regulator: pca9450: Fix LDO3OUT and LDO4OUT MASK2023-06-19T14:13:17+00:00Teresa Remmett.remmet@phytec.de2023-06-14T12:52:40+00:00urn:sha1:7257d930aadcd62d1c7971ab14f3b1126356abdc
L3_OUT and L4_OUT Bit fields range from Bit 0:4 and thus the
mask should be 0x1F instead of 0x0F.

Make the I2C Level Translator included in PCA9450 configurable from
devicetree. The reset state is off. By setting nxp,i2c-lt-enable, the
I2C Level Translator will be enabled while in STANDBY or RUN state.

regulator: pca9450: Clear PRESET_EN bit to fix BUCK1/2/3 voltage setting2021-03-10T12:22:26+00:00Frieder Schrempffrieder.schrempf@kontron.de2021-02-22T11:52:20+00:00urn:sha1:98b94b6e38ca0c4eeb29949c656f6a315000c23e
The driver uses the DVS registers PCA9450_REG_BUCKxOUT_DVS0 to set the
voltage for the buck regulators 1, 2 and 3. This has no effect as the
PRESET_EN bit is set by default and therefore the preset values are used
instead, which are set to 850 mV.
To fix this we clear the PRESET_EN bit at time of initialization.

regulator: pca9450: Enable system reset on WDOG_B assertion2021-02-11T13:11:35+00:00Frieder Schrempffrieder.schrempf@kontron.de2021-02-11T10:55:30+00:00urn:sha1:f7684f5a048febd2a7bc98ee81d6dce52f7268b8
By default the PCA9450 doesn't handle the assertion of the WDOG_B
signal, but this is required to guarantee that things like software
resets triggered by the watchdog work reliably.
As we don't want to rely on the bootloader to enable this, we tell
the PMIC to issue a cold reset in case the WDOG_B signal is
asserted (WDOG_B_CFG = 10), just as the NXP U-Boot code does.
