platform/x86: mlx-platform: Add support for next generation systems

2020-01-13T19:02:46Z

Add support for new Mellanox system types of basic class VMOD0010, containing new Mellanox systems equipped with new switch device Spectrum 3 (32x400GbE/64x200G/128x100G Ethernet switch). These are the Top of the Rack 1U/2U/4U systems, equipped with Mellanox Comex card and with the switch board with Mellanox Spectrum-3 device. This class of devices can be equipped with two PS units for 1U/2U or with four PS units for 4U systems. Signed-off-by: Vadim Pasternak Signed-off-by: Andy Shevchenko

platform/x86: mlx-platform: Add support for new capability register

2020-01-13T19:02:46Z

Add support for capability register, which contains information about the number of PS units equipped on the system and about minimum I2C frequency supported by the all system's I2C devices. Utilization of this register allows to avoid necessity of providing new system description, in case it differs in number of PS units or in minimal I2C frequency.

platform/x86: mlx-platform: Add support for new system type

2020-01-13T19:02:46Z

Add support for new Mellanox system types of basic class VMOD0009, containing Mellanox systems equipped with the switch devices Spectrum 1 (32x100GbE Ethernet switch) and Switch-IB/Switch-IB2 (36x100Gbe InfiniBand switch). These are the Top of the Rack system, equipped with Mellanox Comex card. Signed-off-by: Vadim Pasternak Signed-off-by: Andy Shevchenko

platform/x86: mlx-platform: Set system mux configuration based on system type

2020-01-13T19:02:46Z

Separate assignment for systems mux configuration based on system type, instead of setting the same configuration for the all. The motivation is to allow introduction of new systems types with the different mux topology. Signed-off-by: Vadim Pasternak Signed-off-by: Andy Shevchenko

platform/x86: mlx-platform: Add more definitions for system attributes

2020-01-13T19:02:46Z

Add new attributes for "next-generation" type systems: - Reset cause indication, when system reset has been caused by the platform reset request through CPLD, by AC power failure, by software power off request through CPLD. by signal asserted by SOC through ACPI register. It introduces more reset causes, which can be monitored after the reboots. - Setting and removing system VPD (EEPROM) hardware write protection. It allows to access VPD during production cycle and prevents VPD corruption on system in field. - Voltage regulator devices configuration update status and version. It allows to monitor configuration update status and current active version for such sort of devices. - PCIe ASIC reset disable - when set ASIC will go down upon PCIe root complex reset, otherwise ASIC will stay up during PCIe root complex reset. - System configuration Ids to provide system static topology identification, like system's static I2C topology, number and type of FPGA devices within the system and so on. Add the existing attribute for "iio" bank selection for system type "msn21xx". All the above attributes are exposed through "sysfs" by "mlxreg-io" driver.

platform/x86: mlx-platform: Cosmetic changes

2020-01-13T19:02:45Z

platform/x86: mlx-platform: Fix error handling in mlxplat_init()

2019-07-12T13:00:38Z

Add the missing platform_device_unregister() before return from mlxplat_init() in the error handling case. Fixes: 6b266e91a071 ("platform/x86: mlx-platform: Move regmap initialization before all drivers activation") Signed-off-by: Wei Yongjun Signed-off-by: Andy Shevchenko

platform/x86: mlx-platform: Add more reset cause attributes

2019-07-03T12:37:33Z

Add more attributes for reset cause indication for the cases when system reset has been caused by watchdog, BIOS reload and COMEX thermal shutdown. Signed-off-by: Vadim Pasternak Signed-off-by: Andy Shevchenko

platform/x86: mlx-platform: Modify DMI matching order

2019-07-03T12:37:33Z

Modify DMI matching order: perform matching based on DMI_BOARD_NAME before matching based on DMI_BOARD_VENDOR and DMI_PRODUCT_NAME in order to reduce the number of ‘dmi_table’ entries necessary for new systems support and keep matching order in logical way. For example, the existing check for DMI_PRODUCT_NAME with prefixes “MSN27", “MSN24”, "MSB” matches systems MSN2700-BXXXX, MSN2700-XXXX, MSN2410-BXXXX, MSB7800-XXXX, where ‘XXXX’ specifies some systems hardware flavors. At the same time these systems also matched by DMI_BOARD_NAME “VMOD0001”, because they all have the same platform configuration (LED, interrupt control, mux etcetera). New systems with different platform configuration, but with similar DMI_PRODUCT_NAME MSN2700-2XXXX, MSN2700-2XXXX, MSB7800-2XXXX are about to be added. These system have similar DMI_PRODUCT_NAME, since they have same ports configuration as their predecessors. All new systems will be matched by DMI_BOARD_NAME “VMOD0008”. With the change provided in the patch it is enough just to add “VMOD0008” match following natural after “VMOD0007”, otherwise “VMOD0008” or all “MSN2700-2XXXX”, “MSN2700-2XXXX”, “MSB7800-2XXXX” should be added on top of ‘mlxplat_dmi_table” in order to be matched before “MSN27", “MSN24”, "MSB”.

platform/x86: mlx-platform: Add regmap structure for the next generation systems

2019-07-03T12:37:33Z

Use separated regamp structures for old and next generation systems. Next generation systems don’t require write protection removing. Signed-off-by: Vadim Pasternak Signed-off-by: Andy Shevchenko
