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>

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.

Modify palmas_mmc1_poweron_ldo() API to set the voltage based on the
voltage parameter passed as argument instead of always setting it to
3.0V. This allows MMC1 to set the LDO1 regulator voltage to 3.3V or 1.8V.
1.8V is required to add support for UHS mode.

Convert this PMIC driver to driver model and fix up other users. The
regulator and GPIO functions are now handled by separate drivers.
Update nyan-big to work correct. Three boards will need to be updated by
the maintainers: apalis-tk1, cei-tk1-som. Also the TODO in the code re
as3722_sd_set_voltage() needs to be completed.

Since priv->init_voltage is an unsigned integer it can never be
negative. So the current code fails to detect a missing
'regulator-init-microvolt' property and instead misconfigures the
PWM device. Fix this by making the relevant members of
'struct pwm_regulator_info' signed integers.

Till now get_ldo_reg did a return &rk808_ldo[num - 1]; to return
the ldo register offset but didn't take into account that its
calling functions already created the ldo as ldo = dev->driver_data - 1.
This resulted in the setting for ldo8 writing to the register of ldo7
and so on. So fix this and get the correct ldo register data.

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.

Inside of
max77686_buck_volt2hex/max77686_buck_hex2volt/max77686_ldo_volt2hex we
check that the value we calculate is >= 0 however we declare 'hex' as
unsigned int making these always true. Mark these as 'int' instead. We
also move hex_max to int as they are constants that are 0x3f/0xff.
Given that the above functions are marked as returning an int, make the
variables we assign their return value to also be int to be able to
catch the error condition now. Reported by clang-3.8.
