- fini goes with init, so call it intel_power_domains_fini. While
at it shovel some of the fini code that leaked out of it back in.
- give power_enabled functions the verb _is_ to make the meaning clearer.
Also use a __ prefix instead of _unlocked to really discourage users.
- rename runtime_pm_init/fini to enable/disable since that's what they do.

Check in vlv_crtc_clock_get if DPLL is enabled before calling dpio read.

Functions that can't fail are such a bliss to work with, it'd be shame
to miss the occasion. The "failure" mode is the DSI connector not being

If we disable first the port (by disabling DPI) and only then the
display pipe the pipe-off flag will never be set, possibly leading to a
hanged pipe state at the next modeset-enable.
Note that according to the VLV2 display cluster HAS, we should disable
the port before the pipe. This doesn't seem to match reality based on
the above and it's also asymmetric with the enabling sequence, where we
first enable the port and then the pipe.

is the recommended sequence (Shobhit)

It seems by default the VBT has MIPI configuration block as well. The
Generic driver will assume always MIPI if MIPI configuration block is found.
This is causing probelm when actually there is eDP. Fix this by looking
into general definition block which will have device configurations. From here
we can figure out what is the LFP type and initialize MIPI only if MIPI
is found.
v2: Addressed review comments by Damien
- Moved PORT definitions to intel_bios.h and renamed as DVO_PORT_MIPIA
- renamed is_mipi to has_mipi and moved definition as suggested

Looking at our current dsi driver I note that:
- We don't have any slave driver right now.
- There's zero support for the hardware state readout and cross check
code.
- All the modeset state seems to be tracked in the intel_dsi structure
instead of the pipe config.
Given all that I can't properly audit the dsi ->mode_set callback. So
just do it as the first thing in the ->pre_pll_enable hook and hope
for the best.

Currently we allow encoders to indicate whether they can be part of a
cloned set with just one flag. That's not flexible enough to describe
the actual hardware capabilities. Instead make it a bitmask of encoder
types with which the current encoder can be cloned.
For now we set the bitmask to allow DVO+DVO and DVO+VGA, which should
match what the old boolean flag allowed. We will add some more cloning
options in the future.
Note that this patch also removes the encoder.possible_clones setting
from encoder setup code - we compute this dynamically.

Since the encoder is tied to its port, we need to make sure the power
domain for that port is on before reading out the encoder HW state.

handler, which checks - after this change - for all power domains
the connector needs.

Since
commit d9255d57147e1dbcebdf6670409c2fa0ac3609e6
Author: Paulo Zanoni <paulo.r.zanoni@intel.com>
Date: Thu Sep 26 20:05:59 2013 -0300
it became clear that we need to separate the unload sequence into two
parts:
1. remove all interfaces through which new operations on some object
(crtc, encoder, connector) can be started and make sure all pending
operations are completed
2. do the actual tear down of the internal representation of the above
objects
The above commit achieved this separation for connectors by splitting
out the sysfs removal part from the connector's destroy callback and
doing this removal before calling drm_mode_config_cleanup() which does
the actual tear-down of all the drm objects.
Since we'll have to customize the interface removal part for different
types of connectors in the upcoming patches, add a new unregister
callback and move the interface removal part to it.
No functional change.

Basically ULPS handling during enable/disable has been moved to
pre_enable and post_disable phases. PLL and panel power disable
also has been moved to post_disable phase. The ULPS entry/exit
sequneces as suggested by HW team is as follows -
During enable time -
set DEVICE_READY --> Clear DEVICE_READY --> set DEVICE_READY
And during disable time to flush all FIFOs -
set ENTER_SLEEP --> EXIT_SLEEP --> ENTER_SLEEP
Also during disbale sequnece sub-encoder disable is moved to the end
after port is disabled.

For some reason, every single time I try to run module_reload
something tries to read the connector sysfs files. This happens
after we destroy the encoders and before we destroy the connectors, so
when the sysfs read triggers the connector detect() function,
intel_conector->encoder points to memory that was already freed.
The bad backtrace is just:
[<ffffffff8163ca9a>] dump_stack+0x54/0x74
[<ffffffffa00c2c8e>] intel_dp_detect+0x1e/0x4b0 [i915]
[<ffffffffa001913d>] status_show+0x3d/0x80 [drm]
[<ffffffff813d5340>] dev_attr_show+0x20/0x60

[<ffffffff81221f79>] sysfs_read_file+0xa9/0x1b0
[<ffffffff811aaf1e>] vfs_read+0x9e/0x170
[<ffffffff811aba4c>] SyS_read+0x4c/0xa0
[<ffffffff8164e392>] system_call_fastpath+0x16/0x1b
But if you add tons of memory checking debug options to your Kernel
you'll also see:
- general protection fault: 0000
- BUG kmalloc-4096 (Tainted: G D W ): Poison overwritten
- INFO: Allocated in intel_ddi_init+0x65/0x270 [i915]
- INFO: Freed in intel_dp_encoder_destroy+0x69/0xb0 [i915]
Among a bunch of other error messages.
So this commit just destroys the sysfs files before both the encoder
and connectors are freed.
