mei: make device disabled on stop unconditionally

2015-03-02T03:34:50+00:00

Set the internal device state to to disabled after hardware reset in stop flow.
This will cover cases when driver was not brought to disabled state because of
an error and in stop flow we wish not to retry the reset.

mei: me: release hw from reset only during the reset flow

2015-02-03T23:48:51+00:00

We might enter the interrupt handler with hw_ready already set,
but prior we actually started the reset flow.
To soleve this we move the reset release from the interrupt handler
to the HW start wait function which is part of the reset sequence.

mei: mask interrupt set bit on clean reset bit

2015-02-03T23:48:51+00:00

We should mask interrupt set bit when writing back
hcsr value in reset bit clean-up.

This is refinement for

mei: use uuid, me_addr tuple addressing also for flow control credits

2015-01-12T13:04:10+00:00

Add uuid, me_addr addressing also for flow control credits.
The only exception in cases for single buffer clients for which
the host address in flow credits response is always 0

To in order to deal with add/remove race between fw and driver clients
addressing we need to use [uuid, me_addr] tuple to address the clients

mei: bus: use ssize_t as the return type for send and receive

2015-01-12T13:04:10+00:00

Mei bus receive and send function may return either number
of transmitted bytes or errno.  It is better to use ssize_t
type for that purpose that mixing size_t with int.

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/.
