From mboxrd@z Thu Jan 1 00:00:00 1970 From: josh.cartwright@ni.com (Josh Cartwright) Date: Thu, 8 Nov 2012 12:49:40 -0600 Subject: [PATCH v2 0/5] zynq clk support Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This set is a v2 of my original patchset "zynq COMMON_CLK support" [1]. This patchset is on top of the arm-next in the Xilinx tree[2], and also dependent on my patch "serial: xilinx_uartps: kill CONFIG_OF conditional", which I've removed from this patchset at Michal Simek's request. For easy testing, I've made available a branch with my changes here[3]. Changes since v1: - Dropped the moving of the TTC driver. This will be done in a later patchset. - Fixed TTC periodic tick frequency calculation - Updated basic peripheral clk to support devices with less than two derivative clks. - Fixed dts issues in the uart and ttc (thanks to Lars-Peter Clausen and Michal Simek). - Split out the creation of the clk drivers and the enabling of the drivers for the platform into separate patches. - Updated clk initialization functions to 'bail out' when an error condition is hit. - Addressed stylistic feedback from Lars-Peter Clausen. --- Patch 1 performs a dts file split for zynq, creating a generic zynq-7000.dtsi snippet and a zynq-zc702.dts board specific description. Patch 2 introduces the zynq clock drivers and bindings. Patch 3 enables the zynq clock drivers when building for zynq, and adds updates the zynq device trees to use the bindings. Patch 4 updates the xilinx uartps driver to acquire rate information via the clk bindings. Patch 5 updates the xilinx ttc driver to acquire rate information via the clk bindings. --- [1]: http://lists.infradead.org/pipermail/linux-arm-kernel/2012-October/129295.html [2]: git://git.xilinx.com/linux-xlnx.git#arm-next [3]: git://gi.teric.us/linux-zynq.git#of_clk_v2 --- Josh Cartwright (5): ARM: zynq: dts: split up device tree clk: Add support for fundamental zynq clks ARM: zynq: use zynq clk bindings serial: xilinx_uartps: get clock rate info from dts ARM: zynq: add clk binding support to the ttc .../devicetree/bindings/clock/zynq-7000.txt | 55 +++ arch/arm/Kconfig | 1 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/zynq-7000.dtsi | 166 +++++++++ arch/arm/boot/dts/zynq-ep107.dts | 70 ---- arch/arm/boot/dts/zynq-zc702.dts | 44 +++ arch/arm/mach-zynq/common.c | 14 +- arch/arm/mach-zynq/timer.c | 287 ++++++++------- drivers/clk/Makefile | 1 + drivers/clk/clk-zynq.c | 383 +++++++++++++++++++++ drivers/tty/serial/xilinx_uartps.c | 30 +- include/linux/clk/zynq.h | 24 ++ 12 files changed, 870 insertions(+), 206 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/zynq-7000.txt create mode 100644 arch/arm/boot/dts/zynq-7000.dtsi delete mode 100644 arch/arm/boot/dts/zynq-ep107.dts create mode 100644 arch/arm/boot/dts/zynq-zc702.dts create mode 100644 drivers/clk/clk-zynq.c create mode 100644 include/linux/clk/zynq.h -- 1.8.0
