soc: imx: gpc: fix power up sequencing

2020-04-23T08:38:05+00:00

[ Upstream commit e0ea2d11f8a08ba7066ff897e16c5217215d1e68 ] Currently we wait only until the PGC inverts the isolation setting before disabling the peripheral clocks. This doesn't ensure that the reset is properly propagated through the peripheral devices in the power domain. Wait until the PGC signals that the power up request is done and wait a bit for resets to propagate before disabling the clocks.

soc: imx-scu: Align imx sc msg structs to 4

2020-02-24T07:29:43+00:00

The imx SC api strongly assumes that messages are composed out of 4-bytes words but some of our message structs have odd sizeofs. This produces many oopses with CONFIG_KASAN=y. Fix by marking with __aligned(4). Fixes: 73feb4d0f8f1 ("soc: imx-scu: Add SoC UID(unique identifier) support") Signed-off-by: Leonard Crestez Signed-off-by: Shawn Guo

Pull ARM SoC driver updates from Olof Johansson: "Various driver updates for platforms: - A larger set of work on Tegra 2/3 around memory controller and regulator features, some fuse cleanups, etc.. - MMP platform drivers, in particular for USB PHY, and other smaller additions. - Samsung Exynos 5422 driver for DMC (dynamic memory configuration), and ASV (adaptive voltage), allowing the platform to run at more optimal operating points. - Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas - Clock/reset control driver for TI/OMAP - Meson-A1 reset controller support - Qualcomm sdm845 and sda845 SoC IDs for socinfo" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (150 commits) firmware: arm_scmi: Fix doorbell ring logic for !CONFIG_64BIT soc: fsl: add RCPM driver dt-bindings: fsl: rcpm: Add 'little-endian' and update Chassis definition memory: tegra: Consolidate registers definition into common header memory: tegra: Ensure timing control debug features are disabled memory: tegra: Introduce Tegra30 EMC driver memory: tegra: Do not handle error from wait_for_completion_timeout() memory: tegra: Increase handshake timeout on Tegra20 memory: tegra: Print a brief info message about EMC timings memory: tegra: Pre-configure debug register on Tegra20 memory: tegra: Include io.h instead of iopoll.h memory: tegra: Adapt for Tegra20 clock driver changes memory: tegra: Don't set EMC rate to maximum on probe for Tegra20 memory: tegra: Add gr2d and gr3d to DRM IOMMU group memory: tegra: Set DMA mask based on supported address bits soc: at91: Add Atmel SFR SN (Serial Number) support memory: atmel-ebi: switch to SPDX license identifiers memory: atmel-ebi: move NUM_CS definition inside EBI driver soc: mediatek: Refactor bus protection control soc: mediatek: Refactor sram control ...

soc: imx8mq: Read SOC revision from TF-A

2019-11-04T03:32:12+00:00

SOC revision on older imx8mq is not available in fuses so on anything other than B1 current code just reports "unknown". TF-A already handles this by parsing the ROM and exposes the value through a SMC call. Call this instead of reimplementing the workaround in the kernel itself.

soc: imx-scu: Using existing serial_number instead of UID

The soc_device_attribute structure already contains a serial_number attribute to show SoC's unique ID, just use it to show SoC's unique ID instead of creating a new file called soc_uid. Signed-off-by: Anson Huang Signed-off-by: Shawn Guo
