the above. While at it, enable the same setting for pull down case.
