intergrated charger -> integrated charger ^ Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>
2012-03-26lp8727_charger: Fix wrong code styleKim, Milo1-5/+5
Definition of STATUS2 : remove space before tabs. Return code of lp8727_is_dedicated_charger(), lp8727_is_usb_charger() : remove parentheses when return is not a function. MODULE_AUTHOR section : remove space at the start of a line. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>
2012-03-26lp8727_charger: Change i2c functionsKim, Milo1-28/+20
On writing single byte via i2c, use i2c_smbus_write_byte_data() rather than i2c_smbus_write_i2c_block_data(). Name changes : lp8727_i2c_read() -> lp8727_read_bytes() lp8727_i2c_write() -> removed lp8727_i2c_read_byte() -> lp8727_read_byte() lp8727_i2c_write_byte() -> lp8727_write_byte() Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>
2012-03-26lp8727_charger: Add error check routine on probe()Kim, Milo1-18/+39
Add error checking on initializing registers and interrupt handler. Initializing registers - lp8727_init_device() : check i2c error during probing the driver. Initializing interrupt handler - lp8727_intr_config() : check an error on creating the irq thread. If an error occurs on probing lp8727 driver, allocated lp8727 driver memory is freed.

2012-03-26lp8727_charger: Add company name and descriptionKim, Milo1-1/+2
Add 'Texas Instruments' because TI acquired National semiconductor at 2011. And the driver information is added in the header file. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>

1. Useless braces were omitted 2. Useless void casts were omitted 3. module exit name changed lp8727_chg_exit -> lp8727_exit 4. Pointer coding style changes no space between pointer('*') and pointer name ex) u8 * data -> u8 *data 5.

2012-01-04lp8727_charger: Add supported i2c functionality check routineKim, Milo1-0/+3
lp8727 i2c r/w functions are based on SMBUS I2C BLOCK. So the driver needs to check whether i2c bus supports this functionality or not. Signed-off-by: Woogyom Kim <milo.kim@ti.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
