From: Bintian Wang <wangbintian@xxxxxxxxx> Hi6220 is one mobile solution of Hisilicon, this patchset contains initial support for Hi6220 SoC and HiKey development board, which supports octal ARM Cortex A53 cores. Initial support is minimal and includes just the arch configuration, clock driver, device tree configuration. PSCI is enabled in device tree and there is no problem to boot all the octal cores, and the CPU hotplug is also working now, you can download and compile the latest firmware based on the following link to run this patch set: https://github.com/96boards/documentation/wiki/UEFI Changes v6~v8: This three versions only modified the clock drivers based on the Stephen's review advices. * clk-hi6220.c: ** Split the clock header file from clock driver ** Delete setting the parents clock of UART1 to HI6220_150M in clock driver, we can do that using assigned-clock in dts when enable UART1 in the future. * clkdivider-hi6220.c: ** Reuse some functions exported by clk-divider.c ** Remove "pr_err" and CLK_IS_BASIC flag ** Fix some programing style problems * hisilicon/clk.h: remove the "__init" markings on some funcition prototypes. Changes v5: * Rebase to kernel 4.1-rc2 * Add compatible string "hisilicon,hi6220-pl011" for Hisilicon designed UART * clk-hi6220.c: use __initdata for non-const arrays based on the commit 692d8328e8c039f9497eb862c6cf835de922c061 Changes v4: * Rebase to kernel 4.1-rc1 * Delete "arm,cortex-a15-gic" from the gic node in dts Changes v3: * Verified the CPU hotplug based on the new released firmware * Redefined the compatible strings of four system controllers in dts * Setting COMMON_CLK_HI6220 to a bool symbol * Keep CONFGI_ARCH_HISI sorted alphabetically Changes v2: * Split the DT bindings documents into earlier patches * Change SMP enable method from spin-table to PSCI in device tree * Remove "clock-frequency" from armv8-timer device node in device tree * Add more description about Hisilicon designed system controllers in DT bindings document * Enable high speed clock on UART1 mux * Other changes based on the discussion in the mailing list: https://lkml.org/lkml/2015/2/5/147 Bintian Wang (7): arm64: hi6220: Document devicetree bindings for Hisilicon hi6220 SoC clk: hi6220: Document devicetree bindings for hi6220 clock Documentation: DT: PL011: hi6220: add compatible string for Hisilicon designed UART clk: hisilicon: Remove __init for marking function prototypes dt-bindings: Add header file of hi6220 clock driver clk: hi6220: Clock driver support for Hisilicon hi6220 SoC arm64: dts: Add dts files for Hisilicon Hi6220 SoC .../bindings/arm/hisilicon/hisilicon.txt | 87 +++++++ .../devicetree/bindings/clock/hi6220-clock.txt | 34 +++ Documentation/devicetree/bindings/serial/pl011.txt | 4 +- arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/hisilicon/Makefile | 5 + arch/arm64/boot/dts/hisilicon/hi6220-hikey.dts | 31 +++ arch/arm64/boot/dts/hisilicon/hi6220.dtsi | 172 +++++++++++++ drivers/clk/Kconfig | 1 + drivers/clk/Makefile | 4 +- drivers/clk/hisilicon/Kconfig | 6 + drivers/clk/hisilicon/Makefile | 3 +- drivers/clk/hisilicon/clk-hi6220.c | 284 +++++++++++++++++++++ drivers/clk/hisilicon/clk.c | 29 +++ drivers/clk/hisilicon/clk.h | 39 ++- drivers/clk/hisilicon/clkdivider-hi6220.c | 156 +++++++++++ include/dt-bindings/clock/hi6220-clock.h | 173 +++++++++++++ 16 files changed, 1013 insertions(+), 16 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/hi6220-clock.txt create mode 100644 arch/arm64/boot/dts/hisilicon/Makefile create mode 100644 arch/arm64/boot/dts/hisilicon/hi6220-hikey.dts create mode 100644 arch/arm64/boot/dts/hisilicon/hi6220.dtsi create mode 100644 drivers/clk/hisilicon/Kconfig create mode 100644 drivers/clk/hisilicon/clk-hi6220.c create mode 100644 drivers/clk/hisilicon/clkdivider-hi6220.c create mode 100644 include/dt-bindings/clock/hi6220-clock.h -- 1.9.1 -- 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
