Current code compares device name with name in i2c_device_id to decide whether PMBUS_SKIP_STATUS_CHECK should be set in pmbus_platform_data, which makes adding new devices with PMBUS_SKIP_STATUS_CHECK should also modify code in pmbus_probe().
This patch adds pmbus_device_info to save pages and flags. Its pointer is put in driver_data of i2c_device_id, which makes adding new device more straightforward. Signed-off-by: Shunyong Yang <[email protected]> Signed-off-by: Xiaoting Liu <[email protected]> --- v3: Remove an empty line. --- v2: Move struct pmbus_device_info definition location from pmbus.h to pmbus.c. Change struct name from default_pmbus_info to pmbus_info_one. Change struct name from pmbus_info to pmbus_info_zero. Replace struct name dps460_pmbus_info and sgd009_pmbus_info with pmbus_info_one_skip. --- drivers/hwmon/pmbus/pmbus.c | 54 +++++++++++++++++++++++++++------------------ 1 file changed, 32 insertions(+), 22 deletions(-) diff --git a/drivers/hwmon/pmbus/pmbus.c b/drivers/hwmon/pmbus/pmbus.c index 7688dab32f6e..ef845a1310fa 100644 --- a/drivers/hwmon/pmbus/pmbus.c +++ b/drivers/hwmon/pmbus/pmbus.c @@ -28,6 +28,11 @@ #include <linux/pmbus.h> #include "pmbus.h" +struct pmbus_device_info { + int pages; + u32 flags; +}; + /* * Find sensor groups and status registers on each page. */ @@ -172,13 +177,14 @@ static int pmbus_probe(struct i2c_client *client, struct pmbus_driver_info *info; struct pmbus_platform_data *pdata = NULL; struct device *dev = &client->dev; + struct pmbus_device_info *device_info; info = devm_kzalloc(dev, sizeof(struct pmbus_driver_info), GFP_KERNEL); if (!info) return -ENOMEM; - if (!strcmp(id->name, "dps460") || !strcmp(id->name, "dps800") || - !strcmp(id->name, "sgd009")) { + device_info = (struct pmbus_device_info *)id->driver_data; + if (device_info->flags & PMBUS_SKIP_STATUS_CHECK) { pdata = devm_kzalloc(dev, sizeof(struct pmbus_platform_data), GFP_KERNEL); if (!pdata) @@ -187,36 +193,40 @@ static int pmbus_probe(struct i2c_client *client, pdata->flags = PMBUS_SKIP_STATUS_CHECK; } - info->pages = id->driver_data; + info->pages = device_info->pages; info->identify = pmbus_identify; dev->platform_data = pdata; return pmbus_do_probe(client, id, info); } +static const struct pmbus_device_info pmbus_info_one = {1, 0}; +static const struct pmbus_device_info pmbus_info_zero = {0, 0}; +static const struct pmbus_device_info pmbus_info_one_skip = { + 1, PMBUS_SKIP_STATUS_CHECK}; /* * Use driver_data to set the number of pages supported by the chip. */ static const struct i2c_device_id pmbus_id[] = { - {"adp4000", 1}, - {"bmr453", 1}, - {"bmr454", 1}, - {"dps460", 1}, - {"dps800", 1}, - {"mdt040", 1}, - {"ncp4200", 1}, - {"ncp4208", 1}, - {"pdt003", 1}, - {"pdt006", 1}, - {"pdt012", 1}, - {"pmbus", 0}, - {"sgd009", 1}, - {"tps40400", 1}, - {"tps544b20", 1}, - {"tps544b25", 1}, - {"tps544c20", 1}, - {"tps544c25", 1}, - {"udt020", 1}, + {"adp4000", (kernel_ulong_t)&pmbus_info_one}, + {"bmr453", (kernel_ulong_t)&pmbus_info_one}, + {"bmr454", (kernel_ulong_t)&pmbus_info_one}, + {"dps460", (kernel_ulong_t)&pmbus_info_one_skip}, + {"dps800", (kernel_ulong_t)&pmbus_info_one_skip}, + {"mdt040", (kernel_ulong_t)&pmbus_info_one}, + {"ncp4200", (kernel_ulong_t)&pmbus_info_one}, + {"ncp4208", (kernel_ulong_t)&pmbus_info_one}, + {"pdt003", (kernel_ulong_t)&pmbus_info_one}, + {"pdt006", (kernel_ulong_t)&pmbus_info_one}, + {"pdt012", (kernel_ulong_t)&pmbus_info_one}, + {"pmbus", (kernel_ulong_t)&pmbus_info_zero}, + {"sgd009", (kernel_ulong_t)&pmbus_info_one_skip}, + {"tps40400", (kernel_ulong_t)&pmbus_info_one}, + {"tps544b20", (kernel_ulong_t)&pmbus_info_one}, + {"tps544b25", (kernel_ulong_t)&pmbus_info_one}, + {"tps544c20", (kernel_ulong_t)&pmbus_info_one}, + {"tps544c25", (kernel_ulong_t)&pmbus_info_one}, + {"udt020", (kernel_ulong_t)&pmbus_info_one}, {} }; -- 1.8.3.1
