+Subject: [PATCH] ahci_imx: add ahci sata support on imx platforms
+
+imx6q contains one Synopsys AHCI SATA controller, But it can't share
+ahci_platform driver with other controllers because there are some
+misalignments of the generic AHCI controller - the bits definitions of
+the HBA registers, the Vendor Specific registers, the AHCI PHY clock
+and the AHCI signals adjustment window(GPR13 register).
+
+ - CAP_SSS(bit20) of the HOST_CAP is writable, default value is '0',
+ should be configured to be '1'
+
+ - bit0 (only one AHCI SATA port on imx6q) of the HOST_PORTS_IMPL
+ should be set to be '1'.(default 0)
+
+ - One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be
+ configured regarding to the frequency of AHB bus clock.
+
+ - Configurations of the AHCI PHY clock, and the signal parameters of
+ the GPR13
+
+Setup its own ahci sata driver, contained the imx6q specific
+initialized codes, re-use the generic ahci_platform driver, and keep
+the generic ahci_platform driver clean as much as possible.

+Subject: [PATCH] ahci_imx: depend on CONFIG_MFD_SYSCON
+
+ahci_imx makes use of regmap but the dependency wasn't specified in
+Kconfig leading build failures if CONFIG_AHCI_IMX is enabled but
+CONFIG_MFD_SYSCON is not. Add the Kconfig dependency.
