V4: add imx6q specific ahci sata support Thanks for the review comments provided by Sascha, and Alexander. - Use the private data and keep a pointer to the PHY clock. - Don't use the global platform device variable, because that it would make the driver broken for mutiple instances. - Don't do the "writel" with assignment. - Other minor changes, such as print the error code when printing error message, use a u32 type to store readl results, and so on. v3: http://www.spinics.net/lists/linux-ide/msg45688.html - Keep arch/arm and ahci_platform driver clean. - Add the sata_imx standalone driver contained all the specific setup - Add the release function, support the loadable module driver. - Tested on imx6q sd board. v2: http://www.spinics.net/lists/linux-ide/msg45666.html - Setup standalone imx ahci sata driver, because of the misalignments of the bits definition of the HBA register. - Replace the node by the label in the board dts. - v1: http://www.spinics.net/lists/linux-ide/msg45581.html - add imx6q specific ahci sata support to arch/arm/mach-imx/mach-imx6q.c These patches is based on imx/dt branch of "http://git.linaro.org/git-ro/people/shawnguo/linux-2.6.git"; [v4 1/3] ARM: dtsi: enable ahci sata on imx6q platforms [v4 2/3] ARM: imx6q: update the sata bits definitions of gpr13 [v4 3/3] sata: imx: add ahci sata support on imx platforms arch/arm/boot/dts/imx6q-sabreauto.dts | 4 + arch/arm/boot/dts/imx6q-sabrelite.dts | 4 + arch/arm/boot/dts/imx6q-sabresd.dts | 4 + arch/arm/boot/dts/imx6q.dtsi | 9 + drivers/ata/Kconfig | 9 + drivers/ata/Makefile | 1 + drivers/ata/sata_imx.c | 237 +++++++++++++++++++++++++++ include/linux/mfd/syscon/imx6q-iomuxc-gpr.h | 121 ++++++++++---- 8 files changed, 352 insertions(+), 37 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
