The syntax of compatible property in DT is to mention the Most specific match to most generic match. Since AM335x is the platform with latest IP revision, add it 1st in the device id table. This way, we can add new matching compatible as 1st and maintain old compatible string for backwards compatibility. ex: compatible = "ti,am3352-rtc", "ti,da830-rtc"; Also, update am335x .dtsi file (am33xx.dtsi) as above. Note: This is a part of previously submitted patch-set [1]. Out of 4 patches, 3 was accepted and 1 got an acceptable NAK. Hence resubmitting only the rejected + updated changes. Changes in V4: - Rebased on latest linux-next (as on 160813). - Correct a type AM335X --> AM3352 Changes in V3: - As per Mark Rutland's suggestion [2], maintain old compatible string and add the new matching string as the 1st compatible. Changes in V2: - Coding style corrections (remove extra space, use lower case for hex numbers - use prefix ARM: for commit subject keeping with arch/arm convention) - use "[AM/am]3352" instead of "[AM/am]335x" to keep the all usages in sync. - Use index defined for struct members so they remain in sync - Add new compatible to existing one so that when driver supports enhanced features of hardware, they are available to the user else the basic functionality still works [2] https://lkml.org/lkml/2013/7/3/74 [1] https://lkml.org/lkml/2013/8/1/442 Hebbar Gururaja (1): ARM: dts: AM33XX: update rtc node compatibility Hebbar, Gururaja (1): rtc: omap: update of_device_id to reflect latest ip revisions arch/arm/boot/dts/am33xx.dtsi | 2 +- drivers/rtc/rtc-omap.c | 6 +++--- 2 files changed, 4 insertions(+), 4 deletions(-) -- 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
