2024-08-30mfd: rohm-bd9576: Constify read-only regmap structsJavier Carrasco1-3/+3
`bd957x_regmap`, `bd9576_irqs` and `bd9576_irq_chip` are not modified and can be declared as const to move its data to a read-only section.

2024-02-23mfd: rohm: Convert to use maple tree register cacheBo Liu1-1/+1
The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.

2023-08-18mfd: Explicitly include correct DT includesRob Herring1-1/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-06-15mfd: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
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.

2022-12-08mfd: rohm: Use dev_err_probe()Matti Vaittinen1-9/+8
The dev_err_probe() has (at least) following benefits over dev_err() when printing an error print for a failed function call at a device driver probe: - Omit error level print if error is 'EPRBE_DEFER' - Standardized print format for returned error - return the error value allowing shortening calls like: if (ret) { dev_err(...); return ret; } to if (ret) return dev_err_probe(...); Convert the ROHM BD71828, ROHM BD718x7 and ROHM BD9576 core drivers to use the dev_err_probe() when returned error is not hard-coded constant.

2022-12-08mfd: rohm-bd9576: Convert to i2c's .probe_new()Uwe Kleine-König1-3/+2
The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted.

2021-03-10mfd: bd9576: Add IRQ supportMatti Vaittinen1-5/+85
BD9573 and BD9576 support set of "protection" interrupts for "fatal" issues. Those lead to SOC reset as PMIC shuts the power outputs. Thus there is no relevant IRQ handling for them. Few "detection" interrupts were added to the BD9576 with the idea that SOC could take some recovery-action before error gets unrecoverable. Unfortunately the BD9576 interrupt logic was not re-evaluated. IRQs are not designed to be properly acknowleged - and IRQ line is kept active for whole duration of error condition (in comparison to informing only about state change). For above reason, do not consider missing IRQ as error. Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
