mfd: arizona: Fix typo using hard-coded register

2017-06-06T09:17:42+00:00

A hardcoded register is accidentally used instead of the register
address passed into the function. Correct this and use the appropriate
variable. This would cause minor issues on wm5102, but all other
devices using this driver would have been unaffected.

mfd: axp20x: Support AXP803 variant

2017-04-27T10:54:49+00:00

AXP803 is a new PMIC chip produced by X-Powers, usually paired with A64
via RSB bus. The PMIC itself is like AXP288, but with RSB support and
dedicated VBUS and ACIN.

Add support for it in the axp20x mfd driver.

Currently only power key function is supported.

mfd: intel_soc_pmic_core: Fix unchecked return value

2017-04-27T10:54:47+00:00

unction devm_regmap_init_i2c() returns an ERR_PTR on errors, and its
return value should be checked before it is dereferenced. However, in
function intel_soc_pmic_i2c_probe(), the return value of function
devm_regmap_init_i2c() is used without validation. This patch fixes it.

mfd: menelaus: Remove obsolete local_irq_disable() and local_irq_enable()

2017-04-27T10:54:46+00:00

Since

commit e6229bec25be ("rtc: make rtc_update_irq callable with irqs enabled")

rtc_update_irq() is callable with irqs enabled, see the rtc drivers.
So update this accordingly.

mfd: omap-usb-tll: Configure ULPIAUTOIDLE

2017-04-27T10:54:45+00:00

The idle mode needs to be only disabled for UTMIAUTOIDLE while
ULPIAUTOIDLE can be enabled.

This matches the TLL_CHANNEL_CONF_i register configuration for ehci-tll
in the Motorola Linux kernel tree for Wrigley 3G LTE modem on droid 4
and the modem still stays responsive.

mfd: omap-usb-tll: Fix inverted bit use for USB TLL mode

2017-04-27T10:54:45+00:00

Commit 16fa3dc75c22 ("mfd: omap-usb-tll: HOST TLL platform driver")
added support for USB TLL, but uses OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF
bit the wrong way. The comments in the code are correct, but the inverted
use of OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF causes the register to be
enabled instead of disabled unlike what the comments say.

Without this change the Wrigley 3G LTE modem on droid 4 EHCI bus can
be only pinged few times before it stops responding.

mfd: lpc_ich: Add support for Intel Gemini Lake SoC

2017-04-27T10:54:43+00:00

Like Intel Apollo Lake, Gemini Lake exposes the serial SPI flash device BAR
through hidden P2SB PCI device. We use the same mechanism than Apollo Lake
to read the BAR and pass it to the driver.

mfd: hi655x: Add the clock cell to provide WiFi and Bluetooth

2017-04-27T10:54:43+00:00

The hi655x is a PMIC with regulator but also provides a clock for the WiFi
and the bluetooth which is missing in the current implementation.

Add the clock cell so it can be used in the next patch via the dts.

mfd: intel_soc_pmic: Fix a mess with compilation units

2017-04-27T10:54:42+00:00

Crystal Cove and Whiskey Cove are two different PMICs which are
installed on Intel Atom SoC based platforms.

Moreover there are two independent drivers that by some reason were
supposed (*) to get into one kernel module.

Fix the mess by clarifying Kconfig option for Crystal Cove and split
Whiskey Cove out of it.

(*) It looks like the configuration was never tested with
    INTEL_SOC_PMIC=n. The line in Makefile is actually wrong.
