[PATCH v2 1/4] pmbus: associate PMBUS_SKIP_STATUS_CHECK with driver_data

[PATCH v2 1/4] pmbus: associate PMBUS_SKIP_STATUS_CHECK with driver_data

[Xiaoting Liu]

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.

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.

Assuming this is the Delta Electronics DPS-650-AB power supply, I think

Again, assuming this is the Delta Electronics power supply, this should
probably be something like "delta,dps650ab".

Thanks,
Guenter
