* ASoC: fsi: Modify over/under run error settlementKuninori Morimoto2010-02-23
| | | | | | | | | | | | 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.

* ASoC: fix compilation breakage in sound/soc/sh/fsi.cGuennadi Liakhovetski2010-02-03
| | | | | | | | | | | 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.

* ASoC: fsi: Add spin lock operation for accessing shared areaKuninori Morimoto2010-01-28
| | | | | | | | | fsi_master_xxx function should be protected by spin lock, because it are used from both FSI-A and FSI-B. Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| * ASoC: sh: FSI:: don't check platform_get_irq's return value against zeroUwe Kleine-König2009-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

* | ASoC: sh_fsi: avoid using global variableKuninori Morimoto2009-12-03
|/ | | | | | | | | | | 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.

* ASoC: sh: fsi: Add runtime PM supportKuninori Morimoto2009-11-30
| | | | | | | | | | | | | 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.

* ASoC: sh: FSI: Remove DMA supportKuninori Morimoto2009-10-30
| | | | | | | | | | 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: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
