* OMAPDSS: fix shared irq handlersTomi Valkeinen2014-04-142-7/+68
| | | | | | | | | | | | | | | | | | | | | | DSS uses shared irq handlers for DISPC and DSI, because on OMAP3, the DISPC and DSI share the same irq line. However, the irq handlers presume that the hardware is enabled, which, in theory, may not be the case with shared irq handlers. So if an interrupt happens while the DISPC/DSI is off, the kernel will halt as the irq handler tries to access the DISPC/DSI registers. In practice that should never happen, as both DSI and DISPC are in the same power domain. So if there's an IRQ for one of them, the other is also enabled. However, if CONFIG_DEBUG_SHIRQ is enabled, the kernel will generate a spurious IRQ, which then causes the problem. This patch adds an is_enabled field for both DISPC and DSI, which is used to track if the HW is enabled. For DISPC the code is slightly more complex, as the users of DISPC can register the interrupt handler, and we want to hide the is_enabled handling from the users of DISPC.

* OMAPDSS: fix rounding when calculating fclk rateTomi Valkeinen2014-04-141-2/+2
| | | | | | | | | | | | | "clk: divider: fix rate calculation for fractional rates" patch (and similar for TI specific divider) fixes the clk-divider's rounding. This patch updates the DSS driver to round the rates accordingly. This fixes the DSS's warnings about clock rate mismatch, and also fixes the wrong fclk rate being set.

The non-DT code will be removed after all boards have been converted to DT, so there's no need to change the non-DT code to act the same way. The code for DPI and SDI needs to be refined later to make it possible to add multiple DPI ports. For now, handling just a single DPI port is enough for all the boards.

| * | fbdev: vesafb: add dev->remove() callbackDavid Herrmann2014-03-071-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If x86-sysfb platform-devices are removed from a system, we should properly unload vesafb. Otherwise, we end up releasing the parent while our vesa framebuffer is still running. This currently works just fine, but will cause problems on handover to real hw. So add the ->remove() callback and unregister vesafb. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is necessary in order to make the core set file->private_data to miscdev in use. We need that information later to dereference the container of the device, so we can get access to our private struct from other callbacks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of passing around struct platform_device, use struct device. That saves one level of dereference. Also, call platform devices pdev, and provide a shortcut for &pdev->dev.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because uvesafb_vbe_init will fail when get zero avaiable modes, and we have checked the return value of uvesafb_vbe_init_mode, so it is impossible to pass NULL as mode into uvesafb_init_info.
