extcon: Switch i2c drivers back to use .probe()

2023-06-01T14:42:28+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

extcon: sm5502: Drop useless mask_invert flag on irqchip

2022-07-15T02:37:41+00:00

There's no need to set the flag explicitly to false, since that is the default value from zero initialization. Signed-off-by: Aidan MacDonald Signed-off-by: Chanwoo Choi

extcon: sm5502: Clarify SM5703's i2c device ID

2022-05-13T08:03:41+00:00

While SM5502 and SM5504 are purely micro USB switching circuits, SM5703 is a multi-function device which has multiple modules in it. Change the i2c_device_id of it to avoid conflict with MFD driver. Signed-off-by: Markuss Broks Signed-off-by: Chanwoo Choi

extcon: sm5502: Add support for SM5703

2022-05-13T08:03:40+00:00

SM5703 is another MFD from Silicon Mitus which has a very similar MUIC unit to the one in SM5502. The only difference I've noticed is slightly different configuration only enables the interrupts which are exactly the same as on SM5502. If we make use of different interrupts in the future, this can be improved by having a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter) is working properly.

extcon: sm5502: Add support for SM5504

2021-06-21T09:28:01+00:00

SM5504 is another MUIC from Silicon Mitus that is fairly similar to SM5502. They seem to use the same register set, but: - SM5504 has some additional bits in SM5502_REG_CONTROL - SM5504 has a quite different set of interrupts - SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7) Overall it's minor and we can support this by defining a separate struct sm5502_type for SM5504.

extcon: sm5502: Refactor driver to use chip-specific struct

2021-06-21T09:28:01+00:00

Prepare for supporting SM5504 in the extcon-sm5502 driver by replacing enum sm5504_types with a struct sm5504_type that stores the chip-specific definitions. This struct can then be defined separately for SM5504 without having to add if (type == TYPE_SM5504) everywhere in the code. Signed-off-by: Stephan Gerhold Signed-off-by: Chanwoo Choi

extcon: sm5502: Implement i2c_driver->probe_new()

2021-06-21T09:28:01+00:00

sm5022_muic_i2c_probe() does not use the i2c_device_id, so implement i2c_driver->probe_new() instead of probe(). Signed-off-by: Stephan Gerhold Signed-off-by: Chanwoo Choi

extcon: sm5502: Use devm_regmap_add_irq_chip()

2021-06-21T09:28:00+00:00

Use devm_regmap_add_irq_chip() to avoid having to remove the irqchip explicitly in sm5502_muic_i2c_remove(). Signed-off-by: Stephan Gerhold Signed-off-by: Chanwoo Choi

extcon: sm5502: Drop invalid register write in sm5502_reg_data

2021-06-21T09:28:00+00:00

When sm5502_init_dev_type() iterates over sm5502_reg_data to initialize the registers it is limited by ARRAY_SIZE(sm5502_reg_data). There is no need to add another empty element to sm5502_reg_data. Having the additional empty element in sm5502_reg_data will just result in writing 0xff to register 0x00, which does not really make sense.

extcon: sm5502: Detect OTG when USB_ID is connected to ground

2021-04-08T04:10:16+00:00

In it's curent state this driver ignores OTG adapters with ID pin connected to ground. This commit adds a check to set extcon into host mode when such OTG adapter is connected. Signed-off-by: Nikita Travkin Signed-off-by: Chanwoo Choi
