mfd: rk808: Split into core and i2c

2023-05-15T15:19:03+00:00

mfd: rk808: Replace 'struct i2c_client' with 'struct device'

2023-05-15T15:18:27+00:00

Put 'struct device' pointer into the MFD platform_data instead of the 'struct i2c_client' pointer. This simplifies the code and prepares the MFD for SPI support.

mfd: rk808: Use dev_err_probe

2023-05-15T15:17:58+00:00

Use dev_err_probe instead of dev_err in probe function, which simplifies code a little bit and prints the error code. Also drop possibly incorrect printing of chip id registers while touching the error message.

mfd: rk808: Re-add rk808-clkout to RK818

2023-02-22T08:25:51+00:00

Fixes RK818 (e.g. on Pinephone Pro) to register its clock, without which dependent devices (e.g. wifi/BT, via sdio-wifi-pwrseq) fail to probe. This line was removed in commit 3633daacea2e ("mfd: rk808: Permit having multiple PMIC instances"), but only from RK818.

mfd: rk808: Permit having multiple PMIC instances

2022-12-07T13:28:09+00:00

This set each cells id to PLATFORM_DEVID_NONE to allow multiple instances of each cell in case multiple PMICs handled by the rk808 driver are probed. This fixes probing a RK818 and a RK817 on the Odroid Go Ultra devices.

mfd: rk808: Convert to i2c's .probe_new()

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20221118224540.619276-454-uwe@kleine-koenig.org

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.
