Dear all,
I'd like to propose a new approach for PMIC generic driver.
In my opinion following issues needs discussion:
1. In proposed
int pmic_reg_read(struct pmic *p, u32 *val) the val is returned by pointer.
Now at fsl_pmic.c read value is returned by return clause.
I think, that passing pointer is a better approach,since errors from
i2c_read/spi_read can be
caught in upper layers.
2. Since I haven't got a chance to test SPI part of the fsl_pmic.c driver, I've
focused
mainly on I2C and place stubs for SPI.
3. Suggestions for struct pmic's additional fields for SPI are more than
welcome :-)
4. Now the pmic_core.c file consist of
#ifdef PMIC_I2C
{Code for handling I2C}
#else
{Code for handling SPI}
#endif
The same approach is used at fsl_pmic.c
I'm wondering if this approach shouldn't be replaced with on-time checking if
SPI or I2C interface is available.
This check can be performed by:
struct pmic *p;
if (p->interface == PMIC_I2C) {
} else {
}
It would allow to remove obscure #ifdefs, but on the other hand it will reduce
execution speed of the driver.
Thanks in advance,
Lukasz
