2020-08-13mfd: da9063: Add support for latest DA silicon revisionAdam Thomson1-0/+1
This update adds new regmap tables to support the latest DA silicon which will automatically be selected based on the chip and variant information read from the device. Signed-off-by: Adam Thomson <Adam.Thomson.Opensource@diasemi.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
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.

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).

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.

2018-07-04mfd: da9063: Replace model with typeMarek Vasut1-1/+5
The model number stored in the struct da9063 is the same for all variants of the da9063 since it is the chip ID, which is always the same. Replace that with a separate identifier instead, which allows us to discern the DA9063 variants by setting the type based on either DT match or otherwise.

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.

Fix a missing DVC_RDY interrupt mask in struct regmap_irq definition. The original submission of this driver did not contain all interrupt masking definitions in the struct regmap_irq contained in the file da9063-irq.c The solution is to add a DA9063_IRQ_DVC_RDY entry to enum da9063_irqs list and to add the corresponding values to compensate for the missing mask bit in the static const struct regmap_irq da9063_irqs[] table.

Add register definitions for DA9063 AD (0x3) silicon variant ID the ability to choose the silicon variant at run-time using regmap configuration. This patch also adds RTC support for the AD silicon changes. It adds both BB and AD support as regmap ranges and then makes the distinction between the two tables at run-time. This allows both AD and BB silicon variants to be supported at the same time.

2014-03-19mfd: da9063: Add support for production silicon variant codeOpensource [Steve Twiss]1-1/+5
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.
