This patch is in preparation for adding EINT support to MT7622 pinctrl, and the refactoring doesn't alter any existent logic. A reason we have to refactor EINT code pieces into a generic way is that currently, they're tightly coupled with a certain type of MediaTek pinctrl would cause a grown in a very bad way as there is different types of pinctrl devices getting to join. Therefore, it is an essential or urgent thing that EINT code pieces are refactored to eliminate any dependencies across GPIO and EINT as possible. Additional structure mtk_eint_[xt, hw, regs] are being introduced for indicating how maps being designed between GPIO and EINT hw number, how to set and get GPIO state for a certain EINT pin, what characteristic on a EINT device is present on various SoCs.

Merge tag 'samsung-pinctrl-4.18-2' of https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung into devel Samsung pinctrl drivers changes for v4.18 1. Driver expects specific order of GPIO interrupt banks. For S5Pv220 and Exynos5410 this order was not preserved so fix and document it. 2. Remove support for Exynos5440 (tree-wide, support is dropped because there are no real users of this platform, it also did not get testing since long time). 3. Fix lost state of GPF1..5 pins on Exynos5433 during system suspend.

GPF1..5 banks in Exynos5433 are located in two pinctrl devices: ALIVE and IMEM. Although they are partially located in ALIVE section, the state of their registers in IMEM section is lost after suspend/resume cycle. To properly handle such case, those banks have to be defined with standard 'exynos5433_bank_type_off' type (with PINCFG_TYPE_CON_PDN and PINCFG_TYPE_PUD_PDN register offsets). This automatically instructs the generic Samsung pinctrl suspend/resume code to save and restore state of those registers. Signed-off-by:

The comment block explaining the rationale for static pins contains grammar errors. It appeared first in the pin control driver for R-Car H3 ES1.x, and spread to R-Car M3-W, H3 ES2.0, and M3-N later. Fix the grammar in all copies at once. Signed-off-by:

Could only support PIN_CONFIG_INPUT_DEBOUNCE now as the HW block is too simple to support others. But even wrt. debounce capability, it now could only support very limited period of time to satisfy the real usecase. But still be useful to enable the crippled HW debounce to prevent any spurious glitches from waking up the system if the gpio is conguired as wakeup interrupt source. Signed-off-by:

The Armada 98dx3236 SoCs don't have a different MPP sel value for nand specific pins so "dev" was technically correct. But all the other Armada SoCs use "nand" in their dts and the pin is specific to the nand interface so use "nand" for the function name. Signed-off-by:

This adds a pair of context save/restore functions to save/restore the state of a set of pinctrl registers. The context is lost during rtc only suspend with ddr in self-refresh on am43xx. Currently the save/restore is being done unconditionally. This will be optimized later with a pdata-quirk function which will allow is to save/restore only when doing the rtc only mode with ddr in self refresh. Signed-off-by:

I was debugging some gpio issues and I thought that the output of gpio debugfs was telling me the high or low level of the gpios with a '1' or a '0'. We saw a line like this though: gpio93 : in 4 2mA pull down and I started to think that there may be a gas leak in the building because '4' doesn't mean high or low, and other pins said '0' or '1'. It turns out, '4' is the function selection for the pinmux of the gpio and not the value on the pin. Reading code helps decipher what debugfs is actually saying. Add support to read the input or output pin depending on how the pin is configured so we can easily see the high or low value of the pin in debugfs. Now the output looks like gpio93 : in low func4 2mA pull down which clearly shows that the pin is an input, low, with function 4 and a 2mA drive strength plus a pull down.
