2017-12-28pinctrl: sunxi: fix a typo when merging A20 support to A10 driverIcenowy Zheng
When merging A20 pinctrl support to A10 pinctrl driver, the I2C function of PI3 is wrongly written as "i2c3" (it should be "i2c4"). Fix this typo.

2017-10-31pinctrl: sunxi: Disable strict mode for old pinctrl driversMaxime Ripard
Old pinctrl drivers will need to disable strict mode for various reasons, among which: - Some DT will still have a pinctrl group for each GPIO used, which will be rejected by pin_request. While we could remove those nodes, we still have to deal with old DTs. - Some GPIOs on these boards need to have their pin configuration changed (for bias or current), and there's no clear migration path Let's disable the strict mode on those SoCs so that there's no breakage.

2017-08-14pinctrl: sunxi: add support of R40 to A10 pinctrl driverIcenowy Zheng
R40 is said to be an upgrade of A20, and its pin configuration is also similar to A20 (and thus similar to A10). Add support for R40 to the A10 pinctrl driver.

2017-07-31pinctrl: sunxi: add a missing function of A10/A20 pinctrl driverIcenowy Zheng
The PH16 pin has a function with mux id 0x5, which is the DET pin of the "sim" (smart card reader) IP block. This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers. The newest A10 Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and it's discovered during implementing R40 pinctrl driver. Add it to the driver. As we now merged A20 pinctrl driver to the A10 one, we need to only fix the A10 driver now.

2017-05-29pinctrl: sunxi: add A20 support to A10 driverIcenowy Zheng
As A20 is designed as a pin-compatible upgrade of A10, their pin controller are very similar, and can share one driver. Add A20 support to the A10 driver. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Reviewed-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-11-04pinctrl: sunxi: make bool drivers explicitly non-modularPaul Gortmaker
None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get essentially the same change, so they are handled in batch. Changes are (1) use builtin_platform_driver, (2) use init.h header (3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE, and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We do delete the MODULE_LICENSE etc. tags since all that information is already contained at the top of each file in the comments.

2015-03-18pinctrl: sun4i: GPIOs configured as irq must be set to input before readingHans de Goede
On sun4i-a10, when GPIOs are configured as external interrupt the value for them in the data register does not seem to get updated, so set their mux to input (and restore afterwards) when reading the pin. Missed edges seem to be buffered, so this does not introduce a race condition. I've also tested this on sun5i-a13 and sun7i-a20 and those do not seem to be affected, the input value representation in the data register does seem to correctly get updated to the actual pin value while in irq mode there.

Move the pin description to a driver specific to be. This is one more step toward retiring pinctrl-sunxi-pins.h that used to define all the pins for all the Allwinner SoCs in a single header, that would have in turn result in having these structures in the final binary as many times as the header was included.
