The exynos4 platform is only dt-based since 3.10, we should convert driver data and ids to dt-based parsing methods. The rotator driver has a limit table to get size limit of input picture. Each SoCs has slightly different limit value compared with any others. For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have 8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size for its X/Y axis. Thus, we should keep different tables for each of them. This patch also includes desciptions of each nodes for the rotator and specifies a example how to bind it.

|
|
|
Required properties:
|
|
- compatible : value should be one of the following:
|
|
(a) "samsung,exynos4210-rotator" for Rotator IP in Exynos4210
|
|
(b) "samsung,exynos4212-rotator" for Rotator IP in Exynos4212/4412
|
|
(c) "samsung,exynos5250-rotator" for Rotator IP in Exynos5250
|
|
|
|
- reg : Physical base address of the IP registers and length of memory
|
|
mapped region.
|
|
|
|
- interrupts : Interrupt specifier for rotator interrupt, according to format
|
|
specific to interrupt parent.
|
|
|
|
- clocks : Clock specifier for rotator clock, according to generic clock
|
|
bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)
|
|
|
|
- clock-names : Names of clocks. For exynos rotator, it should be "rotator".
|
|
|
|
Example:
|
|
rotator@12810000 {
|
|
compatible = "samsung,exynos4210-rotator";
|
|
reg = <0x12810000 0x1000>;
|
|
interrupts = <0 83 0>;
|
|
clocks = <&clock 278>;
|
|
clock-names = "rotator";
|
|
};
