DSS enables core clocks for the duration of initialization to avoid unnecessary context saves and restores. With PM runtime the clocks cannot be handled in this way, outside the dss module drivers. Thus we need to remove the optimization. Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

The initialization order of the DSS modules is important when pm_runtime support is implemented. Currently RFBI is initialized before DISPC, which will cause problems with pm_runtime as RFBI uses DISPC. The same goes for uninitialization order, and dss_uninit needs to be called last, and dispc_uninit just before that. Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

The DMA FIFO threshold registers and burst size registers have changed for OMAP4. The current code only handles OMAP2/3 case, and so the values are a bit off for OMAP4. A summary of the differences between OMAP2/3 and OMAP4: Burst size: OMAP2/3: 4 x 32 bits / 8 x 32 bits / 16 x 32 bits OMAP4: 2 x 128 bits / 4 x 128 bits / 8 x 128 bits Threshold size: OMAP2/3: in bytes (8 bit units) OMAP4: in 128bit units This patch fixes the issue by creating two new helper functions in dss_features: dss_feat_get_buffer_size_unit() and dss_feat_get_burst_size_unit(). These return (in bytes) the unit size for threshold registers and unit size for burst size register, respectively, and are used to calculate correct values. For the threshold size the usage is straightforward. However, the burst size register has different multipliers for OMAP2/3 and OMAP4. This patch solves the problem by defining the multipliers for the burst size as 2x, 4x and 8x, which fit fine for the OMAP4 burst size definition (i.e. burst size unit for OMAP4 is 128bits), but requires a slight twist on OMAP2/3 by defining the burst size unit as 64bit. As the driver in practice always uses the maximum burst size, and no use case currently exists where we would want to use a smaller burst size, this patch changes the driver to hardcode the burst size when initializing DISPC. This makes the threshold configuration code somewhat simpler. Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

When the panel driver calls omapdss_dsi_display_disable() it is possible that there are still some unsent packets in the TX fifo. Add dsi_sync_vc() calls in the beginning of omapdss_dsi_display_disable() to make sure the TX fifos are empty. This allows us to remove the msleep(10) hack from panel-taal.c Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

OMAP3430 requires an 96MHz clock to VENC's DAC, but no other OMAP needs it.

LANEx_ULPS_SIG2 bits are left on after entering ULPS. This doesn't cause any problems currently, as DSI HW is reset when it is enabled. However, if the reset is not done, operation fails if the bits are still set. So reset the bits after entering ULPS to ensure operation even without HW reset.

If ULPS exit fails, and the following reset fails also, Taal driver was left in state where it thinks DSI is enabled while it really isn't, leading to crash. This patch checks the return value of taal_panel_reset, and if that fails, ulps_enabled is left true, causing the driver to retry ulps exit later. Also the return value of taal_wake_up is checked at taal_disable, and if wake up fails, we'll skip the power_off. This could leave the panel into a not-quite-valid state, but there's nothing we can do about it in that situation. Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

Implement auto-update mode for manual-update displays. omapfb driver uses a delayed work to update the display with a constant rate. The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which previously called omapdss but is now handled inside omapfb, and a new sysfs file, "update_mode". The update interval is by default 20 times per second, but can be changed via "auto_update_freq" module parameter. There is also a new module parameter "auto_update", which will make omapfb start manual update displays in auto-update mode. This auto-update mode can be used for testing if the userspace does not support manual update displays properly. However, it is a very inefficient solution, and should be considered more as a hack for testing than something that could be used as a long term solution.

Commit 13e12d14 ("vfs: reorganize 'struct inode' layout a bit") moved things around a bit changed i_state to be unsigned int instead of unsigned long. That was to help structure layout for the 64-bit case, and shrink 'struct inode' a bit (admittedly that only happened when spinlock debugging was on and i_flags didn't pack with i_lock). However, Meelis Roos reports that this results in unaligned exceptions on sprc, and it turns out that the bit-locking primitives that we use for the I_NEW bit want to use the bitops. Which want 'unsigned long', not 'unsigned int'. We really should fix the bit locking code to not have that kind of requirement, but that's a much bigger change. So for now, revert that field back to 'unsigned long' (but keep the other re-ordering changes from the commit that caused this). Andi points out that we have played games with this in 'struct page', so it's solvable with other hacks too, but since right now the struct inode size advantage only happens with some rare config options, it's not worth fighting. It _would_ be worth fixing the bitlocking code, though. Especially since there is no type safety in the bitlocking code (this never caused any warnings, and worked fine on x86-64, because the bitlocks take a 'void *' and x86-64 doesn't care that deeply about alignment). So it's currently a very easy problem to trigger by mistake and never notice.
