[PATCH v3 01/10] mfd: intel_soc_pmic: Fix an error handling path in intel_soc_pmic_i2c_probe()

[Andy Shevchenko]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

The commit in Fixes: has added a pwm_add_table() call in the probe() and
a pwm_remove_table() call in the remove(), but forget to update the error
handling path of the probe.

Add the missing pwm_remove_table() call.

[PATCH v3 02/10] mfd: intel_soc_pmic_crc: Merge Intel PMIC core to crc

[Andy Shevchenko]

The core part is misleading since its only purpose to serve Crystal Cove PMIC,
although for couple of different platforms. Merge core part into crc one.

Advantages among others are:
- speed up a compilation and build
- decreasing the code base
- reducing noise in the namespace by making some data static and const

[PATCH v3 04/10] mfd: intel_soc_pmic_crc: Use devm_regmap_add_irq_chip()

[Andy Shevchenko]

Use devm_regmap_add_irq_chip() to simplify the code.

While at it, replace -1 magic parameter by PLATFORM_DEVID_NONE when
calling mfd_add_devices().

Note, the mfd_add_devices() left in non-devm variant here due to
potentially increased churn while wrapping pwm_remove_table().

[PATCH v3 05/10] mfd: intel_soc_pmic_crc: Convert to use i2c_get/set_clientdata()

[Andy Shevchenko]

We have the specific helpers for I2C device to set and get its driver data.
Convert driver to use them instead of open coded variants.

[PATCH v3 06/10] mfd: intel_soc_pmic_crc: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc

[Andy Shevchenko]

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based kernel configuration guards.

[PATCH v3 07/10] mfd: intel_soc_pmic_crc: Drop redundant ACPI_PTR() and ifdeffery

[Andy Shevchenko]

The driver depends on ACPI, ACPI_PTR() resolution is always the same.
Otherwise a compiler may produce a warning.

That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or
none should be used in a driver.

[PATCH v3 09/10] mfd: intel_soc_pmic_crc: Replace intel_soc_pmic with crystal_cove

[Andy Shevchenko]

To reflect the point that this driver is only for one type of the PMICs,
replace intel_soc_pmic with crystal_cove (avoid using crc for possible
namespace collisions with CRC library APIs).

Note, also rename the driver name since we don't expect any user
that enumerates by it, only ACPI known so far.
