imx: soc: Select REGMAP_MMIO

2021-10-05T05:54:44+00:00

The imx-gpcv2 driver needs Regmap MMIO. Select it, and fix:

  420 | static const struct regmap_range imx7_yes_ranges[] = {

ARM: imx: fix imx8m dependencies

2021-01-11T01:36:11+00:00

Selecting ARM_GIC_V3 on non-CP15 processors leads to build failures
like

arch/arm/include/asm/arch_gicv3.h: In function 'write_ICC_AP1R3_EL1':
arch/arm/include/asm/arch_gicv3.h:36:40: error: 'c12' undeclared (first use in this function)
   36 | #define __ICC_AP1Rx(x)   __ACCESS_CP15(c12, 0, c9, x)
      |                                        ^~~

Add a dependency to only enable the gic driver when building for
at an ARMv7 target, which is the closes approximation to the ARMv8
processor that is actually in this chip.

soc: imx: select ARM_GIC_V3 for i.MX8M

2020-07-13T08:42:32+00:00

Select ARM_GIC_V3, then it is able to use gic v3 driver in aarch32
mode linux on aarch64 hardware. For aarch64 mode, it not hurts
to select ARM_GIC_V3.

firmware: imx: Move i.MX SCU soc driver into imx firmware folder

2020-07-13T02:02:00+00:00

The i.MX SCU soc driver depends on SCU firmware driver, so it has to
use platform driver model for proper defer probe operation, since
it has no device binding in DT file, a simple platform device is
created together inside the platform driver. To make it more clean,
we can just move the entire SCU soc driver into imx firmware folder
and initialized by i.MX SCU firmware driver.

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.

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

Merge tag 'imx-drivers-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into arm/drivers

2019-06-25T12:43:40+00:00

i.MX driver changes for 5.3:
 - Add i.MX SCU based SoC bus driver for i.MX8QXP SoC support, which
   talks to SCU firmware for getting SoC ID and revision.
 - Update soc-imx8 bus driver to read imx8mm soc revision from anatop.
 - Add i.MX8MN SoC bus support into soc-imx8 driver.
 - Various small improvements on soc-imx8 bus driver.

soc: imx: Add SCU SoC info driver support

2019-06-03T12:30:37+00:00

Add i.MX SCU SoC info driver to support i.MX8QXP SoC, introduce
driver dependency into Kconfig as CONFIG_IMX_SCU must be
selected to support i.MX SCU SoC driver, also need to use
platform driver model to make sure IMX_SCU driver is probed
before i.MX SCU SoC driver.

With this patch, SoC info can be read from sysfs:

i.mx8qxp-mek# cat /sys/devices/soc0/family
Freescale i.MX

i.mx8qxp-mek# cat /sys/devices/soc0/soc_id
0x2

i.mx8qxp-mek# cat /sys/devices/soc0/machine
Freescale i.MX8QXP MEK

i.mx8qxp-mek# cat /sys/devices/soc0/revision
1.1
