This series contains all the changes necessary to make SATA work on the da850-lcdk board. The first patch adds DT bindings for the ahci-da850 driver. The second enables relevant modules in davinci_all_defconfig. Patches 03/14-06/14 modify the way the clocks are handled regarding SATA on the da850 platform. We modify the ahci driver to retrieve the clock via con_id and model the external SATA oscillator as a real clock. Patches 07/14-11/14 extend the ahci-da850 driver. Add DT support, implement workarounds necessary to make SATA work on the da850-lcdk board and un-hardcode the external clock multiplier. Last two patches add device tree changes required to probe the driver. v1 -> v2: - dropped patch 04/10 - replaced with local changes in the ahci-da850 driver - added comments explaining the workaround in ahci softreset - s/0x218000/218000 in the sata DT node label - added patches chaning the way clocks are handled in the da850 SATA code both in arch/ and in the ahci driver - dropped the clock multiplier property in the DT bindings in favor of using struct clk to pass the refclk rate to the driver - minor tweaks in commit messages v2 -> v3: - dropped the clocks property from the ahci-da850 DT binding - dropped patch 12/14 (SATA pinmux settings) - dropped an outdated fragment from the commit message in patch 14/14 - s/get_clk()/clk_get()/ - s/connector id/connection id/ - stopped using __div64_32() after noticing that it sometimes produces invalid results - removed the default MPY value from ahci-da850 - registered SATA refclk for board file boot mode as well Bartosz Golaszewski (13): devicetree: bindings: add bindings for ahci-da850 ARM: davinci_all_defconfig: enable SATA modules ARM: davinci: add a clock lookup entry for the SATA clock sata: ahci-da850: get the sata clock using a connection id ARM: davinci: da850: add con_id for the SATA clock ARM: davinci: da850: model the SATA refclk sata: ahci-da850: add device tree match table sata: ahci-da850: implement a workaround for the softreset quirk sata: ahci: export ahci_do_hardreset() locally sata: ahci-da850: add a workaround for controller instability sata: ahci-da850: un-hardcode the MPY bits ARM: dts: da850: add the SATA node ARM: dts: da850-lcdk: enable the SATA node .../devicetree/bindings/ata/ahci-da850.txt | 15 ++ arch/arm/boot/dts/da850-lcdk.dts | 4 + arch/arm/boot/dts/da850.dtsi | 6 + arch/arm/configs/davinci_all_defconfig | 2 + arch/arm/mach-davinci/da850.c | 2 +- arch/arm/mach-davinci/da8xx-dt.c | 9 ++ arch/arm/mach-davinci/devices-da8xx.c | 29 ++++ arch/arm/mach-davinci/include/mach/da8xx.h | 1 + drivers/ata/ahci.h | 3 + drivers/ata/ahci_da850.c | 175 +++++++++++++++++++-- drivers/ata/libahci.c | 18 ++- 11 files changed, 241 insertions(+), 23 deletions(-) create mode 100644 Documentation/devicetree/bindings/ata/ahci-da850.txt -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
