Patches are generated using the "format-patch" command from the following location: *https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base *rev=0771849495b4128cac2faf7d49c85c729fc48b20 Patches numbered 76/77/102/103 have already been integrated in 3.14.12, so they're not in this list. All these patches are either integrated are pending integration into kernel.org, therefore these patches should go away once the kernel gets upgraded to 3.16. Support is currently limited to AP148 board but can be extended to other platforms in the future. These changes do not cover ethernet connectivity.

+QCOM BAM DMA controller
|
|
+
|
|
+Required properties:
|
|
+- compatible: must contain "qcom,bam-v1.4.0" for MSM8974
|
|
+- reg: Address range for DMA registers
|
|
+- interrupts: Should contain the one interrupt shared by all channels
|
|
+- #dma-cells: must be <1>, the cell in the dmas property of the client device
|
|
+ represents the channel number
|
|
+- clocks: required clock
|
|
+- clock-names: must contain "bam_clk" entry
|
|
+- qcom,ee : indicates the active Execution Environment identifier (0-7) used in
|
|
+ the secure world.
|
|
+
|
|
+Example:
|
|
+
|
|
+ uart-bam: dma@f9984000 = {
|
|
+ compatible = "qcom,bam-v1.4.0";
|
|
+ reg = <0xf9984000 0x15000>;
|
|
+ interrupts = <0 94 0>;
|
|
+ clocks = <&gcc GCC_BAM_DMA_AHB_CLK>;
|
|
+ clock-names = "bam_clk";
|
|
+ #dma-cells = <1>;
|
|
+ qcom,ee = <0>;
|
|
+ };
|
|
+
|
|
+DMA clients must use the format described in the dma.txt file, using a two cell
|
|
+specifier for each channel.
|
|
+
|
|
+Example:
|
|
+ serial@f991e000 {
|
|
+ compatible = "qcom,msm-uart";
|
|
+ reg = <0xf991e000 0x1000>
|
|
+ <0xf9944000 0x19000>;
|
|
+ interrupts = <0 108 0>;
|
|
+ clocks = <&gcc GCC_BLSP1_UART2_APPS_CLK>,
|
|
+ <&gcc GCC_BLSP1_AHB_CLK>;
|
|
+ clock-names = "core", "iface";
|
|
+
|
|
+ dmas = <&uart-bam 0>, <&uart-bam 1>;
|
|
+ dma-names = "rx", "tx";
|
|
+ };
