Bit operation for fsi_master should be done inside master lock. But soft-reset/interrupt operation were outside of it. This patch modify this problem. It still allow to INT_ST outside-operation on fsi_interrupt, but it is not problem. Because this register doesn't need the bit operation. Signed-off-by:

In current FSI driver, playback function cares only overrun, and capture function cares only underrun. But playback function should had cared about underrun, and capture function should had cared about overrun too. Signed-off-by:

ctrl_outl() has become void at some point, which breaks compilation of fsi.c. Make writing functions void, as their output is anyway not evaluated, and use __raw_writel and __raw_readl instead of deprecated ctrl_outl and ctrl_inl respectively. Signed-off-by:

fsi_master_xxx function should be protected by spin lock, because it are used from both FSI-A and FSI-B. Signed-off-by:

platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use (int)irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228 that changed the return value of platform_get_irq from 0 to -ENXIO on error. Signed-off-by:

Current FSI driver use global variable to access device data. But this style will be broken if SuperH come with multiple FSI blocks in future. To solve this problem, this patch use cpu_dai->private_data. Signed-off-by:

This patch add support runtime PM. Driver callbacks for Runtime PM are empty because the device registers are always re-initialized after pm_runtime_get_sync(). The Runtime PM functions replaces the clock framework module stop bit handling in this driver. Signed-off-by:

SuperH FSI device have the hardware limitation to use DMA. If DMA is used, LCD output will be broken. Maybe there are some solution. But I don't know how to do it now. This patch remove DMA support and use soft transfer. Signed-off-by:
