Drivers, drivers and drivers. Not a single core change. Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot SoCs. As part of the modularization attempt, I applied one patch affecting the firmware subsystem as a functional (not syntactic/semantic) dependency and then it blew up in our face, so I had to revert it, bummer. It will come in later, through that subsystem, I guess. New drivers: - New driver for the Microchip Serial GPIO "SGPIO". - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver. New subdrivers: - Intel Lakefield subdriver. - Intel Elkhart Lake subdriver. - Intel Alder Lake-S subdriver. - Qualcomm MSM8953 subdriver. - Qualcomm SDX55 subdriver. - Qualcomm SDX55 PMIC subdriver. - Ocelot Luton SoC subdriver. - Ocelot Serval SoC subdriver. Modularization: - The Meson driver can now be built as modules. - The Qualcomm driver(s) can now be built as modules. Incremental improvements: - The Intel driver now supports pin configuration for GPIO-related configurations. - A bunch of Renesas PFC drivers have been augmented with support for QSPI pins, groups and functions. - Non-critical fixes to the irq handling in the Allwinner Sunxi driver" * tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (80 commits) pinctrl/spear: simplify the return expression of spear300_pinctrl_probe() pinctrl: mediatek: simplify the return expression of mtk_pinconf_bias_disable_set_rev1() dt-bindings: pinctrl: pinctrl-microchip-sgpio: Add irq support pinctrl: pinctrl-microchip-sgpio: Add irq support (for sparx5) pinctrl: qcom: Add sm8250 lpass lpi pinctrl driver dt-bindings: pinctrl: qcom: Add sm8250 lpass lpi pinctrl bindings pinctrl: qcom-pmic-gpio: Add support for pmx55 dt-bindings: pinctrl: qcom-pmic-gpio: Add pmx55 support pinctrl: pinctrl-microchip-sgpio: Mark some symbols with static keyword pinctrl: at91-pio4: Make PINCTRL_AT91PIO4 depend on HAS_IOMEM to fix build error pinctrl: mtk: Fix low level output voltage issue pinctrl: falcon: add missing put_device() call in pinctrl_falcon_probe() pinctrl: actions: pinctrl-s500: Constify s500_padinfo[] pinctrl: pinctrl-microchip-sgpio: Add OF config dependency pinctrl: pinctrl-microchip-sgpio: Add pinctrl driver for Microsemi Serial GPIO dt-bindings: pinctrl: Add bindings for pinctrl-microchip-sgpio driver pinctrl: at91-pio4: add support for fewer lines on last PIO bank pinctrl: sunxi: Always call chained_irq_{enter, exit} in sunxi_pinctrl_irq_handler pinctrl: sunxi: Mark the irq bank not found in sunxi_pinctrl_irq_handler() with WARN_ON pinctrl: sunxi: fix irq bank map for the Allwinner A100 pin controller ...

| * pinctrl: qcom: Add sm8250 lpass lpi pinctrl driverSrinivas Kandagatla2020-12-053-0/+707
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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).

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.

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".

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.

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.
