Currently all PFC registers lie in low 32-bit address space. Hence use u32 instead of unsigned long to store PFC register addresses in pinctrl tables. All calculations of virtual addresses use a phys_addr_t intermediate, so we know where to add an offset if the 32-bit assumption ever becomes false. While this doesn't impact 32-bit builds, it would save ca. 7 KiB on a 64-bit shmobile_defconfig kernel. Signed-off-by:

All other loops over sh_pfc_soc_info.data_regs[] use pinmux_data_reg.regwidth as the sentinel, which is safer as zero is never a valid regwidth value (reg could be zero if we start using it to store an offset). Signed-off-by:

As register and field widths and offsets are in the range 1..32, use unsigned int (mostly replacing unsigned long) to store them in local variables and for passing them around. Move to one variable per line, move variables to the beginning of the block where they are used, and drop superfluous initializations while we are at it. Signed-off-by:

Register and field widths are in the range 1..32. Storing them in the pinctrl data in (arrays of) unsigned long wastes space. This decreases the size of a (32-bit) shmobile_defconfig kernel supporting 7 SoCs by 26460 bytes. Signed-off-by:

The alive pin controller on exynos7 does not support external gpio interrupts. Hence, remove the eint_gpio_init call-back for it. This fixes the following error message seen during exynos7 boot-up: "samsung-pinctrl 10580000.pinctrl: irq number not available" Signed-off-by:

This adds the initial support of the Broadcom Cygnus GPIO/PINCONF driver that supports all 3 GPIO controllers on Cygnus including the ASIU GPIO controller, the chipCommonG GPIO controller, and the always-on GPIO controller. Basic PINCONF configurations such as bias pull up/down, and drive strength are also supported in this driver. Pins from the ASIU GPIO controller can be individually muxed to GPIO function, through interaction with the Cygnus IOMUX controller Signed-off-by:

Commit 3dac1918 ("pinctrl: imx: detect uninitialized pins") needs the values in struct imx_pin_reg to be -1. This has been done in a rather unorthodox way by setting the memory to 0xff using memset... Use a proper for loop to initialize the whole array with -1. Signed-off-by:

Both nvidia,io-hv and nvidia,rcv-sel represent the fact that a particular pin's IO buffers are configured to accept "high voltage" input signals. The TRM for different chips names the register field rcv-sel on older SoCs and io_hv on newer SoCs. Add the new naming option into the pinctrl driver so that DT files can use naming consistent with the TRM. This new property name will be documented in the patch that adds support for the new SoC.

Various non-semantic tweaks and layout/consistency fixes for existing Tegra pinctrl drivers. Move the definition of DRV_PINGROUP_REG() before the definition of PINGROUP() so that a future SoC driver can invoke the former from the latter. PINGROUP_BIT_Y(n) is just n, so replace it with n. Re-wrap the parameters to *PINGROUP(). Keep various enums sorted in the Tegra124 driver. Various white-space consistency fixes. These changes aim to update existing drivers to be consistent with future SoC drivers. While we could ignore these tweaks to the existing drivers, I'd like to keep everything as consistent as possible for easy comparison. Besides, I auto-generate the drivers, and maintaining special-cases to keep the differences in place is annoying. Signed-off-by:
