dt-bindings: mfd: bd71815: Fix rsense and typos

2025-02-08T08:51:52+00:00

[ Upstream commit 6856edf7ead8c54803216a38a7b227bcb3dadff7 ]

The sense resistor used for measuring currents is typically some tens of
milli Ohms. It has accidentally been documented to be tens of mega Ohms.
Fix the size of this resistor and a few copy-paste errors while at it.

Drop the unsuitable 'rohm,charger-sense-resistor-ohms' property (which
can't represent resistors smaller than one Ohm), and introduce a new
'rohm,charger-sense-resistor-micro-ohms' property with appropriate
minimum, maximum and default values instead.

regulator: dt-bindings: mt6315: Drop regulator-compatible property

2025-02-08T08:51:52+00:00

[ Upstream commit 08242719a8af603db54a2a79234a8fe600680105 ]

The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87b9 ("regulator: deprecate regulator-compatible DT
property"), which is so old it's not even mentioned in the converted
regulator bindings YAML file. It should not have been used for new
submissions such as the MT6315.

Drop the property from the MT6315 regulator binding and its examples.

dt-bindings: display: adi,adv7533: Drop single lane support

unsupported 1-lane from bindings.

dt-bindings: net: fec: add pps channel property

2024-12-27T12:58:58+00:00

commit 1aa772be0444a2bd06957f6d31865e80e6ae4244 upstream.

Add fsl,pps-channel property to select where to connect the PPS signal.
This depends on the internal SoC routing and on the board, for example
on the i.MX8 SoC it can be connected to an external pin (using channel 1)
or to internal eDMA as DMA request (channel 0).

ASoC: dt-bindings: mt6359: Update generic node name and dmic-mode

2024-12-09T09:32:01+00:00

[ Upstream commit 4649cbd97fdae5069e9a71cd7669b62b90e03669 ]

Some fix and updates in the following items:
1. examples:
Update generic node name to 'audio-codec' to comply with the
coming change in 'mt6359.dtsi'. This change is necessary to fix the
dtbs_check error:
pmic: 'mt6359codec' does not match any of the regexes: 'pinctrl-[0-9]+'

2. mediatek,dmic-mode:
After inspecting the .dts and .dtsi files using 'mt6359-codec', it was
discovered that the definitions of 'two wires' and 'one wire' are
inverted compared to the DT schema.
For example, the following boards using MT6359 PMIC:
- mt8192-asurada.dtsi
- mt8195-cherry.dtsi
These boards use the same definitions of 'dmic-mode' as other boards
using MT6358 PMIC. The meaning of '0' or '1' has been noted as comments
in the device trees.

Upon examining the code in [1] and [2], it was confirmed that the
definitions of 'dmic-mode' are consistent between "MT6359 PMIC" and
"MT6358 PMIC". Therefore, the DT Schema should be correct as is.
