* Merge tag 'samsung-pinctrl-4.18-2' of ↵Linus Walleij2018-05-246-1017/+51
|\ | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * pinctrl: samsung: Fix suspend/resume for Exynos5433 GPF1..5 banksMarek Szyprowski2018-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | This patch documents requirement coming from the way exynos_eint_gpio_irq() is working now, which expects EINTG banks to be at the beginning of the bank arrays.

| * pinctrl: samsung: Correct EINTG banks orderPaweł Chmiel2018-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All banks with GPIO interrupts should be at beginning of bank array and without any other types of banks between them. This order is expected by exynos_eint_gpio_irq, when doing interrupt group to bank translation. Otherwise, kernel NULL pointer dereference would happen when trying to handle interrupt, due to wrong bank being looked up. Observed on s5pv210, when trying to handle gpj0 interrupt, where kernel was mapping it to gpi bank.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a constant format without additional arguments, use seq_puts() instead of seq_printf(). Also, it fixes the following checkpatch warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code comments of PIN_FUNC_ID actually is not true for SHARE_MUX_CONF_REG case which should be a 4 u32 PIN_FUNC_ID. Fix the comments and re-org it a bit for better extendibility as we may add a different size for SCU based PIN_FUNC_ID later.
