mfd: Constify static struct resources

2020-11-19T08:34:21+00:00

Constify a number of static struct resource. The only usage of the
structs are to assign their address to the resources field in the
mfd_cell struct. This allows the compiler to put them in read-only
memory. Done with the help of Coccinelle.

mfd: tps65090: Make it explicitly non-modular

2019-02-01T08:21:13+00:00

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_TPS65090
drivers/mfd/Kconfig:    bool "TI TPS65090 Power Management chips"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

mfd: tps65090: Delete an error message for a failed memory allocation in tps65090_i2c_probe()

2018-05-16T08:21:48+00:00

Omit an extra message for a memory allocation failure in this function.

This issue was detected by using the Coccinelle software.

mfd: tps65090: Set regmap config reg counts properly

2016-03-16T08:50:36+00:00

Regmap config max_register field should contain number of
device last register, however num_reg_defaults_raw field
should be set to register count instead
(usually one register more than max_register).

tps65090 driver had both of these fields set to the same value,
fix this by introducing separate defines for max register
number and total count of registers.

mfd: Drop owner assignment from i2c_drivers

2015-08-11T14:08:48+00:00

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

mfd: tps65090: Fix bonkers indenting strategy

2014-11-25T16:18:53+00:00

First spotted pointless (incorrect) indent of 'if (ret)', then double
indentations of a struct attribute 'mask'.  Decided to go through the
whole file and make amendments instead and this is the result.

mfd: tps65090: Stop caching most registers

2014-04-23T11:32:19+00:00

Nearly all of the registers in tps65090 combine control bits and
status bits.  Turn off caching of all registers except the select few
that can be cached.

In order to avoid adding more duplicate #defines, we also move some
register offset definitions to the mfd driver (and resolve
inconsistent names).

mfd: tps65090: Don't tell child devices we have an IRQ if we don't

2014-04-23T11:23:25+00:00

If we weren't given an interrupt we shouldn't tell child devices (like
the tps65090 charger) that they have an interrupt.  This is needed so
that we can support polling mode in the tps65090 charger driver.

See also (charger: tps65090: Allow charger module to be used when no
irq).

mfd: ti: Constify struct mfd_cell where possible

2014-01-06T09:13:29+00:00

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.
