a86854d0c treewide: devm_kzalloc() -> devm_kcalloc() ... Browse Code »

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

devm_kzalloc(handle, a * b, gfp)

with:
devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

devm_kzalloc(handle, a * b * c, gfp)

with:

devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

8f9165c98 regulator: tps65910: Work around silicon erratum SWCZ010 ... Browse Code »

http://www.ti.com/lit/pdf/SWCZ010:
DCDC o/p voltage can go higher than programmed value

Impact:
VDDI, VDD2, and VIO output programmed voltage level can go higher than
expected or crash, when coming out of PFM to PWM mode or using DVFS.

Description:
When DCDC CLK SYNC bits are 11/01:
* VIO 3-MHz oscillator is the source clock of the digital core and input
clock of VDD1 and VDD2
* Turn-on of VDD1 and VDD2 HSD PFETis synchronized or at a constant
phase shift
* Current pulled though VCC1+VCC2 is Iload(VDD1) + Iload(VDD2)
* The 3 HSD PFET will be turned-on at the same time, causing the highest
possible switching noise on the application. This noise level depends
on the layout, the VBAT level, and the load current. The noise level
increases with improper layout.

When DCDC CLK SYNC bits are 00:
* VIO 3-MHz oscillator is the source clock of digital core
* VDD1 and VDD2 are running on their own 3-MHz oscillator
* Current pulled though VCC1+VCC2 average of Iload(VDD1) + Iload(VDD2)
* The switching noise of the 3 SMPS will be randomly spread over time,
causing lower overall switching noise.

Workaround:
Set DCDCCTRL_REG[1:0]= 00.

b8b27a44d regulator: remove unnecessary of_node_get() to parent ... Browse Code »

These of_node_get() were added to balance refcount decrements inside of
of_find_node_by_name().
See: commit c92f5dd2c42f ("regulator: Add missing of_node_put()")

However of_find_node_by_name() was then replaced by of_get_child_by_name(),
which doesn't call of_node_put() against its input parameter.

So, need to remove these unnecessary of_node_get() calls.

As per the devicetree binding document of TPS65910, the "regulators"
subnode should be under the parent node, not outside of parent node.
Hence to get the regulator node, the correct call is
of_get_child_by_name() rather than of_find_node_by_name() which searches
the "regulators" node from the parent node to end of DTS file.

9fa8175f0 regulator: tps65910: Convert to use regulator_map_voltage_ascend ... Browse Code »

All regulators have ascendant voltage list in this driver.
Some regulators have more than 200 supported voltages.
e.g.
For TPS65910_REG_VDD1 and TPS65910_REG_VDD2:
n_voltages = VDD1_2_NUM_VOLT_FINE * VDD1_2_NUM_VOLT_COARSE
= 73 * 3
= 219

Thus it worth converting to regulator_map_voltage_ascend rather than use
default regulator_map_voltage_iterate.

For consistent, convert all regulators to regulator_map_voltage_ascend.

08337fdac regulator: tps65910: Fix using wrong dev argument for calling of_regulator_match ... Browse Code »

The dev parameter is the device requesting the data.
In this case it should be &pdev->dev rather than pdev->dev.parent.

The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(),
which means this fixes a memory leak because the memory is allocated every time
probe() is called, thus it should be freed when this driver is unloaded.

faa95fde4 regulator: tps65910: Remvoe tps65910_reg_[read|modify_bits|read_locked|write_locked] functions ... Browse Code »

The tps65910 mfd driver has been converted to regmap APIs.
This patch adds tps65910_reg_update_bits() in include/linux/mfd/tps65910.h.
Thus we can use tps65910_reg_read/tps65910_reg_write/tps65910_reg_update_bits
directly and remove tps65910_reg_[read|modify_bits|read_locked|write_locked]
functions. With this change, we can also remove the mutex in struct tps65910_reg.

7be531883 regulator: tps65910: correct init value of n_voltages ... Browse Code »

Recent change in the core driver to get the maximum voltage
is based on the (n_voltages -1) steps of voltage.
For the tps65910, the (n_voltages -1)th step voltage is
calculated based on the callback function list_voltage.
This function direct maps the datasheet and adjust the
first few steps for initial voltage as per datasheet,
and hence initialize the n_voltages based on datasheet.

f6442aa0b regulator: tps65910: Remove unused min_uV and max_uV from struct tps_info ... Browse Code »

The min_uV and max_uV fields of struct tps_info are not used in the code.
For the case voltage_table is provided, the min_uV and max_uV are the same
values as volt_table[0] and volt_table[n_voltages -1].
For the case voltage_table is not available, having the min_uV and max_uV seems
misleading. Current code uses equations to get the voltage value in this case,
but these equations do not use the min_uV and max_uV fields of struct tps_info.

Thus this patch removes the min_uV and max_uV fields from struct tps_info.

Pull MFD changes from Samuel Ortiz:
"Besides the usual cleanups, this one brings:

* Support for 5 new chipsets: Intel's ICH LPC and SCH Centerton,
ST-E's STAX211, Samsung's MAX77693 and TI's LM3533.

* Device tree support for the twl6040, tps65910, da9502 and ab8500
drivers.

* Fairly big tps56910, ab8500 and db8500 updates.

* i2c support for mc13xxx.

* Our regular update for the wm8xxx driver from Mark."

Fix up various conflicts with other trees, largely due to ab5500 removal
etc.

ldo2_reg: ldo2 {

Support the regulators functionality only when there is "regulators"
child node available for tps65910.
