2015-12-08ARM: shmobile: r8a7778: tidyup #sound-dai-cells settingsKuninori Morimoto1-1/+6
Renesas sound driver needs #sound-dai-cells settings, but, this usage is a little bit confusable. It came from ALSA SoC historical reasons. The sound DAI naming method is different between Single/Multi DAI in the ALSA framework, and it is used for sound card matching. And this #sound-dai-cells has relationship to it. Current SoC dtsi has #sound-dai-cells = <1> as default settings (= it is assuming that board/platform has multi DAI), and board/platform side needs to overwrite it if board/platform was single DAI. This style is more confusable for users. This patch removes SoC side default settings, and force to set it by board/platform side.

The default value of #sound-dai-cells in r8a7778.dtsi is one, while the /sound/simple-audio-card,cpu device node in r8a7778-bockw.dts uses a phandle without any extra cells ("<&rcar_sound>"), causing: /sound/simple-audio-card,cpu: arguments longer than property asoc-simple-card sound: parse error -22 asoc-simple-card: probe of sound failed with error -22 Override #sound-dai-cells to zero to fix this.

22b160713cb6 ("ARM: shmobile: alt: Add pfc pins to DT") introduced pfc pins to the alt device tree but did not reference them. This patch fixes ether pfc by: * Referencing ether pins * Adding and referencing phy1 pins * Removing ether b pins.

2015-11-17ARM: shmobile: r8a7794: Use SoC specific binding for rcar-dmac nodesSimon Horman1-2/+2
Use the new SoC specific binding for rcar-dmac and the generic binding as a fall-back in the r8a7794 device tree. In general Renesas hardware is not documented to the extent where the relationship between IP blocks on different SoCs can be assumed although they may appear to operate the same way. Furthermore the documentation typically does not specify a version for individual IP blocks. For these reasons a convention of using the SoC name in place of a version and providing SoC-specific compat strings has been adopted. Although not universally liked this convention is used in the bindings for most drivers for Renesas hardware. The purpose of this patch is to update the Renesas R-Car DMA Controller nodes to follow this convention. Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

(and it worked so far as we never saw a Bus error from userspace until IPPK guys tested a DDR controller with ECC error detection etc hence needed to explicitly trigger/handle such errors) - So move mem_service exception handler from common code into ARCv2 code. - In ARCompact code, define mem_service as L2 interrupt handler which just drops down to pure kernel mode and goes of to enqueue SIGBUS Reported-by: Nelson Pereira <npereira@synopsys.com> Tested-by: Ana Martins <amartins@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
