2022-03-18soc/mediatek/mt8186: Disable unused spm_thermalRex-BC Chen
In MT8186, we need to disable spm_thermal to prevent it from influencing other wdt status. There are two hardware pathes which are used for asserting watchdog from thermal. We can disable status of path 1 because status of path 2 is used. 1. Thermal -> SPM -> WDT 2.

2022-03-15i2c: Add configurable I2C transfer timeoutJes Klinke
This patch introduces CONFIG_I2C_TRANSFER_TIMEOUT_US, which controls how long to wait for an I2C devices to produce/accept all the data bytes in a single transfer. (The device can delay transfer by stretching the clock of the ack bit.) The default value of this new setting is 500ms. Existing code had timeouts anywhere from tens of milliseconds to a full second beween various drivers. Drivers can still have their own shorter timeouts for setup/communication with the I2C host controller (as opposed to transactions with I2C devices on the bus.) In general, the timeout is not meant to be reached except in situations where there is already serious problem with the boot, and serves to make sure that some useful diagnostic output is produced on the console.
