mfd: altera-sysmgr: Call of_node_put() only when of_parse_phandle() takes a ref

2024-03-26T22:19:51Z

[ Upstream commit e28c28a34ee9fa2ea671a20e5e7064e6220d55e7 ] of_parse_phandle() returns a device_node with refcount incremented, which the callee needs to call of_node_put() on when done.

mfd: intel-lpss: Fix the fractional clock divider flags

[ Upstream commit 03d790f04fb2507173913cad9c213272ac983a60 ] The conversion to CLK_FRAC_DIVIDER_POWER_OF_TWO_PS uses wrong flags in the parameters and hence miscalculates the values in the clock divider.

mfd: cs42l43: Correct SoundWire port list

2024-01-25T23:35:49Z

[ Upstream commit 47b1b03dc56ebc302620ce43e967aa8f33516f6f ] Two ports are missing from the port list, and the wrong port is set to 4 channels. Also the attempt to list them by function is rather misguided, there is nothing in the hardware that fixes a particular port to one function. Factor out the port properties to an actual struct, fixing the missing ports and correcting the port set to 4 channels.

mfd: rk8xx: fixup devices registration with PLATFORM_DEVID_AUTO

2024-01-25T23:35:49Z

[ Upstream commit 4aedcd4aa61d536ca17e67ecd5bc5d42529164f4 ] Since commit 210f418f8ace ("mfd: rk8xx: Add rk806 support"), devices are registered with "0" as id, causing devices to not have an automatic device id and prevents having multiple RK8xx PMICs on the same system. Properly pass PLATFORM_DEVID_AUTO to devm_mfd_add_devices() and since it will ignore the cells .id with this special value, also cleanup by removing all now ignored cells .id values. Now we have the same behaviour as before rk806 introduction and rk806 retains the intended behavior.
