Calling RF calibrations when interface up, connection, switching bands and going to scan. For 8922AE, RF calibrations are moved to firmware, so use H2C commands to trigger RF calibrations and wait for a C2H event to indicate completion. Then, do next RF calibration. Signed-off-by:

TSSI is short for transmitter signal strength indication, which is a close-loop hardware circuit to feedback actual transmitting power as a reference to adjust power for next transmission. When connecting and switching bands or channels, do TSSI calibration and reset hardware status to output expected power. Signed-off-by:

RX DCK is receiver DC calibration. This will calibrate DC offset to reflect correct received signal strength indicator, so mechanisms like CCA can have normalized values. Signed-off-by:

IQ signal calibration is a basic and important calibration to yield good RF performance. Do this calibration on AP channel if we are going to connect. During scanning phase, it transmits with low data rate, so without IQK RF performance is still acceptable. Signed-off-by:

We are going to do RF calibrations in firmware, so driver needs to provide channel information for calibrations, which can do the same things as they did in driver. Signed-off-by:

The RF calibrations should be executed one by one, so add a completion to ensure one is finish before next. The report from C2H event contains state and optional version, and we only check the state for now. We also care about the time a RF calibration takes, so record start time before asking firmware to do calibration and get the delta time when receiving report. Consider SER recovery, we can't receive C2H event, use half of argument 'ms' as fixed delay that is 2 times of measured maximum time of calibrations. Signed-off-by:

Calling spi_sync() unconditionally sets the spi field of struct spi_message. Therefore setting msg.spi = spi before calling spi_sync() has no effect and can be removed. (spi_message_add_tail() does not access this field.) Signed-off-by:

The CW1200 uses two GPIOs to control the powerup and reset pins, get these from GPIO descriptors instead of being passed as platform data from boardfiles. The RESET line will need to be marked as active low as we will let gpiolib handle the polarity inversion. The SDIO case is a bit special since the "card" need to be powered up before it gets detected on the SDIO bus and properly probed. Fix this by using board-specific GPIOs assigned to device "NULL". There are currently no in-tree users. Signed-off-by:

As DSMs are going to be read from UEFI too, we need a unified API to get DSMs for both ACPI and UEFI. The difference in getting DSM in each one of these methods (ACPI, UEFI) is in the GUID, revision (0 for ACPI, 4 for UEFI), and size of the DSM values (8 or 32 for ACPI, 32 for UEFI). Therefore, change the iwl_acpi_get_dsm_x() to iwl_acpi_get_dsm() which determines the GUID, revision (these two are the same for all WiFi DSMs), and size (based on a func-to-size mapping) internally. While at it, fix DSM_FUNC_RFI_CONFIG to expect a 32-bit value (as defined in Intel BIOS spec) and not a 8-bit one. Signed-off-by:

Change iwl_acpi_get_eckv() to receive fwrt as argument so it will be the same as all iwl_acpi_get_x() functions, so it could be generated by the macro.
