power: tps65910: replace error() by pr_err()

2018-01-01T14:04:19+00:00

The patch replaces the former error() by the new pr_err().
This makes the TPS65910 driver conform to Masahiro's patch
'treewide:replace with error() with pr_err()' introduced
October 2017.

power: pmic/regulator: Add basic support for TPS65910

2017-12-13T02:53:45+00:00

Texas Instrument's TPS65910 PMIC contains 3 buck DC-DC converts, one
boost DC-DC converter and 8 LDOs. This patch implements driver model
support for the TPS65910 PMIC and its regulators making the get/set
API for regulator value/enable available.
This patch depends on the patch "am33xx: Add a function to query MPU
voltage in uV" to build correctly. For boards relying on the DT
include file tps65910.dtsi the v3 patch "power: extend prefix match
to regulator-name property" and an appropriate regulator naming is
also required.

power: extend prefix match to regulator-name property

2017-12-13T02:53:45+00:00

This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

treewide: replace with error() with pr_err()

2017-10-04T15:59:44+00:00

U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// 
@@@@
-error
+pr_err
 (...)
//

power: spl: add SPL_DM_REGULATOR_FIXED in Kconfig

2017-09-30T22:33:35+00:00

The Makefile already tests for SPL_DM_REGULATOR_FIXED, but Kconfig
does not provide it.  This adds SPL_DM_REGULATOR_FIXED to Kconfig.

regulator: pbias: Add PBIAS regulator for proper voltage switching on MMC1

2017-09-22T14:23:54+00:00

In the TI SOCs a PBIAS cell exists to provide a bias voltage to the MMC1
IO cells. Without this bias voltage these I/O cells can not function
properly. The PBIAS cell is controlled by software.

palmas: Add support for powering different ldos

2017-09-11T20:19:37+00:00

It is not necessary that ldo1 is used to power on mmc.
So, add support for passing ldo registers for powering on mmc.
