reset: simple: Enable for ASPEED systems

2018-02-21T04:57:04+00:00

ASPEED BMC SoCs have a reset controller in the LPC IP that can be controlled using this driver to release the UARTs from reset. No special configuration is required, so only the compatible string is added.

reset: socfpga: use the reset-simple driver

2018-02-20T03:39:01+00:00

Add reset line status readback, inverted status support, and socfpga device tree quirks to the simple reset driver, and use it to replace the socfpga driver. Signed-off-by: Philipp Zabel (cherry picked from commit adf20d7ce7c3591e049910c7760edd9c7da4a246) Signed-off-by: Joel Stanley

reset: add reset-simple to unify socfpga, stm32, sunxi, and zx2967

2018-02-20T03:39:00+00:00

Copy reusable parts from the sunxi driver, to add a driver for simple reset controllers with reset lines that can be controlled by toggling bits in exclusive, contiguous register ranges using read-modify-write cycles under a spinlock. The following patches will replace compatible reset drivers with reset-simple, extending it where necessary.

Pull ARM SoC driver updates from Arnd Bergmann: "New SoC specific drivers: - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later) based on the "BPMP" firmware - Clocksource and system controller drivers for the newly added Action Semi platforms (both arm and arm64). Reset subsystem, merged through arm-soc by tradition: - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini SoCs - Various subsystem-wide cleanups Updates for existing SoC-specific drivers - TI GPMC (General Purpose Memory Controller) - Mediatek "scpsys" system controller support for MT6797 - Broadcom "brcmstb_gisb" bus arbitrer - ARM SCPI firmware - Renesas "SYSC" system controller One more driver update was submitted for the Freescale/NXP DPAA data path acceleration that has previously been used on PowerPC chips.

reset: Add the TI SCI reset driver

2017-06-06T07:44:17+00:00

Some TI Keystone family of SoCs contain a system controller (like the Power Management Micro Controller (PMMC) on 66AK2G SoCs) that manage the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a reset driver that communicates to the system controller over the TI SCI protocol for performing reset management of various devices present on the SoC. Various reset functionalities are achieved by the means of different TI SCI device operations provided by the TI SCI framework. Signed-off-by: Andrew F.

reset: hi6220: Set module license so that it can be loaded

2017-05-24T08:53:41+00:00

The hi6220_reset driver can be built as a standalone module yet it cannot be loaded because it depends on GPL exported symbols. Lets set the module license so that the module loads, and things like the on-board kirin drm starts working. Signed-off-by: Jeremy Linton Reviewed-by: Xinliang Liu Signed-off-by: Philipp Zabel

reset: Add a Gemini reset controller

2017-05-24T08:46:13+00:00

The Cortina Systems Gemini reset controller is a simple 32bit register with self-deasserting reset lines. It is accessed using regmap over syscon. Acked-by: Philipp Zabel Signed-off-by: Linus Walleij Signed-off-by: Philipp Zabel

reset: ti_syscon: Rename TI_SYSCON_RESET to RESET_TI_SYSCON

Rename the current Kconfig name used for the TI SYSCON Reset driver from TI_SYSCON_RESET to RESET_TI_SYSCON to match the convention used for all the reset drivers present at the base reset folder. Signed-off-by: Suman Anna Signed-off-by: Philipp Zabel

reset: sti: Use devm_kcalloc() in syscfg_reset_controller_register()

2017-05-15T06:59:08+00:00

* 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.
