2021-04-14mfd: da9063: Support SMBus and I2C modeHubert Streidl1-0/+3
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.

2020-08-13mfd: da9063: Fix revision handling to correctly select reg tablesAdam Thomson1-5/+10
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.

2018-09-10mfd: da9063: Fix DT probing with constraintsPhilipp Zabel1-7/+9
Commit 1c892e38ce59 ("regulator: da9063: Handle less LDOs on DA9063L") reordered the da9063_regulator_info[] array, but not the DA9063_ID_* regulator ids and not the da9063_matches[] array, because ids are used as indices in the array initializer. This mismatch between regulator id and da9063_regulator_info[] array index causes the driver probe to fail because constraints from DT are not applied to the correct regulator: da9063 0-0058: Device detected (chip-ID: 0x61, var-ID: 0x50) DA9063_BMEM: Bringing 900000uV into 3300000-3300000uV DA9063_LDO9: Bringing 3300000uV into 2500000-2500000uV DA9063_LDO1: Bringing 900000uV into 3300000-3300000uV DA9063_LDO1: failed to apply 3300000-3300000uV constraint(-22) This patch reorders the DA9063_ID_* as apparently intended, and with them the entries in the da90630_matches[] array.

The PMIC_DA9063 is a complete misnomer, it denotes the value of the DA9063 chip ID register, so rename it as such. It is also the value of chip ID register of DA9063L though, so drop the enum as all the DA9063 "models" share the same chip ID and thus the distinction will have to be made using DT or otherwise.

Add the correct silicon variant code ID (0x5) to the driver. This new code is the 'production' variant code ID for DA9063. This patch will remove the older variant code ID which matches the pre-production silicon ID (0x3) for the DA9063 chip. There is also some small amount of correction done in this patch: it splits the revision code and correctly names it according to the hardware specification and moves the dev_info() call before the variant ID test.
