mfd: sec: Use devm_mfd_add_devices and devm_regmap_add_irq_chip

2016-05-09T12:27:38+00:00

Use devm_mfd_add_devices() for adding MFD child devices and
devm_regmap_add_irq_chip() for IRQ chip registration.

This reduces the error code path and .remove callback for removing
MFD child devices and deleting IRQ chip data.

mfd: sec: Add support for S2MPS15 PMIC

2015-11-23T10:33:16+00:00

Add support for S2MPS15 PMIC which is similar to S2MPS11 PMIC. The S2MPS15
PMIC supports 27 LDO regulators, 10 buck regulators, RTC, three 32.768KHz
clock outputs and battery charger. This patch adds initial support for
LDO and buck regulators of S2MPS15 device.

mfd: sec: Fix RTC alarm interrupt number on S2MPS11

2015-04-09T09:26:54+00:00

The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of
RTC alarms 0 and 1 were inversed between these two devices. So when
rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to
S2MPS11_IRQ_RTCA1, not RTCA0.

Fix this by using consistent RTC alarm interrupt numbers and adding a
BUILD_BUG_ON for future generations.

mfd: sec-core: Add support for S2MPS13 device

2014-11-25T15:55:01+00:00

This patch adds the support for Samsung S2MPS13 PMIC device to the sec-core MFD
driver. The S2MPS13 is very similar with existing S2MPS14 and includes PMIC/
RTC/CLOCK devices.

mfd: sec-core: Remove duplicated device type from sec_pmic_dev

2014-06-03T07:11:21+00:00

The device type was stored in sec_pmic_dev state container twice:
 - unsigned long type (initialized from of_device_id or i2c_device_id)
 - int device_type (initialized as above or from board files when there
   is no DTS)

The 'type' field was never used outside of probe so it can be safely
removed.

Change also the device_type in sec_pmic_dev and sec_platform_data to
unsigned long to avoid any casts.

mfd: sec: Add support for S2MPS14

2014-03-18T10:50:09+00:00

Add support for S2MPS14 PMIC device to the MFD sec-core driver.
The S2MPS14 is similar to S2MPS11 but it has fewer regulators, two
clocks instead of three and a little different registers layout.

mfd: sec-irq: Use consistent S2MPS11 RTC alarm interrupt indexes

2014-03-18T10:49:52+00:00

The S2MPS11 RTC has two alarms: alarm0 and alarm1 (corresponding
interrupts are named similarly). Use consistent names for interrupts to
limit possible errors.

mfd/rtc: s5m: fix register updating by adding regmap for RTC

2013-12-13T02:19:26+00:00

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.

On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC.  This could be observed in various hangs,
e.g.  in infinite loop during waiting for UDR field change.

On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.
