regulator: bd9571mwv: Convert device attribute to sysfs_emit()

2021-03-15T15:42:12Z

Convert the "backup_mode" device attribute from sprintf() to sysfs_emit(), as the latter is aware of the PAGE_SIZE buffer. Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20210312130242.3390038-4-geert+renesas@glider.be Signed-off-by: Mark Brown

regulator: bd9571mwv: Fix regulator name printed on registration failure

2021-03-15T15:42:11Z

If a regulator fails to register, the driver prints an error message like: bd9571mwv-regulator bd9571mwv-regulator.6.auto: failed to register bd9571mwv-regulator regulator However, the platform device's name is already printed as part of dev_err(), and does not allow the user to distinguish among the various regulators that are part of the PMIC. Fix this by printing regulator_desc.name instead, to change the message like: bd9571mwv-regulator bd9571mwv-regulator.6.auto: failed to register DVFS regulator Signed-off-by: Geert Uytterhoeven Reviewed-by: Matti Vaittinen Link: https://lore.kernel.org/r/20210312130242.3390038-3-geert+renesas@glider.be Signed-off-by: Mark Brown

regulator: bd9571mwv: Fix AVS and DVFS voltage range

2021-03-15T15:42:10Z

According to Table 30 ("DVFS_MoniVDAC [6:0] Setting Table") in the BD9571MWV-M Datasheet Rev. 002, the valid voltage range is 600..1100 mV (settings 0x3c..0x6e). While the lower limit is taken into account (by setting regulator_desc.linear_min_sel to 0x3c), the upper limit is not. Fix this by reducing regulator_desc.n_voltages from 0x80 to 0x6f.

regulator: mt6315: Fix off-by-one for .n_voltages

The valid selector is 0 ~ 0xbf, so the .n_voltages should be 0xc0. Signed-off-by: Axel Lin Link: https://lore.kernel.org/r/20210311020558.579597-1-axel.lin@ingics.com Signed-off-by: Mark Brown

regulator: rt4831: Fix return value check in rt4831_regulator_probe()

2021-03-10T12:22:27Z

In case of error, the function dev_get_regmap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

regulator: pca9450: Clear PRESET_EN bit to fix BUCK1/2/3 voltage setting

2021-03-10T12:22:26Z

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.
