i2c: mux: reg: Simplify with dev_err_probe()

2020-09-18T21:02:03Z

Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and the error value gets printed. Signed-off-by: Krzysztof Kozlowski Acked-by: Peter Rosin Signed-off-by: Wolfram Sang

i2c: mux: demux-pinctrl: Fix an error handling path in 'i2c_demux_pinctrl_probe()'

2020-05-15T09:23:49Z

A call to 'i2c_demux_deactivate_master()' is missing in the error handling path, as already done in the remove function. Fixes: 50a5ba876908 ("i2c: mux: demux-pinctrl: add driver") Signed-off-by: Christophe JAILLET Signed-off-by: Wolfram Sang

i2c: mux: pca954x: Convert license to SPDX identifier

2020-05-11T19:23:23Z

Use a shorter SPDX identifier instead of pasting the whole license. While here, replace duplicating PCA954x with PCA984x. Signed-off-by: Andy Shevchenko Reviewed-by: Peter Rosin Signed-off-by: Wolfram Sang

i2c: mux: pca954x: Move device_remove_file() out of pca954x_cleanup()

2020-05-11T19:23:16Z

device_create_file() is called the last in ->probe() but pca954x_cleanup(), which is called earlier in error path, tries to remove never created file. Move device_remove_file() call outside of pca954x_cleanup() to make it slightly closer to what pca954x_init() is doing.

i2c: mux: pca954x: Make use of device properties

2020-05-11T19:23:03Z

Device property API allows to gather device resources from different sources, such as ACPI. Convert the drivers to unleash the power of device property API. Signed-off-by: Andy Shevchenko Reviewed-by: Peter Rosin Signed-off-by: Wolfram Sang

i2c: mux: pca954x: Refactor pca954x_irq_handler()

2020-05-11T19:21:34Z

Refactor pca954x_irq_handler() to: - use for_each_set_bit() macro - use IRQ_RETVAL() macro Above change makes code easy to read and understand. Signed-off-by: Andy Shevchenko Reviewed-by: Peter Rosin Signed-off-by: Wolfram Sang

i2c: mux: pca954x: support property idle-state

2020-01-03T14:00:53Z

This supports property idle-state,if present, overrides i2c-mux-idle-disconnect. My use cases: - Use the property idle-state to fix an errata on LS2085ARDB and LS2088ARDB. - Errata id: E-00013(board LS2085ARDB and LS2088ARDB revision on Rev.B, Rev.C and Rev.D). - About E-00013: - Description: I2C1 and I2C3 buses are missing pull-up. - Impact: When the PCA954x device is tri-stated, the I2C bus will float. This makes the I2C bus and its associated downstream devices inaccessible. - Hardware fix: Populate resistors R189 and R190 for I2C1 and resistors R228 and R229 for I2C3. - Software fix: Remove the tri-state option from the PCA954x driver(PCA954x always on enable status, specify a channel zero in dts to fix the errata E-00013).
