2018-06-27power: pmic: Let PFUZE3000 see all 256 registersTrent Piepho2-2/+3
The PFUZE3000 uses registers addresses up to 0xff. The DM pfuze100 driver supports both pfuze100 and pfuze3000. Allow it to use the device type to return the correct number of registers. Also rename the too generic PMIC_NUM_OF_REGS enumeration value for pfuze3000 to match the other "PFUZE3000_" prefixed enumerations and the pfuze100 enumeration value PFUZE100_NUM_OF_REGS.

2018-05-18sandbox: Rewrite i2c_pmic_emul.c to support PMIC with 3 bytes transmissionLukasz Majewski1-14/+31
This change enables support for MC34708 PMIC in sandbox. Now we can emulate the I2C transfers larger than 1 byte. Notable changes for this driver: - From now on the register number is not equal to index in the buffer, which emulates the PMIC registers - The PMIC register's pool is now dynamically allocated up till 64 regs * 3 bytes each = 192 B Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>

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.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada19-61/+61
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().
