2022-08-31soc/mediatek/mt8188: Add SPM loader and initialize SPM in RAM stageRex-BC Chen
Add support for loading SPM firmware from CBFS to SPM SRAM. SPM needs its own firmware to enable SPM suspend/resume function which turns off several resources such as DRAM/mainpll/26M clk when linux system suspend. SPM is an essential component on MediaTek SoC, so we initialize PPM in soc_init(). For MT8188, SPM will handshake with DPM to do initialization, so we need to call spm_init() after dpm_init(). This SPM flow adds 33ms to the boot time. firmware log: mtk_init_mcu: Loaded (and reset) spm_firmware.bin in 25 msecs SPM: spm_init done in 33 msecs, spm pc = 0x400 TEST=spm pc is 0x400 which is in idle state.

2022-05-02soc/mediatek/mt8186: Prevent early USB wakeupRex-BC Chen
The MT8186 platform fails to suspend due to premature wakeup by USB. In MT8186, we use low level latch to keep USB wakeup signal. However, hardware could latch a wrong signal if it debounces more than one time. As a result, it would enable wakeup function too early. To prevent this issue, we do the following modification: - Delay about 100 us to enable wakeup function in kernel drivers [1]. - To guarantee 100 us is enough, we need to disable the USB debounce by default in coreboot. According to section register 0x404 and 0x420 in "(CODA) MT8169_PERICFG_REG.xls" which is only for MediaTek internal use: The current default value of debounce register for MT8186 USB IP0 and IP1 is incorrect. The reason we add in coreboot is that the default value should be correct when SoC is booting up. This modification is only for MT8186. The subsequent SoCs will adjust the wakeup function to correct register value by default.

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.
