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

2018-01-01T14:04:19Z

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. Signed-off-by: Felix Brack Reviewed-by: Simon Glass

power: pmic/regulator: Add basic support for TPS65910

2017-12-13T02:53:45Z

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.

treewide: replace with error() with pr_err()

2017-10-04T15:59:44Z

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 (...) // Signed-off-by: Masahiro Yamada Reviewed-by: Simon Glass [trini: Re-run Coccinelle] Signed-off-by: Tom Rini

power: spl: add SPL_DM_REGULATOR_FIXED in Kconfig

2017-09-30T22:33:35Z

The Makefile already tests for SPL_DM_REGULATOR_FIXED, but Kconfig does not provide it. This adds SPL_DM_REGULATOR_FIXED to Kconfig. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

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

2017-09-22T14:23:54Z

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. Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Tom Rini Reviewed-by: Simon Glass

regulator: palmas: disable bypass when the LDO is enabled

2017-08-01T02:58:01Z

Some LDOs have a bypass capability. Make sure that the bypass is disabled when is the LDO is enabled (otherwise the voltage can't be changed). Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Keerthy Reviewed-by: Tom Rini
