2018-01-24power: pmic: s2mps11: probe the regulator driverJaehoon Chung
Add the probe function to support the s2mps11 regulator driver. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Anand Moon <linux.amoon@gmail.com>
2018-01-24power: regulator: s2mps11: add a regulator driver for s2mps11Jaehoon Chung
exynos5422 has the s2mps11 PMIC. s2mps11 pmic has the 10-BUCK and 38-LDO regulators. Each IP and devices in exynos5422 can be controlled by each regulators. This patch is support for s2mps11 regulator driver. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Anand Moon <linux.amoon@gmail.com>

In order to discard this code when unused in SPL we need to guard the command with a check for CONFIG_SPL_BUILD and we rearrange the code slightly to make this cleaner. Cc: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Tom Rini <trini@konsulko.com>
2018-01-01power: tps65910: replace error() by pr_err()Felix Brack
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 <fb@ltec.ch> Reviewed-by: Simon Glass <sjg@chromium.org>
2017-12-12power: pmic/regulator: Add basic support for TPS65910Felix Brack
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.

2017-12-12power: extend prefix match to regulator-name propertyFelix Brack
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. Signed-off-by: Felix Brack <fb@ltec.ch> Reviewed-by: Simon Glass <sjg@chromium.org>
2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
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: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
