soc: imx8: select SOC_BUS

2020-04-17T15:20:44+00:00

Compile-testing the driver can result in a link failure when CONFIG_SOC_BUS is disabled: x86_64-linux-ld: drivers/soc/imx/soc-imx8m.o: in function `imx8_soc_init': soc-imx8m.c:(.init.text+0x28d): undefined reference to `soc_device_register' Select it from Kconfig, as we do from the other SoC drivers.

soc: imx: drop COMPILE_TEST for IMX_SCU_SOC

2020-03-16T03:44:40+00:00

With COMPILE_TEST, there will be build error, because IMX_SCU might be set to n, so drop COMPILE_TEST. Suggested-by: Shawn Guo Signed-off-by: Peng Fan Signed-off-by: Shawn Guo

soc: imx: gpc: fix power up sequencing

2020-03-16T03:39:02+00:00

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. Signed-off-by: Lucas Stach Signed-off-by: Shawn Guo

soc: imx: increase build coverage for imx8m soc driver

2020-03-16T03:39:02+00:00

The soc-imx8.c driver is actually for i.MX8M family, so rename it to soc-imx8m.c. Use CONFIG_SOC_IMX8M as build gate, not CONFIG_ARCH_MXC, to control whether build this driver, also make it possible for compile test. Default set it to y for ARCH_MXC && ARM64 Signed-off-by: Peng Fan Reviewed-by: Leonard Crestez Signed-off-by: Shawn Guo

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

soc: imx: gpcv2: include linux/sizes.h

2020-02-14T02:03:09+00:00

This header is included indirectly on arm/arm64 but not on x86 so CONFIG_COMPILE_TEST breaks. Fix by including directly. Signed-off-by: Leonard Crestez Signed-off-by: Shawn Guo
