soc: Add Amlogic SoC Information driver

2017-07-28T16:25:07+00:00

Amlogic SoCs have a SoC information register for SoC type, package type and revision information. This patchs adds support for this register decoding and exposing with the SoC bus infrastructure. Signed-off-by: Neil Armstrong Signed-off-by: Kevin Hilman

soc: renesas: Rework Kconfig and Makefile logic

2017-06-12T09:31:07+00:00

The goals are to: - Allow precise control over and automatic selection of which (sub)drivers are used for which SoC, - Allow adding support for new SoCs easily, - Allow compile-testing of all (sub)drivers, - Keep driver selection logic in the subsystem-specific Kconfig, independent from the architecture-specific Kconfig (i.e. no "select" from arch/arm64/Kconfig.platforms), to avoid dependencies. This is implemented by: - Introducing Kconfig symbols for all drivers and sub-drivers, - Introducing the Kconfig symbol SOC_RENESAS, which is enabled automatically when building for a Renesas ARM platform, and which enables all required drivers without interaction of the user, based on SoC-specific ARCH_* symbols, - Allowing the user to enable any Kconfig symbol manually if COMPILE_TEST is enabled, - Using the new Kconfig symbols instead of the ARCH_* symbols to control compilation in the Makefile, - Always entering drivers/soc/renesas/ during the build.

soc: imx: Add GPCv2 power gating driver

2017-04-07T11:37:07+00:00

Add code allowing for control of various power domains managed by GPCv2 IP block found in i.MX7 series of SoCs. Power domains covered by this patch are: - PCIE PHY - MIPI PHY - USB HSIC PHY - USB OTG1/2 PHY Support for any other power domain controlled by GPC is not present, and can be added at some later point. Testing of this code was done against a PCIe driver.

soc: fsl: add GUTS driver for QorIQ platforms

2016-11-29T08:17:20+00:00

The global utilities block controls power management, I/O device enabling, power-onreset(POR) configuration monitoring, alternate function selection for multiplexed signals,and clock control. This patch adds a driver to manage and access global utilities block. Initially only reading SVR and registering soc device are supported. Other guts accesses, such as reading RCW, should eventually be moved into this driver as well. Signed-off-by: Yangbo Lu Acked-by: Arnd Bergmann Signed-off-by: Ulf Hansson
