This adds initial support for requesting the various GPIO functions
necessary for certain ports. This just plugs in dumb request/free logic,

There are two issues in vmw_kms_update_layout_ioctl(). First, the
for loop forgets to index rects and only checks the first element.
Second, there is a potential integer overflow if userspace passes
in a large arg->num_outputs. The call to kzalloc() would allocate
a small buffer, leading to out-of-bounds read.

Disabling the CRTC by setting its framebuffer to NULL, as used by
drm_framebuffer_cleanup(), was failing to pass the current framebuffer
to the crtc_func->disable callback. This is because of the dance within
drm_crtc_helper_set_config to pass the new_fb (NULL in this case) to the
drm_crtc_helper_set_mode with the currently attached fb as a parameter.
drm_crtc_helper_set_mode treats this as a no-op and the encoder is still
enabled. And so the current fb is forgotten before the call to
drm_helper_disable_unused_functions.
This patch treats disabling the CRTC as a simple special case rather
than adding further complexity into the configuration logic.
This fixes a pin-leak of the fb bo on Xserver close.

When toggling the MCE support we don't want to concern ourselves with the
FIFO state, so ensure that the clearing bits are masked out when updating
the MCE state.
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
The bulk of the ports do not support any sort of modem control, so
blindly twiddling the MCE bit doesn't accomplish much. We now require
ports to manually specify which line supports modem control signals.
While at it, tidy up the RTS/CTSIO handling in SCSPTR parts so it's a bit
more obvious what's going on (and without clobbering other configurations
in the process).

Current code will always write fifo threshold values to the register,

Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
Currently fifo threshold configuration is done per overlay or per
manager. However, when a fifo size configuration is added, we need to
always configure the thresholds for all overlays.
This patch prepares for that by changing the fifo threshold
configuration to always handle all overlays.
Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
When we are enabling an overlay, there's a point in time when the
overlay is not actually enabled yet (nor do we want it to be enabled),
but we do want to check if the configuration for the overlay is valid,
and to calculate correct fifo thresholds for the soon-to-be-enabled
overlay.
Current code handled this in a hacky way, setting op->enabled to true
temporarily when calling functions that need to consider the state when
the overlay is enabled.
This patch makes this a bit cleaner, adding "enabling" field, which is
set when the overlay is not yet enabled but should be considered in the
checks and calculations.

Currently dss_write_regs() implicitely sets the GO bits for all managers
with shadow dirty flags set. This is a bit misleading, as one does not
presume "write registers" function to also set the GO bit.
Thus this patch splits the setting of GO bits into a separate function,
dss_set_go_bits, which is used after writing the registers.
Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
In the apply irq handler the code currently clears the shadow dirty
flags whenever the manager in question is not busy (i.e. GO bit is
down). However, this is not quite right, as the GO bit may have never
been set.
While not done in the current code, the above would cause bug in
scenario where the registers are written, and thus shadow_dirty flag is
set, but the GO bit will be set only later. In this case the
shadow_dirty flags would be cleared, even if the HW is not using the new
configurations.
This patch fixes the issue by clearing the shadow flags only when the GO
bit is clear, and the GO bit had been set.

need_isr() should return true whenever there's work that needs to be
handled in the VSYNC/FRAMEDONE irq handler. However, need_isr() is

This patch adds checks for shadow dirty flags, so that the irq handler
is started/kept running while shadow dirty flags are set.

extra_info_update_ongoing() skipped checks for overlays that were marked
as disabled. This doesn't work, as the enable status of an overlay is in
the extra_info group, and thus extra_info_update_ongoing() reports false
when we are disabling an overlay. This causes
wait_pending_extra_info_updates() to not wait for the ongoing overlay
disable.
This patch changes extra_info_update_ongoing() to check the state of
overlays marked as disabled.
