* sparc,leon: Convert to use devm_ioremap_resourceTushar Behera2013-06-19
| | | | | | | | | | | | | | Commit 75096579c3ac ("lib: devres: Introduce devm_ioremap_resource()") introduced devm_ioremap_resource() and deprecated the use of devm_request_and_ioremap(). While at it, also remove the error message as devm_ioremap_resource() also prints similar error message.

* sparc32, leon: Enable interrupts before going idle to avoid getting stuckAndreas Larsson2013-06-19
| | | | | | | | | | | | This enables interrupts for Leon before having the CPU enter power-down mode. Commit 87fa05aeb3a5e8e21b1a5510eef6983650eff092, "sparc: Use generic idle loop", gets the CPU stuck on idle for Leon systems. On Leon, disabling interrupts and powering down the processor will get the processor stuck waiting for an interrupt that will never be reacted to.

* sparc32, leon: Remove separate "ticker" timer for SMPAndreas Larsson2013-06-19
| | | | | | | | | | | | | This reduces the need from two timers to one timer. Moreover, without this patch, when the "ticker" timer triggers timer_cs_read via tick_periodic it reads the value of the usual timer it can get an wrapped timer value without timer_cs_internal_counter having been updated leading to the clock going backwards. This effectively hangs one cpu that gets stuck in update_wall_time with an offset slightly smaller than 0xffffffffffffffff.

However, the accessory interface itself, if also enabled, already is at index 0 and shifts the actual audio interface numbers to 1 and 2, which prevents the PCM streaming interface from being seen by the host driver. To get the PCM interface interface to work, detect when the descriptors point to the (for this driver useless) accessory interface, and redirect to the correct one.

The bugzilla bug report is here: https://bugzilla.kernel.org/show_bug.cgi?id=56271 The cause is that the wm8775 is optional, so even though the board info says there is one, it doesn't have to be there. Checking whether the module was actually loaded is much safer. Note that this driver is quite buggy when it comes to unloading and reloading modules. Unloading cx8800 and reloading it again will still cause a crash, most likely because either the i2c bus isn't unloaded at the right time and/or the v4l2_device_unregister isn't called at the right time.

The clock framework doesn't guarantee a clock will not get enabled during e.g. clk_set_parent if clk_prepare has been called on it. So we ensure clk_prepare() is called only when it is safe to enable the clocks, i.e. the parent clocks and the clocks' frequencies are set. It must be ensured the FIMC-IS clocks have proper frequencies before they are enabled, otherwise the whole system will hang.

The driver was doing just a clk_prepare on this special clock without a clk_enable call. As this sclk is the parent of gate clock, it gets prepared and enabled along with the gate clock. So there is no need for the driver to use this sclk. This patch removes the sclk usage from driver.
