2021-07-11regulator: hi6421: Fix getting wrong drvdataAxel Lin1-9/+13
Since config.dev = pdev->dev.parent in current code, so dev_get_drvdata(rdev->dev.parent) call in hi6421_regulator_enable returns the drvdata of the mfd device rather than the regulator. Fix it. This was broken while converting to use simplified DT parsing because the config.dev changed from pdev->dev to pdev->dev.parent for parsing the parent's of_node.

2020-07-22regulator: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

The hi6421-regulator driver consumes a similarly named platform device. Adding that to the module device table, allows modprobe to locate this driver once the device is created. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-08-21regulator: hi6421: Remove unused fields from struct hi6421_regulator_infoAxel Lin1-27/+4
The valid_modes_mask and *dev are not used in this driver, remove them. Current code uses devm_regulator_register, so we don't need *regulator in hi6421_regulator_info. Use a local variable instead. Also removes a few unnecessary inclusion of header files. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-08-16regulator: add driver for hi6421 voltage regulatorGuodong Xu1-0/+657
Add driver support for HiSilicon Hi6421 voltage regulators. Two rules for regulator enabling are defined in hi6421 spec: 1) Between disable and enable of each regulator (LDOs or BUCKs), there must be a protection gap. Use @off_on_delay of regulator core to implement this. 2) No two regulators can be enabled at the same time. Use mutex in hi6421_regulator_pdata to ensure this. A protection gap of 100us is added into each LDO/BUCK's .enable_time. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
