rtc: ds1307: Add ds1339 compatible

2021-03-23T12:36:07+00:00

As far as u-boot is concerned the ds1339 is compatible with the other
devices supported by the ds1307 driver. The Linux driver does expose
some additional functionality but as far as u-boot is concerned just
adding the compatible string is enough.

sandbox: keep time offset when resetting

2021-01-30T21:25:42+00:00

The UEFI Self Certification Test (SCT) checks the SetTime() service with
the following steps:

* set date
* reset
* check date matches

To be compliant the sandbox should keep the offset to the host RTC during
resets. The implementation uses the environment variable
UBOOT_SB_TIME_OFFSET to persist the offset.

rtc: add rtc-abx80x, a driver for the Abracon AB x80x i2c rtc

2021-01-27T22:07:48+00:00

This is a basic driver for the ultra-low-power Abracon AB x80x series
of RTC chips. It supports in particular, the supersets AB0805 and AB1805.
It allows reading and writing the time, and enables the supercapacitor or
battery charger.

dm: Rename U_BOOT_DEVICE() to U_BOOT_DRVINFO()

2021-01-05T19:26:35+00:00

The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.

The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)

It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.

Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

dm: treewide: Rename ..._platdata variables to just ..._plat

2020-12-13T23:51:09+00:00

Try to maintain some consistency between these variables by using _plat as
a suffix for them.

dm: treewide: Rename ofdata_to_platdata() to of_to_plat()

2020-12-13T23:51:09+00:00

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

dm: treewide: Rename dev_get_platdata() to dev_get_plat()

2020-12-13T23:51:09+00:00

Rename this to be consistent with the change from 'platdata'.

dm: treewide: Rename 'platdata' variables to just 'plat'

2020-12-13T23:51:08+00:00

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
