mei: clean reset bit before reset

2015-01-09T22:53:13+00:00

H_RST bit in H_CSR register may be found lit before reset is started,
for example if preceding reset flow hasn't completed.
In that case asserting H_RST will be ignored, therefore we need to clean
H_RST bit to start a successful reset sequence.

misc / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-05T01:56:02+00:00

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/misc/.

mei: export fw status registers through sysfs

2014-11-27T03:06:41+00:00

The interface is for applications that monitor
the fw health.

We use device_create_with_groups interface
to register attribute with the mei class device

ME devices prior to PCH8 (Lynx Point) have two FW status registers,
on PCH8 and newer excluding txe there are six FW status registers.

mei: fix hbm MEI_HBM_STARTED ambiguity

2014-11-07T17:59:08+00:00

We have MEI_HBM_STARTED in two contexts one
after start message was received and second
after enumeration was completed.
Because after start message reception we move
immediately to the enumeration state, we need
only the later meaning.

    mei: Remove all bus devices from the mei_dev list when stopping the MEI

    When stopping the MEI, we should remove and potentially unregister
    all bus devices queued on the mei_dev linked list.

We allocate nfc_dev and free it across the reset
so we do not keep it in dirty state

We have host client in connect/disconnect response processors,
so use client print functions to simplify and unify code.
