mfd: da9063: Support SMBus and I2C mode

2021-04-14T15:06:05+00:00

By default the PMIC DA9063 2-wire interface is SMBus compliant. This means the PMIC will automatically reset the interface when the clock signal ceases for more than the SMBus timeout of 35 ms. If the I2C driver / device is not capable of creating atomic I2C transactions, a context change can cause a ceasing of the clock signal. This can happen if for example a real-time thread is scheduled. Then the DA9063 in SMBus mode will reset the 2-wire interface. Subsequently a write message could end up in the wrong register. This could cause unpredictable system behavior. The DA9063 PMIC also supports an I2C compliant mode for the 2-wire interface. This mode does not reset the interface when the clock signal ceases. Thus the problem depicted above does not occur. This patch tests for the bus functionality "I2C_FUNC_I2C". It can reasonably be assumed that the bus cannot obey SMBus timings if this functionality is set. SMBus commands most probably are emulated in this case which is prone to the latency issue described above. This patch enables the I2C bus mode if I2C_FUNC_I2C is set or otherwise keeps the default SMBus mode.

mfd: da9063: Fix revision handling to correctly select reg tables

2020-08-13T06:49:47+00:00

The current implementation performs checking in the i2c_probe() function of the variant_code but does this immediately after the containing struct has been initialised as all zero. This means the check for variant code will always default to using the BB tables and will never select AD. The variant code is subsequently set by device_init() and later used by the RTC so really it's a little fortunate this mismatch works. This update adds raw I2C read access functionality to read the chip and variant/revision information (common to all revisions) so that it can subsequently correctly choose the proper regmap tables for real initialisation.

mfd: da9063: Fix OTP control register names to match datasheets for DA9063/63L

2019-05-14T07:13:27+00:00

Mismatch between what is found in the Datasheets for DA9063 and DA9063L provided by Dialog Semiconductor, and the register names provided in the MFD registers file. The changes are for the OTP (one-time-programming) control registers. The two naming errors are OPT instead of OTP, and COUNT instead of CONT (i.e. control).
