2020-11-27mfd: bcm590xx: Drop of_match_ptr from of_device_id tableKrzysztof Kozlowski1-1/+1
The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it is not relevant here). This fixes compile warning (!CONFIG_OF on x86_64): drivers/mfd/bcm590xx.c:95:34: warning: ‘bcm590xx_of_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2019-08-12mfd: bcm590xx: Convert to i2c_new_dummy_deviceWolfram Sang1-3/+3
Move from i2c_new_dummy() to i2c_new_dummy_device(), so we now get an ERRPTR which we use in error handling. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2016-11-29mfd: bcm590xx: Simplify a testChristophe JAILLET1-1/+1
'i2c_new_dummy()' does not return an error pointer, so the test can be simplified to be more consistent. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-04-19mfd: bcm590xx: Use devm_mfd_add_devices() for mfd_device registrationLaxman Dewangan1-9/+2
Use devm_mfd_add_devices() for MFD devices registration and get rid of .remove callback to remove MFD child-devices. This is done by managed device framework. CC: Matt Porter <mporter@linaro.org> Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2015-10-26mfd: bcm590xx: Remove unnecessary MODULE_ALIAS()Javier Martinez Canillas1-1/+0
The driver has a I2C device id table that is used to create the module aliases and also "bcm590xx" isn't a supported I2C id, so it's never used. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2014-05-21mfd: bcm590xx: Add support for secondary I2C slave addressMatt Porter1-14/+46
BCM590xx utilizes a secondary I2C slave address to access additional register space. Add support for the secondary address space by instantiating a dummy I2C device with the appropriate secondary I2C slave address. Also expose a secondary regmap register space so that MFD drivers can access this secondary i2c slave address space.
