From db04d6284e2a626791e959dc71e922e8570440b6 Mon Sep 17 00:00:00 2001 From: Stuart Longland Date: Fri, 8 Aug 2014 14:20:20 -0700 Subject: drivers/rtc/rtc-isl12022.c: device tree support Add support for configuring the ISL12022 real-time clock via the Device tree framework. This is based on what I've seen in the related ISL12057 driver, it has been tested and works on a Technologic Systems TS-7670 device which uses a ISL12020 RTC device, my device tree looks like this: apbx@80040000 { i2c0: i2c@80058000 { pinctrl-names = "default"; pinctrl-0 = <&i2c0_pins_a>; clock-frequency = <400000>; status = "okay"; isl12022@0x6f { compatible = "isl,isl12022"; reg = <0x6f>; }; }; ... etc }; Signed-off-by: Stuart Longland Cc: Roman Fietze Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/rtc/rtc-isl12022.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'drivers/rtc') diff --git a/drivers/rtc/rtc-isl12022.c b/drivers/rtc/rtc-isl12022.c index 03b891129428..aa55f081c505 100644 --- a/drivers/rtc/rtc-isl12022.c +++ b/drivers/rtc/rtc-isl12022.c @@ -17,6 +17,8 @@ #include #include #include +#include +#include #define DRV_VERSION "0.1" @@ -271,6 +273,13 @@ static int isl12022_probe(struct i2c_client *client, return PTR_ERR_OR_ZERO(isl12022->rtc); } +#ifdef CONFIG_OF +static struct of_device_id isl12022_dt_match[] = { + { .compatible = "isl,isl12022" }, + { }, +}; +#endif + static const struct i2c_device_id isl12022_id[] = { { "isl12022", 0 }, { } @@ -280,6 +289,9 @@ MODULE_DEVICE_TABLE(i2c, isl12022_id); static struct i2c_driver isl12022_driver = { .driver = { .name = "rtc-isl12022", +#ifdef CONFIG_OF + .of_match_table = of_match_ptr(isl12022_dt_match), +#endif }, .probe = isl12022_probe, .id_table = isl12022_id, -- cgit v1.2.3
