2017-05-15reset: sti: Use devm_kcalloc() in syscfg_reset_controller_register()Markus Elfring
* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "devm_kcalloc". * Replace the specification of a data structure by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention. * Delete the local variable "size" which became unnecessary with this refactoring.

Support for STiH415/6 SoCs is being removed from the kernel because the platforms are obsolete. This patch removes the reset drivers for these SoC's. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2016-05-30reset: fix Kconfig menu to include reset drivers in sub-menuMasahiro Yamada
In "make menuconfig", reset drivers are currently lined up together with the reset sub-system menu, like this: -*- Reset Controller Support ---- < > Hi6220 Reset Driver (It also means, the menu "Reset Controller Support" is always empty.) "Hi6220 Reset Driver" should go into the sub-menu of the "Reset Controller Support".

2014-10-31reset: stih407: Add softreset, powerdown and picophy controllersPeter Griffin
This patch adds softreset, powerdown and picophy reset controllers for the STiH407 SoC. With this patch three new devices are registered: - 1. st,stih407-powerdown 2. st,stih407-softreset 3. st,stih407-picophyreset All three devices use system configuration registers mapped via regmap to perform the reset or powerdown. The powerdown controller also has an acknowledgement. A separate picophy reset controller manages the different reset channels within the picophy, which have a different polarity to the other system softresets. Managing these different picophy softreset channels is necessary to correctly handle resuming from suspend when USB2 devices are plugged into the USB3 port.

2014-03-11drivers: reset: STi SoC system configuration reset controller supportStephen Gallimore
This patch adds a reset controller implementation for STMicroelectronics STi family SoCs; it allows a group of related reset like controls found in multiple system configuration registers to be represented by a single controller device. System configuration registers are accessed through the regmap framework and the mfd/syscon driver. The implementation optionally supports waiting for the reset action to be acknowledged in a separate status register and supports both active high and active low reset lines. These properties are common across all the reset channels in a specific reset controller instance, hence all channels in a paritcular controller are expected to behave in the same way.
