regulator: Fix 88pm8607.c printk format warning

2011-05-26T17:47:29+00:00

Fix printk format warning (seen on x86_64) and change to unsigned
output format:

drivers/regulator/88pm8607.c:417: warning: format '%d' expects type 'int', but argument 3 has type 'resource_size_t'

mfd: Avoid to use constraint name in 88pm860x regulator driver

2011-05-26T17:45:38+00:00

Avoid to use constraint name in regulator driver. So use regulator id is used
instead in platform driver.

mfd: Use mfd cell platform_data for 88pm860x cells platform bits

2011-05-26T17:45:12+00:00

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

mfd: Adopt mfd_data in 88pm860x regulator

2011-03-23T09:42:06+00:00

Copy 88pm860x platform data into different mfd_data structure for
regulator driver. So move the identification of device node from
regulator driver to mfd driver.

regulator: Report actual configured voltage to set_voltage()

2011-01-12T14:32:59+00:00

Change the interface used by set_voltage() to report the selected value
to the regulator core in terms of a selector used by list_voltage().
This allows the regulator core to know the voltage that was chosen
without having to do an explict get_voltage(), which would be much more
expensive as it will generally access hardware.

regulator: 88pm8607 - fix value range checking for accessing info->vol_table

2010-09-05T10:15:52+00:00

In choose_voltage(), we use i as array index of info->vol_table.
The valid value range for i should be 0 .. ARRAY_SIZE(info->vol_table) - 1.

Take LDO1 as example, ARRAY_SIZE(LDO1_table) is 4, vol_nbits of LDO1 is 2.
for (i = 0; i < (2 << info->vol_nbits); i++)  is equivalent to
for (i = 0; i < 8; i++)
which is wrong.

The same value range checking also applies for index in pm8607_list_voltage().

regulator: use voltage number array in 88pm860x

2010-05-25T09:16:02+00:00

A lot of condition comparision statements are used in original driver. These
statements are used to check the boundary of voltage numbers since voltage
number isn't linear.

Now use array of voltage numbers instead. Clean code with simpler way.

regulator: make 88pm860x sharing one driver structure

2010-05-25T09:16:02+00:00

Remove a lot of driver structures in 88pm860x driver. Make regulators share
one driver structure.

regulator: Unsupport 88pm8607 A0 and A1

2010-03-07T21:17:06+00:00

Remove the support 88PM8607 A0/A1 stepping. There's some register
definition changes in B0 stepping. It can make software more efficient.
