2015-08-11	mfd: Export OF module alias information in missing drivers	Javier Martinez Canillas	1	-0/+1
	The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

2015-08-11	mfd: Drop owner assignment from i2c_drivers	Krzysztof Kozlowski	1	-1/+0
	i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2015-01-22	mfd: tps65218: Constify struct regmap_config	Krzysztof Kozlowski	1	-1/+1
	The regmap_config struct may be const because it is not modified by the driver and regmap_init() accepts pointer to const. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2015-01-20	mfd: tps65218: Make INT1 our status_base register	Felipe Balbi	1	-0/+1
	If we don't tell regmap-irq that our first status register is at offset 1, it will try to read offset zero, which is the chipid register.

2015-01-20	mfd: tps65218: Make INT[12] and STATUS registers volatile	Felipe Balbi	1	-0/+11
	STATUS register can be modified by the HW, so we should bypass cache because of that. In the case of INT[12] registers, they are the ones that actually clear the IRQ source at the time they are read. If we rely on the cache for them, we will never be able to clear the interrupt, which will cause our IRQ line to be disabled due to IRQ throttling.

2014-06-03	mfd: tps65218: Terminate of match table	Stephen Boyd	1	-0/+1
	Failure to terminate this match table can lead to boot failures depending on where the compiler places the match table. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-03-19	mfd: tps65218: Add driver for the TPS65218 PMIC	Keerthy	1	-0/+282
	The TPS65218 chip is a power management IC for Portable Navigation Systems and Tablet Computing devices. It contains the following components: - Regulators. - Over Temperature warning and Shut down. This patch adds support for tps65218 mfd device. At this time only the regulator functionality is made available.
