But GX-family chips (e.g. GXB, GXL and newer) supports also 128-bit chip ID. 128-bit chip ID consists 32-bit SoC version and 96-bit OTP data. This is the third attempt to publish data from the Amlogic secure monitor chipid call. After discussions with Neil Armstrong, it was decided to publish the chipid call results through the soc driver. Since soc_device_match cannot wait for the soc driver to load, and the secure monitor calls in turn depend on the sm driver, it was necessary to create a new driver rather than expand an existing one. In the patches, in addition to writing the driver: - convert commonly used structures and functions of the meson-gx-socinfo driver to a header file. - add secure-monitor references for amlogic,meson-gx-ao-secure sections in dts files of the a1, axg, g12, gx families. --- Changes V1 -> V2 [1]: - create cpu_id structure for socinfo variable - create meson_sm_chip_id for result of sm call - remove shared functions - move from funcs for bit operations to C bit fields Links: - [1] https://lore.kernel.org/linux-arm-kernel/202311242104.RjBPI3uI-lkp@intel.com/T/ Viacheslav Bocharov (3): soc: amlogic: meson-gx-socinfo: move common code to header file soc: amlogic: meson-gx-socinfo-sm: Add Amlogic secure-monitor SoC Information driver soc: amlogic: meson-gx-socinfo: add new definition for Amlogic A113X package drivers/soc/amlogic/Kconfig | 10 + drivers/soc/amlogic/Makefile | 1 + .../soc/amlogic/meson-gx-socinfo-internal.h | 121 +++++++++++ drivers/soc/amlogic/meson-gx-socinfo-sm.c | 192 ++++++++++++++++++ drivers/soc/amlogic/meson-gx-socinfo.c | 136 ++----------- 5 files changed, 338 insertions(+), 122 deletions(-) create mode 100644 drivers/soc/amlogic/meson-gx-socinfo-internal.h create mode 100644 drivers/soc/amlogic/meson-gx-socinfo-sm.c base-commit: 9fc1ccccfd8d53dc7936fe6d633f2373fc9f62e8
