Change the binding logic to ensure that the PMIC SPMI driver will run before the regulator code and add it to the building system. Signed-off-by:

Currently, an array is used to store both vsel and enable settings, mixing registers, masks and bit settings. Change it in order to have one separate property for each. This makes easier to understand the contents of the DT file, and to describe it at the Documentation/. Signed-off-by:

Without that, the regulator's core complains with: ldo17: ramp_delay not set For now, use the enable time, as we don't have any datasheets from this device. Signed-off-by: -

Using dev_dbg() is not too nice, as, instead of printing the name of the regulator, it prints "regulator.<number>", making harder to associate what is happening with each ldo line. So, add a debug-specific macro, which will print the rdev's name, just like the regulator core. Signed-off-by:

The regulator's core already handles it. Signed-off-by:

As the supported LDOs on this driver are all using a selector, change the implementation to use get_voltage_sel and set_voltage_sel ops. Signed-off-by:

Mauro Carvalho Chehab authored
Rename the functions used internally inside the driver in order for them to follow the driver's name. While here, get rid of some unused definitions at the header file. Signed-off-by:
-
Mauro Carvalho Chehab authored
Instead of implementing a custom set of properties, set valid_modes_mask based on having or not a mask for enabling the eco_mode. This makes the code clearer, and remove some uneeded props from DT. Signed-off-by:

Simplify the names of the OF properties, in order to make them similar to other drivers and to make easier to understand what each property means. Signed-off-by:

- use dev_foo() instead of pr_foo(); - cleanup the messages, making them more standard and easier to understand. Signed-off-by:

There are several fields on this struct that can be removed, as they already exists at struct regulator_desc. Remove them, cleaning up the code in the process. While here, rename it to hi6421v600_regulator_info, in order to better match the driver's name. Signed-off-by:

There are several issues on those drivers related to their coding style. Solve most of them. Signed-off-by:

Mauro Carvalho Chehab authored
The driver was originally written for Kernel 4.9. It needs to be ported to upstream: - Got rid of timeval; - Removed a bogus dependency; - Did cleanups at the header file. Signed-off-by:

Get rid of the sysfs code and other parts of the driver which aren't needed upstream. If needed later, this patch can be (partially?) reversed. Signed-off-by:

Add the regulator driver for the LDO lines provided by the HiSilicon 6421v600 SPMI PMIC device. [mchehab+huawei@kernel.org: keep just the regulator driver on this patch, renaming it to better fit at upstream namespace] The compete patch is at: https://github.com/96boards-hikey/linux/commit/08464419fba2Signed-off-by:

Checkpatch complains about some minor issues inside this driver that were not addressed by the previous patch. Address them. Signed-off-by:

There are several OF properties that aren't used by Hikey 970, and some are not even used inside the driver. So, drop them, as as this makes easier to document what's actually used. If latter needed, those could be re-added later. Signed-off-by:

Change the binding logic to ensure that the MFD driver will be load after having the SPMI controller registered. Signed-off-by:

There are several external vars that are defined there, which are not needed anymore. Get rid of them. Signed-off-by:

Mauro Carvalho Chehab authored
There are several static vars inside this driver. Get rid of them. While here, add a SPDX header file. Signed-off-by:
-
Mauro Carvalho Chehab authored
Several functions aren't used outside the mfd driver. So, either remove or make them static. Signed-off-by:

There are some checks there which could make sense for downstream builds, but doesn't make much sense for upstream ones. They came from the official Hikey970 tree from Linaro, but even there, the commented-out code is not set via other Kconfig vars. So, let's just get rid of that. If needed later, this patch can be (partially?) reversed. Signed-off-by:

Now that the driver was ported to upstream, add it as a SPMI controller. Signed-off-by:

Right now, driver is printing some messages as: [ 33.833026] (NULL device *): spmi_read_cmd: id:0 addr:0x17, read value: 00 This is because dev_foo() are not using a device with a name set. Change the logic for it to print it right. Signed-off-by:

It is interesting to be able to check if the driver is doing the right thing. So, add some debug macros to allow checking it. Signed-off-by:

Instead of manually using bswap_32(), just use the le32 macros. Signed-off-by:

Add a MODULE_DEVICE_TABLE() to the driver. Also, the current logic calls platform_set_drvdata(pdev, NULL) if the driver succeeds loading. While here, remove the .owner, as it is not needed upstream anymore. Signed-off-by:
