Patch set 12 of 12 The current sdhci-pxa code is only useful for MMP2. It does not work on other PXA controllers. Factor out the common code and define 3 SoC specific files that control the SD hardware. Take into account that while the PXA910 and PXA168 controllers are similar they have different quirks due to hardware differences. MMP2 is different since it is based on the SD 3.0 controller spec while the other 2 SoC are based on SD 2.0 spec with SoC specific extensions. [PATCH] sdhci: Add support PXA168, PXA910, and MMP2 controllers Select pxa controller based on CPU model: MMP2, PXA168, PXA910 Three new SoC specific files added: sdhci-pxa168.c sdhci-pxa910.c sdhci-mmp2.c These files control the platform specific behavior of the SD controller. MMP2 and the PXAxxx controllers use different hardware registers to control platform specific behavior. Platform flags come from arch/mach-mmp/ files for board design (brownstone, jasper, aspenite etc) settings (8 bit capable slot / card permanent). quirks for SD/SoC specific behaviro defined in specific platform files (sdhci-pxa168.c, sdhci-pxa910.c, sdhci-mmp2.c) The correct SD controller is now shown Kconfig. sdhci-pxa.c changed to act as a shim for the platform specific code. Only generic operations are handled in sdhci-pxa.c. All platform operations are passed to the platform code. reset_enter() and reset_exit() used for silicon control. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
