platform/mellanox: mlxreg-hotplug: Add support for new capability register

2020-01-13T19:02:46+00:00

Add support for capability register, which is used for detection of the actual number of interrupt capable components within the particular group, supported by the specific system. Such components could be for example the number of power units and interrupts related to these units. The motivation is to avoid adding a new code in the future in order to distinct between the systems type supported different number of the components like power supplies, FANs, ASICs, line cards.

platform_data/mlxreg: additions for Mellanox watchdog driver.

2019-03-02T14:28:19+00:00

There are two new fields added to mlxreg core structure: features - supported features of device and identity - device identity name. Add new defines for watchdog features. Signed-off-by: Michael Shych Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck

platform_data/mlxreg: Add capability field to core platform data

2019-01-26T19:08:25+00:00

Add capability field to "mlxreg_core_platform_data" structure. The purpose of this register is to provide additional info to platform driver through the atribute related capability register. Signed-off-by: Vadim Pasternak Signed-off-by: Darren Hart (VMware)

platform_data/mlxreg: Document fixes for core platform data

2019-01-26T19:08:25+00:00

Remove "led" from the description, since the structure "mlxreg_core_platform_data" is used not only for led data. Signed-off-by: Vadim Pasternak Signed-off-by: Darren Hart (VMware)

platform_data/mlxreg: Document fixes for hotplug device

2018-05-12T22:38:40+00:00

Remove redunadant description of label in struct mlxreg_hotplug_device. Change location of access_mode in struct mlxreg_hotplug_device. Signed-off-by: Vadim Pasternak Signed-off-by: Darren Hart (VMware)

platform/x86: mlx-platform: Add physical bus number auto detection

2018-03-23T23:14:29+00:00

mlx-platform does not provide a bus number to i2c-mlxcpld, assuming it is always one. On some x86 systems, other i2c drivers may probe before i2c-mlxcpld, causing bus one to be busy. Make mlx-platform determine which adapter number is free prior to activating i2c-mlxpld, adjusting the mux base numbers accordingly. Update the mlxreg-hotplug pdata similarly. This adds an explicit mlx-platform build dependency on I2C, update the Kconfig accordingly. Add the missing REGMAP dependency while we're at it.

platform/x86: mlx-platform: Add deffered bus functionality

2018-03-23T23:14:28+00:00

mlx-platform activates i2c-mux-reg, which creates buses needed by mlxreg-hotplug. If the mlxreg-hotplug probe runs before the i2c-mux-reg probe completes, it may attempt to connect a device to an adapter number that has not been created yet, and fail. Make mlx-platform driver record the highest bus number in mlxreg-hotplug platform data and defer mlxreg-hotplug probe until all the buses are created.

platform/mellanox: mlxreg-hotplug: Modify to use a regmap interface

2018-01-31T18:36:49+00:00

Restructure mlxreg header for unification of hotplug item definitions. Unify hotplug items to allow any kind of item (power controller, fan eeprom, psu eeprom, asic health) in common way. Use a hardware independent regmap interface, enabling the support of hotplug events over programmable devices attached to different bus types, such as I2C, LPC, or SPI. Add a device node to the mlxreg_core_data structure.
