[PATCH 0/3] omap: n8x0: Audio update to N810

[PATCH 0/3] omap: n8x0: Audio update to N810

[Jarkko Nikula]

Hi

With this set and a fix [1] it is possible to get ALSA SoC on N810 working.

This set is generated against mainline commit e320cea but applies also to
linux-omap (board-n8x0.c has cbus patches in linux-omap).

[PATCH 1/3] omap: n8x0: Cleanup i2c1 and menelaus registration

[Jarkko Nikula]

- Move n8x0_i2c_board_info_1 out from #ifdef CONFIG_MENELAUS block,
  register i2c1 in n8x0_init_machine and do a few clean-ups around these.
  Code looks better if board infos are grouped together
- Mark n8x0_i2c_board_info_1 and n8x0_menelaus_platform_data with __initdata

[PATCH 2/3] omap: n8x0: Register i2c2 and add board info with tlv320aic3x for N810

[Jarkko Nikula]

Second i2c bus on Nokia N800 and N810 shares both common and hw specific
peripherals. Register now this bus and add board info with tlv320aic3x for
N810. Common peripherals may be added as an additional board info to
omap_register_i2c_bus(2, ...);

With this patch it is possible to probe tlv320aic3x audio codec and get the
ASoC subsystem registered on Nokia N810.

[PATCH 3/3] omap: n8x0: Mux i2s codec port pins for McBSP block

[Jarkko Nikula]

Bootloader on Nokia N800 and N810 muxes I2C codec port pins for EAC block.
As there is no driver and use for EAC, mux those pins for McBSP instead
since N810 ASoC drivers can use it.

I've added these into omap for-next for 2.6.37. Let me know if these should
go in along with other ASoC patches.

Ok, good. This is independent set so no need for any special
procedure :-)
