OMAPDSS: HDMI: Add M2 divider while calculating clkout
While calculating regm and regmf value add using M2 divider in
the equation.
Formula for calculating:
Output clock on digital core domain:
CLKOUT = (M / (N+1))*CLKINP*(1/M2)
Internal oscillator output clock on internal LDO domain:
CLKDCOLDO = (M / (N+1))*CLKINP
The current code when allows variable M2 values as input
ignores using M2 divider values in calculation of regm and regmf.
so fix it by using M2 in calculation although the default value for
M2 is 1.

OMAPDSS: HACK: Ensure DSS clock domain gets out of idle when HDMI is enabled
For DSS clock domain to transition from idle to active state. It's necessary
to enable the optional clock DSS_FCLK before we enable the module using the
MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register.
This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led
to DSS clock domain not getting out of idle when pm_runtime_get_sync() was
called for hdmi's platform device.
Since the clock domain failed to change it's state to active, the hwmod code
disables any clocks it had enabled before for this hwmod. This led to the clock
'dss_48mhz_clk' gettind disabled.
When hdmi's runtime_resume() op is called, the call to dss_runtime_get()
correctly enables the DSS clock domain this time. However, the clock
'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was
disabled previously, the driver fails when it tries to enable HDMI's PHY.
Fix this for now by ensuring that dss_runtime_get() is called before we call
pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would
be to modify the DSS related hwmod's mainclks, and also some changes in how
opt clocks are handled in the DSS driver.
This fixes the issue of HDMI not working when it's the default display. The
issue is not seen if any other display is already enabled as the first display
would have correctly enabled the DSS clockdomain.

OMAPDSS: HDMI: PHY burnout fix
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.
This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.
The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.
The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

OMAPDSS: use sync versions of pm_runtime_put
omapdss doesn't work properly on system suspend. The problem seems to be
the fact that omapdss uses pm_runtime_put() functions when turning off
the hardware, and when system suspend is in process only sync versions
are allowed.
Using non-sync versions normally and sync versions when suspending would
need rather ugly hacks to convey the information of
suspending/not-suspending to different functions. Optimally the driver
wouldn't even need to care about this, and the PM layer would handle
syncing when suspend is in process.
This patch changes all omapdss's pm_runtime_put calls to
pm_runtime_put_sync. This fixes the suspend problem, and probably the
performance penalty of always using sync versions is negligible.

OMAP: DSS2: HDMI: improve hdmi output enable
Enabling HDMI output often causes sync lost errors, and almost always
causes timeout errors being printed from dispc_mgr_enable_digit_out().
The sync lost problem seems to go lessen greatly if we first enable the
HDMI output, and only then enable the DISPC output. However, as this is
only based on observations, the fix may not be perfect as the problem
may lie somewhere else. Nevertheless, HDMI works better with this patch.
This will also fix the dispc's dispc_mgr_enable_digit_out(), as the code
waits for two VSYNCs after enabling the output. If the HDMI output is
disabled (as it was previously), there are no VSYNCs and
dispc_mgr_enable_digit_out() will print timeout errors.

HDMI IP fundamentally has replaceable core PHY and PLL blocks.
These blocks might vary across OMAP's but the end functionality such as to

Thus to make the current hdmi DSS driver compatible with different OMAP's having
different IP blocks( A combination of different core, PHY, PLL blocks), function
pointer approach is introduced.
With function pointer, relevant IP dependent functions are mapped to the generic
functions used by DSS during the initialization based on the OMAP compiled.
Thus making hdmi DSS driver IP agnostic.

- Remove "channel" from the name, e.g. dispc_enable_channel ->
dispc_mgr_enable
The idea is to group manager related functions so that it can be deduced
from the function name that it writes to manager spesific registers.
All dispc_mgr_* functions have enum omap_channel as the first parameter.

OMAP: DSS2: remove unneeded fck enable/disables
Now that the HWMOD fmwk handles the fcks of DSS modules properly, the
DSS driver no longer needs to explicitely enable/disable the fck.
This patch removes the enables/disables of fck from dispc, dsi and dss.
The clk_get(fck) is still needed there, as the modules need to know the
frequency of the clock.
For hdmi and venc this patch also removes the clk_get(fck), as they
don't need the clock at all.

OMAP: DSS2: check for manager when enabling display
None of the DSS interface drivers check if an overlay manager is
connected to the display when the display is being enabled. This leads
to null pointer crash if the display has no manager.
This patch checks for the manager and returns an error if it is null.

OMAP: DSS2: HDMI: fix hdmi clock name
The HDMI clock (hdmi_clk) is missing in the current OMAP4 HWMOD
database. Fix this in the DSS driver by using the old clock name
(dss_48mhz_clk).

OMAP: DSS2: Use PM runtime & HWMOD support
Use PM runtime and HWMOD support to handle enabling and disabling of DSS
modules.
Each DSS module will have get and put functions which can be used to
enable and disable that module. The functions use pm_runtime and hwmod
opt-clocks to enable the hardware.

OMAP4: DSS2: HDMI: Implement ASoC Codec driver for HDMI audio
Implement an ASoC Codec Driver to handle audio configuration. The
implementation offers an interface for audio configuration and
control to be exposed to ALSA while hidding the HDMI details.
The ASoC driver supports the Basic Audio configuration as described
in CEA-861-D: 2-channel linear PCM with 32, 44.1 and 48kHz sample
rates and 16 bits/sample. It additionally supports 24 bit/sample
in 32-bit words.
