This patchset adds driver for Richtek rt5033 chip The chip contains
switching charge mode Li-Ion/Li-Polymer battery charger, fuelgauge, regulators.
This patchset provides common support for accessing the device.
This patchset have been tested base on exynos board.
Changes in v8
- Add description of hardware.
- Move structure.
Changes in v7
- Use small description.
- Change some names for a variable.
- Revise of_device_id struct style.
Changes in v6
- Fix white space issue in mfd cell struct.
Changes in v5
- Change possible built as a module.
- Revise rt5033_dev mfd cell entry.
- Fix incorrect typo.
- Add module alias.
Changes in v4
- rt5033 regulator patch is applied by Mark Brown.
Changes in v3
- Correct sentence errors.
- Add author information the top of each drivers.
- Remove unnecessary pre-initialise, struct member(rt5033->i2c) and blink.
- Change some return check.
- Use bool and of_match_ptr().
Changes in v2:
- Remove volatile_reg callback. Because this driver not in use regmap cache.
- Remove unnecessary subnode of_compatible.
- Add definde for set high impedance mode of charger.
- Remove unnecessary device specific code.
- Fix wrong register name.
- Fix wrong error message.
- Fix return vallue at error case.
- Revise binding documentation.

* [PATCH v8 1/4] mfd: rt5033: Add Richtek RT5033 driver core. @ 2014-12-09 12:03 ` Beomho Seo 0 siblings, 0 replies; 13+ messages in thread From: Beomho Seo @ 2014-12-09 12:03 UTC (permalink / raw) To: linux-kernel, linux-pm, devicetree Cc: sameo, lee.jone, lgirdwood, broonie, sre, dbaryshkov, dwmw2, robh+dt, pawel.moll, mark.rutland, ijc+devicetree, galak, cw00.choi, geunsik.lim, inki.dae, sw0312.kim, Beomho Seo This patch adds a new driver for Richtek RT5033 driver. RT5033 is a Multifunction device which includes battery charger, fuel gauge, flash LED current source, LDO and synchronous Buck converter. It is interfaced to host controller using I2C interface. Cc: Samuel Ortiz <sameo@linux.intel.com> Cc: Lee Jones <lee.jone@linaro.org> Signed-off-by: Beomho Seo <beomho.seo@samsung.com> Acked-by: Chanwoo Choi <cw00.choi@samsung.com> --- Changes in v8 - Add description of hardware. - Move structure. Changes in v7 - Use small description. - Change some names for a variable. - Revise of_device_id struct style. Changes in v6 - Fix white space issue in mfd cell struct. Changes in v5 - Change possible built as a module. - Revise rt5033_dev mfd cell entry. - Fix incorrect typo. - Add module alias. Changes in v4 - none. Changes in v3 - Correct sentence errors. - Add author information the top of each drivers. - Remove unnecessary pre-initialise, struct member(rt5033->i2c) and blink. - Change some return check. - Use bool and of_match_ptr(). Changes in v2 - Remove volatile_reg callback. Because this driver not in use regmap cache. - Revmoe unnecessary subnode of_compatible. - Add define for set_high impedance mode of charger. --- drivers/mfd/Kconfig | 12 ++ drivers/mfd/Makefile | 1 + drivers/mfd/rt5033.c | 142 ++++++++++++++++++++ include/linux/mfd/rt5033-private.h | 260 ++++++++++++++++++++++++++++++++++++ include/linux/mfd/rt5033.h | 62 +++++++++ 5 files changed, 477 insertions(+) create mode 100644 drivers/mfd/rt5033.c create mode 100644 include/linux/mfd/rt5033-private.h create mode 100644 include/linux/mfd/rt5033.h diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index 2e6b731..9cd2af6 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -623,6 +623,18 @@ config MFD_RTSX_PCI types of memory cards, such as Memory Stick, Memory Stick Pro, Secure Digital and MultiMediaCard. +config MFD_RT5033 + tristate "Richtek RT5033 Power Management IC" + depends on I2C=y + select MFD_CORE + select REGMAP_I2C + help + This driver provides for the Richtek RT5033 Power Management IC, + which includes the I2C driver and the Core APIs.

So I hope this patch to be merged at your git repository. Another patch set(RT5033 regulator driver) have been merged on for-next branch of regulator git repository. https://git.kernel.org/cgit/linux/kernel/git/broonie/regulator.git/commit/?h=for-next&id=b1917578fd5d8efa67afa05a0d6d7e323f2802da Other patches(about charger, fuelgague and devicetree doc) will be re-sent to each maintainers.
