There are no in-kernel users anymore, so remove this outdated interface.

2019-05-14mfd: da9063: Convert headers to SPDXWolfram Sang1-6/+2
Covnert the headers of the source and include files to SPDX. And fix some typos in the descriptions ("interrupt" instead of "I2C").

2018-07-04mfd: da9063: Register RTC only on DA9063LMarek Vasut1-7/+24
The DA9063L does not contain RTC block, unlike the full DA9063. Split the RTC block into separate mfd cell and register it only on DA9063. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2018-07-04mfd: da9063: Replace model with typeMarek Vasut1-1/+0
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.

2018-07-04mfd: da9063: Rename PMIC_DA9063 to PMIC_CHIP_ID_DA9063Marek Vasut1-1/+1
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.

Use devm_mfd_add_devices() instead of plain mfd_add_devices(), which removes the need for da9063_device_exit() altogether and also for the .remove callback in da9063-i2c.c . Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2015-06-22mfd: da9063: Add support for OnKey driverSteve Twiss1-0/+54
Add MFD support for the DA9063 OnKey driver The function da9063_clear_fault_log() is added to mitigate the case of a hardware power-cut after a long-long OnKey press. Although there is no software intervention in this case (by definition) such a shutdown would cause persistent information within the DA9063 FAULT_LOG that would be available during the next device restart. Clearance of this persistent register must be completed after such a hardware power-cut operation has happened so that the FAULT_LOG does not continue with previous values. The clearance function has been added here in the kernel driver because wiping the fault-log cannot be counted on outside the Linux kernel.

2014-07-28mfd: da9063: Add support for AD silicon variantOpensource [Steve Twiss]1-3/+3
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]1-11/+14
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.

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again. Hence make all cell data passed to mfd_add_devices() const where possible. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2013-08-20mfd: da9063: Add Dialog DA9063 core driverKrystian Garbaciak1-0/+129
This is MFD module providing access to registers and interrupts of DA906x series PMIC. It is used by other functional modules, registered as MFD cells. Driver uses regmap with paging to access extended register list. Register map is divided into two pages, where the second page is used during initialisation. This module provides support to following functional cells: - Regulators - RTC - HWMON - OnKey (power key misc input device) - Vibration (force-feedback input device) - Watchdog - LEDs Signed-off-by: Krystian Garbaciak <krystian.garbaciak@diasemi.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Reviewed-by: Mark Brown <broonie@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
