* gpiolib: fix gpio label generation with gpiod_getAhmad Fatoum2023-04-111-1/+1
| | | | | | | | | | | Current mistaken use of con_id instead of _con_id, can lead to labels being called regulator.of-<NULL>. Fix this, so the label becomes regulator.of instead.

| * gpio: pca953x: add optional support for regulator and reset GPIOAhmad Fatoum2023-03-091-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, pca953x have a Power-On Reset mechanism that activates once supply voltage rises over threshold. Newer chips additionally feature a reset input. Add support for both. To not break existing boards, we will ignore failure to claim GPIO or regulator, even if it's just probe deferral. Boards wanting to make use of the newly parsed DT properties should enable deep probe.

* gpio: Add gpio latch driverSascha Hauer2022-11-083-0/+202
| | | | | | | | | | | | | This driver implements a GPIO multiplexer based on latches connected to other GPIOs. A set of data GPIOs is connected to the data input of multiple latches. The clock input of each latch is driven by another set of GPIOs. With two 8-bit latches 10 GPIOs can be multiplexed into 16 GPIOs. GPOs might be a better term as in fact the multiplexed pins are output only.

* gpio: allocate dynamic gpio numbers top downSascha Hauer2022-04-011-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | For GPIO controllers with dynamic GPIO number bases a free base is searched for bottom up. This means that GPIO controllers with fixed GPIO numbers must be registered before any controller with dynamic GPIO number base is registered, because otherwise the GPIO controllers with fixed GPIO numbers find their range occupied and can't be registered anymore. The probe order normally makes sure the SoC internal GPIO controllers with fixed numbers are registered first. With deep probe enabled we can't rely on the probe order anymore, so we need another solution. With this patch a free GPIO number range is searched for top down intead of bottom up, so as long as we have enough space in the ARCH_NR_GPIOS range the SoC internal GPIO controllers find their base unoccupied. GPIO controllers with dynamic GPIO numbers will change their numbers with this patch, but code shouldn't rely on these numbers anyway.

| | | | | | | | | | | | | | | | | | | | The gpio-mmio driver in Linux v5.12 has evolved quite a bit since the last sync. It now supports big endian byte order, 64-bit registers as well as controllers that have both a dirin and dirout register. The latter is particularly interesting, because it's required for the SiFive GPIO controller ported in a later patch. This commit also touches gpio-mpc8xxx used on the LS1046A. Because bit and byte endianness can now be configured separately, the driver needs adjustment. We don't seem to support any boards that have the peripheral as little-endian, but this is fixed by this commit. Comparing other bgpio_init users with Linux shows no need for further fixups.

* treewide: Use driver macroSascha Hauer2020-09-2915-77/+15
| | | | | | | We have several macros for a oneline driver registration. Add some missing and use them consistently where possible througout the tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* gpiolib: add gpio_array_to_id helper to get ID out of GPIO arrayOleksij Rempel2020-08-241-0/+31
| | | | | | | | | | | | | Some boards provide a board version and/or ID coded by pull-up/down resistors connected to the gpio pins (or pins which can be multiplexed at some point as gpio). In this case every one implements own gpio id reader function. To avoid it, provide the common helper function to extract a value out of provided gpio array.

| * treewide: remove stale instances of struct deviceAhmad Fatoum2020-08-031-1/+0
| | | | | | | | | | | | | | | | We call it struct device_d, any instances of struct device are likely left-over code after porting from Linux. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | gpio: get function returns masked register valueRenaud Barbier2020-08-031-1/+1
|/ | | | | | | | | | Unlike Linux the generic driver get function returns the masked register content and not the 0 or 1 value. The consequence is that gpio_get_value returns for instance 0x10 for bit 4 instead of 1. Use the Linux normalized form instead.
