2017-12-12power: pmic/regulator: Add basic support for TPS65910Felix Brack3-0/+107
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 Brack1-2/+9
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 Yamada14-37/+37
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>

2017-06-01dm: Rename dev_addr..() functionsSimon Glass1-1/+1
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.
